I'm just curious, what's the smallest aperture anyone has seen the very faint globular cluster NGC 7492 in Aquarius? I haven't seen it since August 2003, and...
Hi Kent, ... I've seen it with my 6" newt at 51x. I recorded it as a faint fuzz with a star at the east edge. Clear skies, Wouter -- People: "If she weighs the...
I'm sure this isn't the smallest aperture that will respond but here's an old observation I made with a C-8. I'm guessing a 4"-6" would do the trick? 8"...
I picked it up in 1990 from Anderson Mesa with my 15cm refractor at 50x. The low surface brightness will be the problem for most folks. \Brian...

I know of a non observation of that guy in a 25 incher from Columbus, Texas east of Houston on a wet night two weeks ago while it was still somewhat low. ...
Hi Kent & All, The smallest aperture I've seen it in was 25cm and it was not an easy object at x138 or x176 under an excellent rural, but not pristine sky....
Evidently my earlier post did not come through. I viewed it in 1990 from Anderson Mesa with my 15cm refractor. I found it easy to spot at only 50x, though...

Seeing Brian's note about viewing NGC 7492 in 1990 made me research my own notes. Oddly, the first time I at least LOGGED this object was also in 1990, on...
... It may be slightly brighter at the Mesa now than in 1990, but I simply haven't looked for it since then. If I get a chance, I'll try it with the Pronto...

Last sunday evening, Dana Patchick found a nice planetary nebula candidate while examining on-line POSS plates. It is at (2000) 17 09 38.6 -09 00 41, and has...

Howdy all; If you are ready to take an observing break, this is an easy object to locate. Put Delta AQR in the field of a low power eyepiece, turn off the ...
I agree this is the visible counterpart to IRAS 17069-0857, but it is listed as a galaxy in various places. From the data available through VizieR, I'd say...

I always find it interesting to compare the brightness of such suspects on the different plates that are provided at the DSS Plate Finder of the STSCI ( the...
Hi Brian, I checked NED and they just had the IRAS object without any classification other than being an infrared source. SIMBAD also had the IRAS object...

The area around NGC 7331 is close to my heart, too. I saw those "fuzzies" around NGC 7331 long ago; before any atlases available to me showed them. I was...
The comet was easily spotted this morning, and I estimated him mag 7.8, so more brilliant than the efemerides! Little coma with a brilliant middle. David...

A search of the archives shows that not all years are equal for Hind's variable. I was wondering if anyone had observed it recently. Last night in poor...
Hi Greg, My notes from February 2005 indicate that through a 28" scope Hind's Variable Nebual was quite faint and was best without a filter. I haven't had a...
