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...

I was observing with Akarsh this week and was looking at my old Uranometria and came across a...
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...
For the same three Cannon planetaries, here are my notes using an 8" and a 14.5". Cannon 1-1, 1-3 and 1-4 are between -44° and -49° declination, so may be too far south for many here. I have some...
Hello Folks,
here are three sketches from Objects that i visit last August with my 21 inch Dobson. NGC 6207 is a galaxie in the near of M13. NGC 6974 (E) and NGC 6995 (H) are little nebulas in...
Hi, here's my observations of 3 Cannon planetaries : Cannon 3-1 in Ophiuchus ; mag: 13.5 ; size: 6" ; small, round and dim. I used a 4mm Radian at 436x
Cannon 2-1in Scorpius ; mag:12.2 size:2" ;...
Google found three more entries Mark :)

You are correct that these nebulae were discovered by Annie Cannon from objective prism surveys with the 24" in Peru. They were published (in the case of Cn 2-1) in a paper by Harlow Shapley in the...
Good comment, I tried to keep it consistent to make the blue mag with a "b" and if truly visual with a "v". Otherwise nothing. I take whatever the source give.
In my many decades of observing,...
My only record of this object is through my 25x100 binoculars from Anza Borrego desert California, although I have seen it at least once in 2005 or 2006 with my then 8" f/8 telescope.
"Beautiful!...
I looked up some of the group with an alternate name and it appears the listed mag might be a mix between the blue mag and visual depending on the object
Hi Alvin,
I envy your dark skies but will try and see how it goes on a couple of the brighter and well placed group for me at 40 degrees north. Are the brightest member magnitudes listed the...
These are some of my notes through a variety of apertures. The sites and observing conditions also varied significantly.
48": at 375x; highly resolved cluster with chains of brighter stars,...
With my old 6" Newtonian telescope from southern France in 2008 I saw this globular cluster in my 50 mm finder. At 64x a large, not quite round glow with one side sticking out a bit. At 146x a few...
Hi, here's my observation from 4/4/2011: Ngc 5466 globular cluster in Bootes : mag: 9.2 ; size:11' ; fairly large but dim ; using averted vision and lots of patience, more stars come into view. I...
With a 10" at 45x: "Very faint, yet broad and almost square in shape."
With a 20" at 192 & 272x: "Almost like an open cluster, possible a Class XII. No concentration towards the center. A scattering...
Amazing, indeed, that this one hasn't made it to OotW before..!
My most recent observation for this globular was less that 2 months ago, the early morning of 2 April in France (session / blog). I...
Whereas I've seen NGC 4388 way many times because of it being part of the Markarian Chain nonet (the 9 galaxies typically seen in a 31mm Nagler FOV on most 18 inchers), I never have observed it...
