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 :)
sketch Cn 3-1: 27", 837x, no filter, Seeing II, NELM 7m0+ (Edelweißspitze, Austria)

sketch CN 1-5: 28", 843x, , Seeing II-III, NELM 7m5+...
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...
Hi all,
I have only a sketch that was made from binocular (35mm diameters, 12.5-times magnified) observations from Waikiki Beach, Honolulu, Hawaii from 2017:
Hello everybody!!!
It has been quite a while since I have been posting the last time... I haven't done much astronomy in the last 3 years, but now, I what to start up again. I started last autumn...
Did you know my homepage and the English written Abell project?
To make it short. I could see a glimpse of Abell 5 but no any sign of Abell 9.
To make it more detailed:
Abell 5
16", 100x, ,...
I copy my observing notes from my Abell project.
8", 47x, , NELM 6m5+
nothing visible without filter; with filter easy and direct vision glow around bright central star; north and east two other...
Hey y'all,
Just wondering, anyone ever catch Abell 5 and 9? Those two are the only two in the Abell Planetary catalogue that I have never successfully observed. However, I have not attempted...
My notes on this object are meager: I have only one observation from Texas Star Party 2014 when it was found and shown to me by young amateur astronomer Santhosh Surendra. I didn't even log whether...
I though I'd add that the first visual observation I'm aware of was made by Dana Patchick back in April 1982, just using an 8" f/6 reflector in southern California. I assume he was using a UHC or...
I can contribute a 4" observation from 2012, Hakos, Namibia (40x, 1.8° field).
I almost forgot to draw NGC 5139 on our first trip to the south. So I was in a hurry to get it done. And I managed to...
