(IAAC) Re: [Planetary_Nebulae] 2 B's and a K

[Lewis J. Gramer]

Thanks for posting the URLs of those very fine images,
Carl! BTW, I was curious what the exposure times were
for the “B-V 5-2” image - you don’t mention on the site.

Now what are the chances that any of these “B-V” objects
have ever been observed visually?? Sounds like a “Deep
Sky Challenge” list for next year’s TSP... :)


As for K2-1, that one seems far more attainable for us
visual folks. I noticed Greg Crinklaw’s fine log of it
with a 16” scope on his SkyHound site, anyway:
 http://www.skyhound.com/sh/archive/dec/PK_173-05.1.html

And I also found a log from one of our fanatical Finnish
friends, Jere Kahanpää, for this obscure little object:
 http://www.funet.fi/pub/astro/dbases/observations/deepsky/other_pl/k2-1.jk.txt

But I could not ferret out any other amateur references
to this little fuzzy - although it was mentioned (with
no observing note attached) in the SECGPN. (Carl, you’d
probably find the notes in that compilation helpful, to
avoid problems like the one you encountered with K2-1!)

Just on a lark, I did find a great log of another member
on that catalog - K2-2, from the inimitable Yann Pothier:

More visual observations of interesting P-Ks, Ks and these
fine, obscure “B-Vs” are always welcome at IAAC, of course!
