Under a beautifully clear sky, about ten HAA members played host to just as many cubs plus their leaders and parents. As the sun left a gorgeous pallet of russet shades on the western horizon, views of Jupiter with many belts and four moons started the show.
The cubs ran excitedly from scope to scope as the astronomers gave explanations of what they were looking at. Then, once it was dark enough, Glenn led a discussion of what could be seen in the night sky, and demonstrated how to find the North Star.
Since October 4th was also the 50th anniversary of the the start of the space age, he also spoke about rocket flight and satellites. To give the cubs some idea on the time span a few people admitted (with some difficulty) to being older than Sputnik.
As if to pay homage, right on cue, the ISS made a flyby to everyone’s delight. For the cubs, though, Ann and Alex Tekatch provided the highlight of the night when they gave everyone small light sticks. These actually proved very handy in keeping track of that very active cluster.
After a few more views of the Andromeda Galaxy and Albireo, the cubs gave the astronomers 3 cheers and departed.
The sky remained clear though moisture-laden. The remaining HAA members took in some more of the showpieces and experimented with different eyepiece combinations. Friday morning commitments meant an early Thursday night for most, but overall it was another great outing.
Thanks to all who came out 🙂

Update By Kerry

I arrived a little later so by the time I got setup and aligned the cubs were ready to leave 🙁 They certainly were a very happy and excited group. Hopefully we can do this again… it’s always fun showing kids the night sky. Anyway, as it started to get darker we were noticing how incredible the Milky Way looked. It was probably the darkest that I have ever seen it at Binbrook, and then it dawned on Tim H that the fog overlying the surrounding area and cities was cutting out a good amount of the light pollution 🙂 I measured an SQM of about 20.47. Better than the average 20.1-20.2. We all tried to soak up as many DSOs so that we could take advantage of the conditions. A group of us stayed out observing till past midnight.. and still no fog. Binbrook was like a little clear sky oasis. As soon as I packed up and headed out onto the road I hit the wall of fog, and it never let up during my entire drive home. After I got home Bill (my hubby) reported some cool sights with the fog overlying the town of Grimsby below and moments of wonderful dark clear skies at our home a top the escarpment.

While observing in Binbrook, I concentrated mainly on the southern objects since I can’t see them from home:
Helix nebula- really large and diffuse,
Sculptor Galaxy- a tilted spiral that looked fairly large, diffuse and elongated in the 6in. This would probably look a little better if I waited till it rose a bit higher.
Both those targets will have to be on my AP list for next time I go to Binbrook.
We also viewed the Saturn Nebula… and I am proud to report that it does look a little bit more than just an out of focus blue fuzz and this is only in my 6in. With averted vision you can sort of make out a bit of the Saturn shape. I am sure Steve’s 16in would show much more.

Today, 4 October 2007, marks the 50th anniversary of the beginning of the Space Age with the launch of the first artificial satellite Sputnik 1 by the Soviet Union. From the Soviet test facility in the Kazahk Republic, the Russians sent aloft on their R7 booster (bigger then anything the Americans had at the time) a 180 pound (80kg) satellite which shocked the world with its little beep-beep-beep signal.

In addition to the initial fears of nuclear strike capability by the Soviets, it also began an age of unprecedented space exploration. This rocket, along with Sputnik 2 (Laika the dog) a month later and subsequent responses by the Americans in 1958 were all part of a international joint plan started in 1955 to mark the International Geophysical Year (Jul57-Dec58) to send satellites into orbit and explore earth and its environment.

As astronomers, this event ultimately had a huge impact on our activities, since it eventually spawned explorers such as Hubble, COBE, SOHO, Chandra, Galileo, Voyagers, Cassini and many others which has resulted in seeing space in ways we never imagined 50 years ago. And it generated new technologies which we take for granted today such as GPS, Goto mounts, CCD imagers, etc.

To mark this occasion, I wandered outside last night at around 1:30am to just look up and reflect on the wonder of our favourite pastime, the changes we’ve seen in our lifetimes, and gaze into the infinity of our universe. Without any optical assistance, I gazed upon many constellations like Perseus, Cepheus, Pegasus, Cygnus, and others. I saw Mars shining brightly, rising slowly over the roofline of the house. I was able to enjoy a bright green meteor that lingered for several seconds after its passing. And the primary goal I was seeking – 2 satellites passing overhead.

