Title: M81/M82 Widefield...
Post by: RobertM on May 17, 2009, 21:37:05
This was taken from Kelling Heath.

10 x 300s exposures stacked in MaximDL with a bit of tweeking in PS

Taken with EOS450d + 200mm lens @ f/2.8 on an Astrotrac mount, no filters ISO 1600

Unfortunately a bit of drift as PA wasn't quite close enough but not too bad otherwise.

John,  I've had an Astrotrac for nearly a year but I need to use it more often.

I'm taking it to DSC so you can see it there if you're going.

No joy with the Webcam as yet, might have another go tonight but I suspect the CCD is a duffer.

Great image.

Bring the webcam to DSC, I am sure between us we can sort it out or write it off.

That's come out very well Robert.  It shows the how useful an Astrotrac is!
