Hi Roger,

Having seen the single file you sent me, you have stars resolved right into the centre.  This stacked process is showing the centre over stretched and losing the stars in the middle.

See if you can refine your processing skills to improve that.

It was a very impressive single frame, so if they are all like that then might as well make the most of it.

Also there is something weird going on because M13 looks squashed as does the bright star on the right.

Revision is a lot better Roger.

Its odd though that your image looks squashed on OAS forum but if you click on it is looks normal in Astrobin.

I do it like that so that Doug can save it ok
What do you use when you post an Astrobin image on OAS
This is how i do it but if theres a better way then let me know.

I paste a URL from astrobin into the "image" icon, and doesn't come out distorted like yours.

That's the icon far left of bottom row.  Hover over it - it says "insert image".

I tried to do it with your image but it wouldn't let me, is it in your staging area?

Glad i found the easy way to do it..lol
Better now.

A good result.  The differences in star colour are beginning to appear and the core is not saturated.