It’s fitting that tonight, we’ll be meeting up with a Cub pack at Binbrook to introduce them to the excitement of exploring space. Maybe we will be planting the seeds for a new generation of space explorers.

Happy 50th Anniversary! I can hardly wait to see what the next 50 years will bring.

Finding yourself awakened in the middle of the night is often a stressfull event for people, with worries of how to fall back to sleep, how tired they will be the next day, and the stillness of the night giving room for all their anxieties to run rampant. Then there are we lucky few that call ourselves amateur astronomers, and see such opportunities to get outside and catch a glimpse of the night sky that seasons to come will bring.
This is how I found myself at 4am outside with my pair of 15×70 Oberwerk binoculars in hand. Thew was a low (and I mean very low) cloud wafting past and obscuring the escarpment, and although it didn’t reach the ground, it was obviously no more than a couple of hundred feet high. Then a sudden break revealed that there was nothing above this low cloud, and a crystal clear sky showed through with a brilliant number of stars against a dark background. The entire Little Dipper stood out easily, so that should tell you how good the sky was. My binoculars roamed around the sky as breaks in the cloud presented first one constellation and then another to me. There was no order or sense to my tour of the sky; I was guided by the holes in the clouds and found myself looking north to the Double Cluster in Perseus, but no, the Andromeda Galaxy was obscured. Now overhead to Taurus, and the Pleiades never look better than through a good pair of binoculars. Mars looks so bright and is so high in the sky. Through the binos it appears in the same field as M35, that wonderful open cluster at Gemini’s foot. There’s Orion cutting through the fog, and even partially obscured the nebula still shows. The winter constellations are showing off their wealth of bright stars and as the fog thins in the east the path I am following leads to an extra star that would be found among the spring constellations just rising. The fog is still filtering it, and at first I don’t recognize it as Venus, but as the east clears it shines forth brighter than 4th magnitude, and my binoculars show a small crescent. It shows a similar phase as the Moon, which is not far from the head of Gemini, and which is showing a rich landscape that, as good as the binos are, makes me wish I had brought my scope out. A good part of the sky is clear now, and I move to find a view of the south and Orion again. Yes, here is a chance to see him without the filter of the fog and again I lift my binos to the sword. Of course I’ve seen it through these binos before, but perhaps because I saw the thinned out version through the clouds earlier I was now amazed at the extent of the nebulousity! Sitting amidst the stars of Orion’s sword, it seemed so large, with the wings going off the sides of the nebula were so clear. It’s wonderful what a pair of binoculars will show. Of couse I have had views through large scopes that show intricate detail and colour, but this has to be one of my favourite views of M42. A parting glance at the now completely clear sky shows the winter Milky Way cutting through many of these constellations
That’s it. A half hour of my time and a little fog to dance around, and back in bed after a wonderful observing experience. Well worth being tired the next day. And if anyone asks why I am so tired, well I’ve got stories to tell.

After just over 3 years with my trusty Canon 300D DSLR Camera I decided to move onwards to the new Canon 40D. It was well worth the wait to make this huge upgrade!

Last Friday was my first clear night to test it out… and even with the moon high, and in Gibbous phase I was still able to get some decent captures. The Liveview focussing was one of the many reasons that I decided on this camera. It is very hard to focus through a dslr on stars through the viewfinder and now with Liveview the task was made much easier. I could zoom into stars down to magnitude 4.5 for fine tuning. With it’s high speed for transferring raw files I was able to check each frame that was captured and view/organize them indoors for processing. Since my laptop is part of my imaging train.. it was nice to be able to focus on the laptop screen with fast response time, set up a timer for scheduled shutter release, and transfer each image… all with one USB cable.

Only negative… I now need more RAM. Processing went soooo sloowly.

Of course I wouldn’t just buy this camera for only AP. I also do a lot of daytime photography and after shooting with it for a few days I have noticed nice improvement in detail and colour saturation (especially in skin tones), and more reduced noise at high ISOs. I’m sad to have to give up the 300D but happy to have moved on. I’ll be looking into selling the 300D body with all original manuals, software, battery charger and Hap Griffin Astro Cable.

