ASTRO: M12

My last two attempts to get the Running Man out to my server and others
seems to have failed. It was finally picked up by
http://www.usenet-replayer.com/webrings/astro.html The first post that
is. Second seems to have vanished totally.

I don't know why I'm trying again but here is a very old M12. It was
made from 2 minute exposures and very few of those! Clouds must have
cut things short. In any case like M38 and NGC1977 it was found during
the latest drive cleaning. How I missed them in previous cleanings I
don't know. Anyway for what it is worth here's a very under exposed
M12, 10 minutes luminosity 6 minutes each color. I should have combined
all 11 images for a pseudo lum but just now thought of it. Oh well.
There are a pair of galaxies at the lower right (southwest) edge of the
cluster. The brighter one is PGC 1103219 (2MASX J16470200-0202314 ID).
The dimmer is anonymous as far as I can tell. A lot more exposure
time would have picked them up a lot better.

Nice picture Rick. I think I only imaged M12 once and wasn't very satisfied
with the result as it is quite low, where seeing is usually bad.

All your recent posts made it on my newsserver btw, but I have been away for
some days for some irish setdancing and did not have internet access there.

Yes, it seems to get to Europe fine but not my side of the ocean. Three
tries on Running Man and Space Banter is yet to pick it up!

Actually I took about 60 two minute shots of M12 but most were so fuzzy
they were unusable. I picked the three best for each color, none were
really sharp, and the 5 luminosity shots that were much clearer than the
others. Adding any more just made things worse. I didn't try using all
11 for a pseudo luminosity image. Might have helped but might have hurt
as some of the blue frames were not very good. I'll have to try again
under better conditions later this year.
