All,
It has been a really cloudy Spring here in North Texas and the clouds
finally parted, mostly, last night so I grabbed the following image.
http://www.celestial-images.com/Images/M13-16x300s-L.html
253mm RCOS @f9 - 2300mm of focal length. STL11K, guided off axis with
STL Remote.
Only fair transparency so I will wait for the color data.
Regards
Bill

It seems pretty poor considering the instrumentation. It seems you
have a kind of ghosting somewhere along the optical train. Have flats
been taken and properly applied? Because it looks like you haven't and
you're not going to get anything close to decent without 'em.

Andrea,
Thanks for the comment.

I don't alter the star sizes or clone out reflections

Probably not because I did it <g >

It's been a cloudy Spring just about everywhere.
Really fine capture though - thanks for posting it.
