NGC 281 The Pacman nebula

Post by John O'Mahony » Sat Oct 17, 2009 3:46 pm

After my second night attempting to image this I finally managed to get some type of picture before the mist rolled in again. Two hours setting up the mount, unknown tracking errors, a slipping tripod screw and finally the haze :x

I managed to get 60 minutes of exposure although I wanted about 2.5 hours through the Megrez 72 before the weather broke.

20 x 3 minute subs.Canon 450D (unmodded and a CLS filter)
I was also using the new Skywatcher field flattener. It looks like it did a pretty decent job with the Megrez 72 (ignore the tracking errors

A good image there John, the tracking doesnt seem so bad to me.
Like you say a longer exposure would be of benifit.

Carrying around my 20" obsession is going to kill me, but what a way to go. :)
