Two shots of M101, my first attempt at this dim face-on spiral galaxy. 19 three-minute subframes here. 9 5-minute subframes on this one.

M51, The Whirlpool Galaxy in Ursa Major
This is my first halfway decent shot of M51. It’s a *lot* smaller than most of my targets. This is a stack of 10 five minute images, and it looks like I […]

M106, Spiral Galaxy in Ursa Major
My first attempt at M106 came out not-too-bad. Could use better focus. And more exposure time. And finer image scale. …but not bad. I’d like to take this opportunity to thank the […]
Re: CR-1 shims
Hi Jimbo, Sounds like you need to increase the load capacity of the focuser. Turn the 2 set screws located under the MoonLite logo in a CW direction about 1/20th of a […]
