Hi Scott I enjoyed your OOTW. I am on the road traveling to GSSP. I am looking forward to trying your object with the 48” when I get back home in Texas.
Great write-up, Scott, and I appreciate all the research and links you've provided! Hopefully, if any others split this Herbig Ae-Herbig Ae binary they'll post the observation.
Hi, here's my observation from 4/4/2011: Ngc 3511 and Ngc 3513 galaxy pair in Crater ; Ngc 3511 is mag.11.5 and elongated with many bright knots . Ngc 3513 is 12th mag. and round and diffuse. I used...
Hi All,
Herewith a selection of 14 planetary nebulae, all sketched in Namibia with a 16" (Martini) dobson.
Very interesting to compare and seeing how different these objecst are!

With my old self-made 6" Newtonian telescope I observed these nebulae on August 5, 2005, from Southern France. I observed it with a 40 mm eye piece which IIRC was a Plössl eye piece so with a...
With a pair of 10x50 binoculars: "Both B-142 & B-143 are in the same field of binoculars. Opacity = 3 (B-143), Opacity = 4 (B-142). Relatively blank but not totally black. West of Altair."

I'm excited to post about...
It's a bit surprising to me that none of the later visual observers (after William Herschel) who might have taken a look resolved the pair. In any case, it wasn't reported so we're left with a...
Here is my observation with Jimi:
At 610x, I was able to easily detect both NGC galaxies. The tidal stream going northwest was a vague sensation and for some reason seemed much brighter around due...
I can contribute a sketch through the 27-inch. Under soso transparency but good seeing some structures could be resolved but not tidal streamers were visible.

Nice object.
As I told Dragan that I'm compiling all of my 2007 to 2019 observations from my notebook to spreadsheet, I ran across my notes for this object.
I'll eventually upload the notes...

To finish my post, Annie Jump Cannon also discovered several compact emission nebulae (even an extra-galactic PN) in the SMC and LMC on objective prism plates taken at Bloemfontein with the 24-inch...
