Image of M81 and M82 (above) captured by our member Graham Caller using a Canon Dslr.

Graham comments:

“Amazing what a bit of accurate polar alignment does for the shots. I’d been having trouble with star trails appearing after 60 sec exposures.
A bit of research later, lots of learning how to polar align accurately without plugging into a computer or mastering drift aligning and voila 150 secs exposures. (I should have pushed 180 but that’s another night)
It was cold and late when I finished but imagine what another hour of data could show. Good to see less noise with longer exposures. Attached also (below) is my first attempt on 2nd Feb.”