I got a call earlier today from Jim W. and was easily persuaded to head out to Binbrook, despite a nearly full moon. We had the place to ourselves, aside from some noisy raccoons and a few coyotes , and the moonlight gave a spectacular lustre to the lake and surrounding countryside. Jim mentioned that the CSC was forecasting a particularly steady night, and he was right. Comfortable temperatures, very little dew and deadly calm air promised a wonderful night of observing. So naturally I forgot my tube rings at home and couldn’t set up my scope. Alas! Jim, ever the gentleman, not only gave me a lift up to Binbrook, but now also offered to share his scope. We took in several nebulae (aided by a narrowband filter) a few good globulars (M15, M13 and M22) and several lovely open clusters, which did a good job of cutting through the moonlight. M11 proves to be outstanding under any observing conditions. I’m going to try observing it on the next cloudy night. Alas (again) even Jim’s 8″ couldn’t spot the Saturn Nebula. I guess you really do need a 74″ scope.

An early view of Jupiter showed an abundance of detail even though it was nearly on the horizon, and that was our first clue to just how good the seeing was. When we finally yielded our attention to the overwhelming brightness of the moon we were astounded by the amount of detail visible. The finest part of the evening was spent going over every bit of the lunar surface at high power. Jim set a new personal high by taking his scope up to 400x with the help of my 5mm Pentax eyepiece. This wonderful combination of objective and ocular elicited many oohs and ahhs (and a few other comments not suitable for a family website)as the moon showed nothing but a rock steady view and a landscape rich with detail. Terraced crater walls, rilles and ripples, and suspended crater rims hanging is the blackness of space over the terminator reminded us that our nearest neighbour is a much overlooked object. Even this most light polluted of nights gave us a wonderful observing experience just because that big, bright old moon was out there.

A little side bar on the DDO trip. Mike S. decribed the trip well and posted some wonderful pictures. He also offered Jackie much deserved thanks. I have to say that I had a wonderful time. The presentation was excellent, we had a chance to see a truly amazing instrument, and each of us undoubtedly came away with wonderful stories. I got Ian Shelton to recount to Mike J. and myself a firsthand account of the discovery of SN1987A, and Doug B. got the staff to let the two of us in to the library where we were able to peruse the books of Chant and others. And the view through the telescope was startlingly bright and richly colourful; both reminders of just how big a scope we were lucky enough to be looking through. Most of all though, there was lots of laughing and talking and enjoying the company of others, because as Michael S. so often reminds us, this really is a great astronomy club!

I arrived at Binbrook at 8:30 and joined some other intrepid observers and the keyholder.

The moon was high in the sky and quite bright… you could read by it, (unfortunately).

I set up the (Great White Scope) GWS and its trimmings, intent on performing the key experiment to determine what needs to be done with my XTi to get it imaging on the GWS… and with a sheet of paper i projected the moon into space in front of the open eyepiece portal.

It comes to a focus about 1.5 inches away from the edge of the scope, which is just a shade too short
to bring it to a focus within my Xti, so i guess i need to get fancy with the Crayford Focuser.
Jackie was amazed i could bring the moon to a focus on paper beside the scope.
Even more amazed when a large version of the moon appeared on paper when the eyepiece was returned.

I tested out my newly constructed switch for holding the ‘bulb’ mode of the camera, and made some time exposures of Andromeda, while Ann did the same. I noticed a difference in the amount of background glow and noise in ISO 1600 vs ISO 100 mode. Using the GWS as a mobile tracking camera mount was not my style, and i was finished after 3 exposures. The focus was good though. ISO 1600 really brightens up the photos.

We set the camera up to lock the mirror with a separate operation, to eliminate vibration when the exposure starts. I guess it’s overkill for the kinds of photos i was taking, but i am still keen to stretch Andromeda out of the noise.

Despite the sacrilege of using the GWS for astro-photos, i still want to see if it’s possible.
My next project will be to shorten the focuser and get a low profile t-ring so that the camera can snuggle close enough to the scope to get a focus. I guess i have not completely exhausted the chance to adjust the location of the primary mirror, which might propel the focal plane a bit further out of the focuser.

In one of my longer time exposures, i got some star smearing, indicating as misalignment of the EQ platform, (which i had set up by eying Polaris at the start of the evening).
I guess this is a case for using the DSI Pro as a tracking aid, along with a laptop and the tracking port on the EQ platform.

