Bill - I managed to squeeze as much out of this as I could.
The images have three major issues:
1. Field rotation - though Registax can do a reasonable job of fixing this if you use the 'rotate' option when you stack
2. The 'flare' at the top of the images makes it difficult to process evenly
3. A gradient, top left to bottom right - fixed in Photoshop. Could be related to 2
Its not a pretty picture - but you're well on the way. I suspect that you many of your previos images would actually be similar to this one. The processing part of it is by far the trickiest but you CAN squeeze a lot of detail from an image that you can't see at first glance. Welcome to the world of astrophotography....
By the way, you may want to save the image and take a peek on your own screen. Uploaded files always seem a little darker to me in Explorer....
Cheers
Dave

Of course it's a pretty picture Dave, it's mine, also it's got more flair, sorry, flare than Kylie :lol: :lol:
Thanks Dave, Both of you Daves may well make me lazy here, I will take the images and send them to you both for processing, that's what I call Auto-processing :lol: :lol:
Cheers,
Bill.
