'Hercules' from Sierra Remote

[Martin Pugh]

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.

Also in the image at lower right is NGC 6207 - the owner of SN 2004A, but no longer visible in this image.

cheers

Is that a teensy planetary i spy to the left of the globular? Awesome!

Wow - another amazing image. Your remote observatory sounds intruiging... do you have a link to some details about it?

[Martin Pugh]

Thanks everyone.

Yes Dave, there is a link to Heaven's Mirror observatory here:

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

Cheers

Impressive image and set up Martin. With that seeing and your skills I am expecting a costant flow of stunning images now from the 17"

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

[Martin Pugh]

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
Martin

Congratulation Martin, another amazing result... and a dream setup/location. I'll wait for the next ones.

All the best,
Leo

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:

The section on M13 starts on p. 62. M13 star positions start on p. 67.

Thanks everyone. Yes, 2 APODs in one month. Pretty happy about that.

Randy - excellent detective work, and many thanks for that.
