Great image Bill, well done.
Nice touch with the star spikes.

Ah a favourite region that!

You are getting some nice results with that unmodified DSLR and SN Bill

Everyone on this group seems to be using DSLR's..? It appears that I am the only slave using a mono CCD and filterwheel?...sigh...I feel so alone

Ooops, ok it wasn't done with the SN but the 80ED

Did you use a focal reducer on the 80ED or was it taken at the native F7.5?

Did you crop the image at all?

How do you find MaxDSLR to work with?

Cheers

Mike

Native 7.5 on the 80ED.

The only cropping was to remove stacking shadows at the edge of the frame, so the field of view is about 1.75 degrees.

MaxDSLR is a good product for aligning and for doing log stretch, bias and (sometimes) flats, however for those special shots I prefer to use it do a manual alignment because sometimes it rejects quite a few of my good subs (for reasons unknown). By doing manual star alignment it also lets me have a close look at star/image quality and to reject images as need be. With MaxDSLR you can't do any image processing other than basic stretch and curves. There's no histogram for example.

Now that I've got a new laptop I intend trying MaxDSLR's autoguiding and image acquisition features. Hope they work.
