M109 and M13 on May 7th

Sorry for the very late post…

The night of Sunday May 7th (at home) was very productive with the 6in SCT. I started out by doing a bit of galaxy hunting… I just can’t resist faint fuzzies. Anyway I spent a little while looking for m109. It was a bit difficult and I thought I was looking in the wrong spot till I hooked up the camera to image it and lo and behold it was there, and I was looking in the right spot after all. I guess the conditions have to be exceptional for this galaxy to show itself easily. I roamed around in Leo and Virgo a bit before aiming my scope at M13. I was determined to get a better image of it. The last one was only a 30 sec exposure and had pretty poor tracking. This time since getting a polar scope installed (thanks Tim) I had much better tracking. Also, I actually was able to achieve a pretty good focus with the aid of a bright star which was far from M13 and surprisingly the focus held together well when aiming back to the target.

Here are the specs:

Imaging Notes, 7 May

PERFECT WEATHER MONDAY 7TH MAY

Five days of clear skies! wow, and Monday night was excellent, too. I imaged from the pation in Hamilton. Although the air is polluted, it’s possible to capture galaxies from the patio! Here is an image of M51 taken this morning after removing the skyglow:

Bob C at Spectacle Lake Lodge

Greetings from Spectacle Lake Lodge, near Barry’s Bay. Here I am, up here on my semi-annual astrophotography trip to my favourite dark-sky spot, hauling my Canon Digital Rebel 300D, my Tamron 300mm f/2.8 telephoto lens, my Super-Polaris equatorial mount, and all the gizmos that go with them. I’ve been more known as a hanger-on of film sky-shooting, but this is my first DIGITAL trip.

Last night (May 6, 2007) was spectacular, and very dark, and I went shutterbug crazy, taking 30-sec, 1-minute and 2-minute unguided time exposures of a pile of deep sky objects, especially galaxies, including M101 in Ursa Major:

This is a very closly-zoomed-in excerpt of my image of M101 taken Sunday, May 6, 2007 from the lodge. It is only a two minute exposure, at f/2.8, at ISO 1600. I will be posting images from my trip on my web site and in my HAA Gallery soon.

Stay tuned.

Saturday Night’s Alright, but Breezy and Cool

Saturday proved to be a reasonably good night for viewing (relative to what we’ve had over the past many months).

Jim W, Kerry-Ann H, Tim H, Steve G, Glenn & Gail M and I set up for a mini star party to take advantage of the clear skies before the moon rose. Some of the group were real troupers. They had been down at the photography show in Toronto and a few even took a little detour to a local astro store. Others had been working or coming off nightshift, but still had the energy to come out for observing. Talk about devotion to a worthy cause!

After scoping out (pun intended) the scouts that were sharing the park this weekend, we set up over at the boat launch area to reduce the effect of their lights, and damaging the grass. When we arrived, a few stray cirrus clouds were just disappating leaving us with clear skies. The forecast had indicated winds to be up to 25kph, but they were light – initially. It looked like it was going to be a nice evening, but the seeing was likely to be unsettled.

I set up my goto controller and attempted star alignment for the first time. Once aligned, I found that the controller didn’t always get me very close to the intended object. Clearly I’ve got to do a better job of picking more appropriate alignment stars closer to the ecliptic instead of using some high at the zenith. But it got me in the area and it tracked quite well. It was fun punching in some objects and having the controller get quite close. I even attempted a few photos with my EZ mount and point&shoot camera. Exposures were all wrong, but for a change, there wasn’t any star trailing. It’s a start.

Tim and Kerry were working on a mix of some photography and visual observations. I think Jim even tried a few shots. But most of the the night was spent viewing a variety of objects and sharing views in each other scopes. As usual Glenn was challenging himself with some new targets for his log. The scouts even came down to look through some of the scopes and ask lots of questions. Must be working on their astronomy badge.

Unfortunately a strong breeze picked up during the evening and made the cool temps feel worse than they were. Gail was well prepared with her long-johns and multiple layers, but not everyone else was so well attired against the wind. I set up a small campstove to heat water for coffee and tea for those that wanted some warmth.

Early, we were looking at Venus, Saturn and a number of clusters. Later, we added some galaxies. Once Jupiter rose around 11pm some of us tried to look at it, but the haze near the horizon made details difficult. We could see 3 of the major moons, but we couldn’t tell if the 4th was behind or in transit. As Scorpius rose, we tried for some of the nebulas nearby, but the conditions were too bad.

Eventually the wind and the cold got the better of us and we finally packed up around midnight. Aside from the cold breeze coming off the reservoir, we really enjoyed ourselves and saw quite a bit considering the conditions.

A fun night with a great bunch of active club members.

THE RIGHT PLACE AT THE RIGHT TIME… by Glenn

Don’s choice of viewing location was perfect in that it afforded a good surface for setting up, and kept us away from the scout’s bright hurricane lamps which were still burning at midnight.

It was nice to observe with a group after so many months of waiting for the right combination of conditions, and while the seeing wasn’t the best, transparency was quite good. For me, however, the timing was perfect as I was finally able to bag spiral galaxy M83, in among the trees at 11:30pm, which leaves only M74 unresolved on my Messier list.

For the scout visit, there was an excellent assortment of equipment on hand to give the best views of planets galaxies, globs, and open clusters. Enthusiasm ran high among the visitors and guests, alike. So, just like Don said – Saturday Night was ALRIGHT!

