105/610mm apo, 47x
Small, faint but obvious, some brightening toward the center.
130/819mm apo
37x: Fairly small and faint, but grows brighter toward the center.
117x: A pair of extremely faint...
The paper being submitted to Nature says:
The total magnitude of NGC1052–DF2 is V606 = −15.4, and the total luminosity is Lv = 1.1x10^8 Lsun
I almost sent this yesterday, but I'm visiting relatives and haven't had a chance to read the relevant papers. So, I have no idea whether Jimi could see this, but it shows in MegaStar. This gained...
With all the hoopla about Nova Sco 1437, has anyone been able to see its nebula?

PK 343-0 1
PN G343.3-0.6
RA: 17h 01.467m
Dec: -43° 05.92'
Size: 2.0'
George Jacoby suggests that it may be a very dense, dusty object so that the usual ionization lines aren't appearing (or not very strongly). He also suggests that even with a spectrum sometimes you...
I can see at least the core of IC 1296 in my 14.5-inch under good conditions, but its a tough catch.
For the past 15 years, Ive been trying to see the planetary nebula PN G 089.3-02.2 (Minkowski 1-77, PK 89-2 1). It looks like a star through everything at any power. Well, there were a couple...
254/1494mm Newt
22mm Nagler: Dolidze 8 is a 5′ × 2′ collection of 11 fairly bright to faint stars, elongated SE-NW with nebulosity engulfing 3 of the brightest stars, which lie in the NW part of the...
This is with a 15-inch Obsession at 247x.2230
I observed these several years ago, and have pulled their log cards for articles every time I do the area. But I always wondered if anybody would even care. At the moment, they are tentatively...
9-23-03 254/1494mm Newt
22mm Nagler: I could not find this without a filter, but it popped right out when I added an OIII. Once identified, I removed the filter and could faintly see the object...
Here's my sketch from a few years ago.

Here's a sketch of NGC 7027 through my 15-inch at 345x.
That was the 105mm protoype of the AP Traveler, which is what pretty much everything in Celestial Sampler was done with unless otherwise stated. Thanks for the kind words, Sue
Has anyone observed Sh 2-175 in Cassiopeia in recent history? A gentleman wrote to me saying that although this was visible to him in the past, he can no longer spot it in small or large scopes, at...
For what it's worth, NOMAD give a visual magnitude of 16.6.

Preston,
Sorry for the late reply.
I covered Leo I when I was writing Small Scope Sampler, hence it's in the first book, Celestial Sampler. Here's the text:
Next we'll move to the end of...
Victor,
Thank you kindly for the observations. I retrieved images of the diamond in some non-visual wavelengths where the stars aren't so overexposed and saw nothing near the westernmost star nor...
Mark,
MegaStar often places a double star marker on the wrong star in a cluster. I suspect they used truncated coordinates, whatever WDS listed back then, and then picked the cloest star of about...
Folks,
At one of our club's star parties this week, someone asked me about the star cluster NGC 2218 in Auriga. His SkySafari has, word for word, the description in the Night Sky Observer's...
The center of Maffei 1 is visible in a 105mm scope at 87x with averted vision.

Use the Aladin Sky Atlas online or download it to your computer. Call up an image of the area of interest. Choose VizieR -> Photometry to see catalogs that cover the area. Overlay catalogs onto...
Mark,
I've logged Abell 4 on two occasions, with a 10-inch. Here are the observations.
