Getting better with non-guided shots, this one is 30 by 1 minute. The scope is a very,very widefield one,as you can see. Sheesh, it's only 430mm F/L. I really like how it puts each object into context.
Left the satellite trail in, thought it adds something. Then again, couldn't be bothered re-stacking. Yet another check to perform before working on an image..
It's a little emission neb I think, which you have picked up really nicely. It often shows up in wider field images as a few pixels of red in the Coal Sack. Being round it kinda looking like a planetary neb but pretty sure from memory that it's not. It has a horribly long designation. If no one else posts I'll try tracking it down for you later.

Thanks Cam. Do you or anyone else know of a decent plate solver (not too expensive) that I could try? Astrometry is proving to be insufficient for all the nice objects I'm seeing in these images.
I have pixinsight, I'll need to look up how to use its similar tools.

The nebula you are probably talking about is RCW71 aka Gum46.
astrometry.net will create a FITS version of the image with the coordinate WCS information embedded.
Very nice Simon. One look says Takahashi. Very satisfying to achieve a nice result unguided, and at 430mmFL. Terrific.
Now that's a lovely sentiment, thanks. It's taken me awhile to try and do the scope justice, a pleasing learning curve. Yes, it's so good to get reasonable subs unguided. Waiting for a guider to come soon, it'll be even sharper in the near future.