Update by Tim Harpur:

Last night I tried doing some unguided imaging using my 400mm telephoto camera lens instead of my usual imaging through my scope – the following are some of the results.

Whirlpool Galaxy - M51
Sunset at Binbrook

Update By KerryLH :
It was a blast observing with everyone last night. The company of such enthusiastic people made the night so enjoyable. Are other astronomy clubs like this? Anyway I planned on doing some imaging but never got around to it. I was really enjoying comparing the views of many faint fuzzies in the different scopes. I saw M83 in Glenn and Gail’s scope but couldn’t find it in mine. My GOTO alignment was off for the low southern sky. I searched a little with the aid of my Rigel Quickfinder but was quickly drawn away to viewing another object. Later in the night we were viewing the Ring Nebula, Jupiter and other rising objects. I came to the conclusion that I LOVE binoviewers. The views through Don’s scope was so much more relaxing and easier on the eye. Not to mention it seemed like I could see more detail. This will be one item to add on the astro shopping list.

Nice widefield images, Tim! …and thanks for helping me with setting up my polar scope.

Don, thanks for the tea! It gave me enough of a jolt to make it through the rest of the night.

Steve’s Update:

It was a fine evening to be in Binbrook, except I forgot to dress for 10 degrees cooler than the thermometer. I did have a jacket though, and got by fine.

My experience with the Messier marathon allowed me to zoom in several
objects without much fumbling, which was proof to me that I had definitely come a long way from my first night out.

My binoculars proved valuable to the scouts and their leaders alike.
The parallelogram made it easy for different people to see the same object without a runaround or ladder. The Beehive Cluster definitely answered the question ‘Why do they call it the Beehive Cluster?’.

I heard about a ‘bino box’ and am keen to see one in action. For observing at the zenith, it’s almost impossible to do so comfortably with just a standard mount.

I could zoom in M13, Jupiter, Saturn (a yellowish dot, not round) and M81-82 and M65-66. The Pocket Sky Atlas helped confirm the view was right even if the objects were not obvious in the eyepiece.
Of course, the best part was checking out the views in all the other scopes, as items were found and advertized.

Also very interesting was watching the setup and takedown of the scopes, which will help me decide what kind to buy. In particular, the alignment process. The above remarks about alignment underline the need to give the scope every advantage in the process.

I definitely need a bit more than super binos because a lot of objects end up being pretty tiny at 15x magnification.
However, I will lose light if I don’t increase aperture… so I am wondering. I would also like to try some imaging now that i have seen what can be done and the fine results that are obtained.

I was definitely encouraged by the warm friendliness of all the members present and their breadth of knowledge on the equipment and techniques. ‘Worth the drive to Binbrook’ — or anywhere else. They also planted the idea of going to Starfest this year. I’ll be there if it’s anything like Saturday night. Thanks, HAA.

A GOES Flare

From Mike Jefferson:

Last night @ ~ 8:00 EDT(midnight UTC) GOES 11-12 reported a top-of-the-scale C-class (almost an M-class) flare! Most powerful one I’ve seen. Mike J.

PS. Aurorae?

Sun Flare

Mike Jefferson reports that the GOES Satellite System recorded a nice C-Class Solar Flare on April 24th – perhaps the Sun is waking up; if we don’t get an aurora, perhaps there’ll at least be a sunspot to look at.

Observing at Kerry’s

Had a great time observing with Kerry. Arrived about 8:30 and got setup and after some problems with alignment we got to some deep sky observing.looking at several galaxies, globular clusters, and double stars. I had a early morning Mon. so packed up about 11:00 or so

Kerry’s update: Although we were expecting more obervers we still had a great time. I also had a nice opportunity to compare views of many DSO’s between my 6in and Jim’s 8in SCT.

Near the end of the night I decided to try out some imaging with my new setup the 80mm and c6 mounted side by side. I imaged through the c6 and had the 9mm illuminated reticle on the 80mm. There I was manual guiding for the first time ever (Tim Harpur makes it look so easy) Anyway after Jim left I managed to get a hang of the guiding and only had enough energy to get a few shots of M51 ~4 minute exposure each… see the results below. A little noisey and could have benefited from more frames but it is a first and there is always room for improvement 🙂 Tips or suggestions are very welcome…

ASTRONOMY DAY, 21 April 2007

Night Photos (by Tim Harpur)

Lyrid meteor shower

The Lyrid meteor shower is due to reach its peak around 4:00am Sunday. The CSC is predicting very favourable viewing conditions.

Galaxy Trot

I didn’t have a lot of time to observe, last night, but the beautiful crescent Moon / Venus combination drew me under the clear skies above my backyard observatory.
The air was calm and the humidity about 55%, enough to soften the edges of Saturn and its rings, and give a bright beam to my laser pointer (my new test for transparency 😉
Still, Leo and Ursa Major were well-placed for a little galaxy hunting so I got busy and managed to bag the following 10:
M65, M66 (couldn’t pull in the NGC companion), M105, NGC 2903, M81, M82, M101 (you really have to know what you’re looking for to get that one), NGC 5194 & NGC 5195 (M51), and M94 which has a surprisingly bright core – almost looks like a tiny globular.
Overall, not bad for an hour’s observing 🙂
