Title: First in a while...
Post by: JohnP on Jun 01, 2009, 14:27:14
Took this last night using ED80 & Atik 16ic. Image is 13 X 10mins through 13nm Ha filter (still not happy with guiding). This is a close up of the neck region - known as ic5067..

Cheers, John

That's very nice John.  I love doing these active regions of nebulosity, there's so much contrast and it really comes to life when you go deep like this.  Regarding the guiding, there seems like a little elongation but it's pretty good. Check what direction the elongation is (NS or EW) and that will indicate which axis is the problem.  Also whether it's drift if the image moves over the course of the session.

Hope that helps
Robert

looks like it is EW - I guess my polar alignment may have been off a tad...
