Do you have automation software to do this?

I have found that giving a really good cool down works well. I generally automate to refocus after each sub frame, but the long cool down is really necessary to manage the focus shift for the first two hours.

Beautiful image, Peter! Would love to see a comparison of this Ha data with the SII and OIII channels.

Hmm! Perhaps this is why the SBIG AO product pages only show images of single and/or binary stars, as opposed to an entire edge-to-edge field?

No... but I also have other reasons to check every 10 minutes....(this happens to me a lot)

I think I've addressed this earlier...suffice to say that's not the experience I've had...plus it would seem to be a helping factor in Martin Pugh's stunning images.

A very nice result, Peter! Hope you get enough good weather to complete a colour version.

Cheers,
Rick.

One of my preferred area of the sky, good one, can't wait to see with color added

Thanks guys. I've started collecting the SII data...6 hours and counting, but have to say, it sure is dim in the SII part of spectrum. Looks like it needs 4x that!
(had a quick look at the OIII...also seems equally dim...sigh..)

Can't wait to see what colour you add Peter! A beautiful field with nicely balanced processing.