I did not have the luxury of waiting for the moon to set, even though i wanted to seek
M46 and M47 (as part of the Sequential Messier Marathon), which should be rising in the early morning. It turns out M49 is very near the sun right now, so that it will likely be mid October before that hurdle is cleared. By then it will be easy to get from M46 to M53, but M54 is in Saggitarius and will be setting too early. (I think i might be planning too far ahead here).

It’s going to be at least mid December before i get to M68, i reckon, so this is not going to be a quick romp. Some of those galaxies will be pretty low on the horizon, further complicating things.
So, with the SMM on hold…

I found a pumpkin orange star in Perseus, and noted it in my star charts. It does not have a name, and it’s probably 7th magnitude, but it sure is a nice colour. Definitely want to trot it out on visitors nights.
I was able to find for the first time Rho Cassiopia, and see it as a normal looking, if bright star.
There’s an open cluster not far from it, which i was also able to find.

I looked up M15, not far from the moon. The zoom eyepiece eventually served up a smatteing of individual stars, but the moon was definitely working against the deep sky objects.
The moon shining into the GWS caused all kinds of distraction in the eyepiece, as i could see the interior of the scope as i approached for a view.
Things were dewing up but my dew busters and primary fan kept everything nice and dry.

Time to make lemonade, and observe the moon, i guess.

I put a heater on my eyepiece, to keep it dry. It worked fine that way.

I finished the evening with a hunt for M74, brushing up on when i will need it first thing for the (non-sequential) messier marathon in march. I had the stars all aligned, and centered it nicely in the finder and the GWS, but i could not see it with the moon high in the sky.
That’s a clue to how hard it’s going to be.

It took 23 minutes to pack everything back into the car and i was out the gate before 12:15 am.

There’s plenty to see through the GWS whenever the SMM is not on, and the dew busters are working just fine. I now hear about frost, a whole new dimension of telescopic entertainment.

Got to Binbrook for a 3:00am gate opening – Jackie was soon to follow. The sky was crystal and calm as predicted (the CSC is going to get it right once in a while – it’s just a matter of odds). The moon had just set – the Pleaides were high in the sky and Orion was just clearing the trees.

After setting up and polar aligning I started testing my new IDAS LPR filter – first with the Pleaides – then with Orion’s belt and dagger.

It was the first time I saw Venus since it crossed over to the morning – it sure is high and bright.

Watched the Timothy Ferris TV special “Seeing In The Dark”, last night. Overall, I enjoyed it; it was well produced and had a nice feel to it, and it was nice to see a program that was centered around “our” aspect of astronomy.
However, I did feel it didn’t quite reach its full potential in a few places:

1) More time might have been spent interviewing passers-by at the sidewalk astronomy event to illustrate the interest of, and the impact on, the general public when amateurs put on these events.

2) More time might have been spent on star parties and the participants, particularly throughout a night of observing and imaging.

3) Although, he was trying to dramatize his own youthful experiences stargazing, by going back to the fifties (a la Beach Blanket Bingo), I think he missed a golden opportunity to grab today’s youth with footage of high school observing groups – or young astronomy award winners.

4) After professing the wonders of viewing the night sky, the end of the film shows him and his son inside playing guitars, while a computerized astrophotography set-up does all the astronomy. After the time he’d spent infecting the viewer with the lore of astronomy, that just seemed to be an odd way to end it.

But, for all that, the photography and graphics were really well done, and I’d watch it again. 8/10

Set up last night on the driveway to start imaging and wouldn’t you know, the minute I started, I noticed a smokey smell in the air. I looked up and I could barely make out the milky way. I measured an SQM of 19.47. Surprisingly the NA Nebula managed to show up in the frames. This was first time trying out my Celestron LPR filter. I really got lucky with the framing of this object, since it is so large that it took up the entire frame and I could barely even see it on the camera display.

Later in the night the SQM got up to 20.17 and I thought it would be nice to try M33.

By Kerry LH

I arrived at Lynden at about 10:30 pm and it was already starting to get foggy.
I set up the Great White Scope (GWS) out in a field where long views to the east and south would be available, and was appalled by the fog. There was so much fog i could play my laser through it and cut it in cross section. It was intriguing to see there were areas of no-fog embedded in the fog, and that it extended between 10 and 50 feet above me. At times there were layers of fog with fresh air between them.

