Taking Tim Harpur’s advice on focussing resulted in the best digital photos I’ve taken yet! It took some practice, but I managed to get decent images of the moon and Comet 73P last night from our backyard. I used my Canon G3 camera (an oldie but a goodie!) attached to a Scopetronix maxview adapter/eyepiece. For the comet, I used the camera’s longest shutter speed: 15 secs at f/2.0 and an ISO rating of 100 (my 400 rating causes too much noise in the images). Although the image is tiny, it isn’t bad for a first effort. (At least, that’s what I keep telling myself!) Because I took the image through the telescope’s star diagonal, the image is mirror-reversed.
I also took an image of the gibbous moon. I used the photo editing software to un-mirror-reverse the image and crop it, but that’s the only processing I’ve done.
These are not nearly as good as the images Tim Harpur has been taking with his Digital Rebel XT, but, hey, I gotta start somewhere!
