IHOP (8/19)

by Alvin Huey

When I arrived at 6:30PM, Shneor, Bill Vance, Sheldon Berkowitz and George Malyj were already there and setup.

Rob/Melissa and two others; grandpop (forgot name) and Tee, Darrell Lee, Matt Tarlach, Dan/Renee, Randy Muller and Dax Castro and his three boys showed up in that order.

Rob brought his new WO ZS110 triplet refractor on a Vixen GEM mount. Bill with a FS-128 on a Tak GEM mount, George with his home built 18" truss, and Sheldon with 8" Meade SCT. The usual suspects brought their usual gear.

A couple people got a chance to try out the TMB Supermonocentrics and Tak LE's and they apparently liked it. The problem is that you can't get them anymore as it is not being made...but perusing AMart may turn one up once in a while.probably long while and expect to pay some serious bucks for one or two or more.

I've observed some Arp galaxies, a couple Palomars globular clusters while waiting for Andromeda to rise a little higher.

Anyways, here is my OR of some Arps from Saturday night. Looking forward to this Friday night at IHOP (8/25).

Arp 45 - UGC 9178 (Bootes)
22" f/4.1 reflector @ 327 and 458x
UGC 9178 - Faint and elongated (2:1) PA=45, even surface brightness. Size is about 45" by 15". The companion on the west end is not detected. Also noticed a small faint round smudge about 1.3' SE of UGC 9178. Even surface brightness and about 15" across. Researched and found it is a 16.1 magnitude elliptical.
A 10.4 magnitude star lies 1.1' south.

Arp 145 - UGC 1840/Anon 0220+41A (Andromeda)
22" f/4.1 reflector @ 327x
This is a pretty interesting pair. At first look, only Anon 0220+41A was visible. Upon further scrutiny, a hazy smudge just to the north of a pair of 13th magnitude stars popped into view
Anon 0220+41A - Considerably bright, round, even surface brightness. 30" across
UGC 1840 - Extremely faint fuzzy round spot merged with two stars to the south. Faint extensions to the north. Size is about 45" across. Anon 0220+41A lies about 30" due east.
