Hello everyone - next off the processing line is M13.
Got a bit to say about this, so bear with me.
When I drilled down to the core, this single green star stood out like a sore thumb. The colour data is properly calibrated, and this star is perfectly formed, but why it is green is beyond me (I dont think this is Barnard 29)
So:
Two versions of the image linked below:
The first is how I processed the image before I spotted this green alien.

Revealing this star in a fully stretched/processed image is very difficult, so I reprocessed the core and blended it into this second version.

To see the green star in all its glory, click here (http://www.martinpughastrophotography.id.a u/images/Heart-of-M13.jpg):
Also in the image at lower right is NGC 6207 - the owner of SN 2004A, but no longer visible in this image.
cheers

Incredible image Martin. I was going to post a M13 image myself but I don't think I'll bother now.

Another corker Martin. Beautiful sharp field. It's quite amazing to see so many background galaxies. It adds real depth to the whole vista. :thumbsup:

Thanks very much folks.
Marc, what you say is what I enjoyed most about this image - look closely, you can see background galaxies between the stars! Amazing!
thanks for looking

Thats amazing resolution, I had a look at my M13 when I was in the UK and there is a green star too in my image I never noticed and some cyan looking stars as well.

I decided to do some detective work and see if I couldn't figure out how to find Barnard 29 and the green star. The green star appears to be star 202 on Barnard's M13 list. It's variable. I wonder how many days it was between your first and last exposure? I downloaded the APOD hires BMP and looked at it in MS Paint. Star 29 (the blue one) is at x=1068, y=1117. You can see all of this for yourself by looking at Publications of the Yerkes Obs., Vol. 6. Look here:
http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?bibcode=1931PYerO... 6....1B&db_key=AST&page_ind=69&plate_select=NO&data_type=GIF&type=SCREEN_THMB&classic=YES
The section on M13 starts on p. 62. M13 star positions start on p. 67.