Should i have known from the weather reports? They called for clear skies. I see the CSC still reports good transparency for Wednesday morning. They have not swept it under the rug yet. I do see a bright red patch on the Humidity line though. That will be a clue for next time.

Rather than take down the scope and try again tomorrow, i decided to wait out the fog, if that’s possible. The key curiosity was whether waiting out the fog is ever rewarded. I planned to use this evening as a standard to decide when to pack up in the future, if fog was coming in. I wanted to know if the skies could be redeemed. So i waited.

The Kendrick dew guard (DG-3) powered by a tiny 9v battery, on my secondary kept it fine all night, and although the scope was dripping wet by morning, the mirrors persisted just fine.

I also had a dew heater resistor-strip made by Tim on my findersope, and it was keeping it dry to the touch on the outside and just fine on the inside.
I lacked a dew heater on the eyepiece of my finderscope, which eventually needed some sympathy. I took the red dot finder off for a while and kept it in my pocket, in anticipation of clearer skies.

I perched my XTi on the GWS and took some constellation photos of Orion, and worked on getting the focus just right. I used my F1.8 50 mm lens. It fits the entire constellation of Orion into one shot.

I really need a gadget to support time exposures now. 30 seconds at a time does not yield much detail in each frame.

I had some fun with my laser watching tiny fog particles blowing through the beam,
and thought about what gets rid of fog… wind. But there was really only the gentlest of a breeze, and it was not blowing anything away. I wondered if starting the car could create some kind of fog-busting updraft, but i could not drive around in circles because that would kick up a lot of dust on the field. It was interesting to note that in some directions the laser seems to expire in the fog, and in others, it breaks through and the beam can be seen dimly extending further into the sky.

A big enough scope can see through fog – not.

But higher up the sky looked fine. The pleiades were shining out at me, so i trained the scope on them for a while. I would get them again much later after my Sequential Messier Marathon (SMM) made some progress.

Mars was bulging and contracting, occasionally looking round for a second or 2.

I decided to make sure the fog was not going to block all progress by looking for and finding M1. It was easy to see once i had the right spot in the sky. Thus encouraged, i went for a stroll, after putting the cover on my GWS and leaving the dew busters running.
I returned to the scene at about 2:30 am.

As the 3:45 am rise time of M41 approached, i started picking out stars near Canis Major. It turned out the sky was adequate above the horizon, but the horizon was completely fogged in.

I found the open cluster M41 at about 4:34 am, and made a sketch of it. It looked fine in the GWS, at 73x magnification. M42 and M43 were easy to find and see in the night sky, by then Orion was quite high up. M42, and M43 yielded some details and nebulosity which i also tried to sketch. The trapezium was easily split by the GWS.

M44 was a real devil to find in the fog. I could only see Castor and Pollux in Gemini, and there’s a page break in my sky atlas between there and M44, so judging distances and angles was really hard. The fog made star hopping almost impossible, and too difficult for me either way.

Venus was a nice sharp crescent moon shape. It is indeed very very bright. When it first showed up it was high enough that i did not see it rise, and i thought it must be an approaching plane. About 10 minutes later when it had not moved i realized my mistake.

Noting that both Venus and M44 were on the ecliptic helped to find M44, and eventually i could spot it in the fog, in the finderscope, and bring it in with the GWS.

M46 near Canis Major was to prove too difficult to find. Then the fog came in so thick i could hardly see the buildings, and the laser showed it to be a solid layer more than 50 feet thick. It was time to stop. The sun was going to rise in an hour and there’s no way i could see DSO’s against this background. I started the car and put the heater on, making a bit of a drying kiln, to put pieces of the scope in, after toweling them off. It took a while but my buddy and i had a chat while i disassembled the GWS and put it safely back in the car.

It never occurred to me the CSC would report clear skies all night but i would be fogged in. Now i have a new appreciation of what can go wrong at a star party. I would say it was not the best of nights, but now i know that the dew busters i have can stand up to anything. I just need some eyepiece heaters now. I am looking forward to crisp winter nights with good seeing, where dew will not be able to send me home, no matter what.
