Re: (IAAC) Obj: HICKSON 40 ARP321 PGC27509 - Inst: 40Cm(16")Dob
A nice report. Thanks for sharing it. It was particularly interesting to
me since I am awaiting delivery of a 40cm dob *and* have some HCG's on my
target list. I'm using an 8" SCT (C8) now. The only HCG I've seen (or
tired for that matter) is HCG44 - NGC’s 3185, 3187, 3190, and 3193. I was
able to see three of them rather easily, but 3187 escaped detection. I'll
try to post an official log this weekend.

BY David Levy,titled Meet Larry,Moe,and Curly.I had in the last couple of
months aquired my 40cm telescope and this seemed an ideal target to try for
as it was close to my maridian at the time of reading the article(keeping in
mind we get Sky&Tel quite a bit later than our northern Hemisphere
