With my 24-inch...
At 200x; bright, nearly edge-on 4:1 N-S, ~6.5'x1.5'. Very asymmetric appearance with a brighter, elongated core, ~1.0'x0.5', which is oddly angled NNW-SSE to the major axis. A...
Hi, here's my observation from 11/8/2009: ngc 7640 is a galaxy in Andromeda : mag: 11.3 ; size: 8.1' x 1.7' ; elongated and rather faint ,brighter central area and mottled edges. I used a 10mm Radian...
I remember this galaxy as being somewhat disappointing in my 6" Newtonian telescope because I always hoped to see more of it than an oval glow. With my 20" from Southern France 8 years ago I logged:...
NGC 7640 as perceived by A.L. with a 13" at 70x back in 1991: "Mottled glow amongst faint stars. Elongated. Hard to see where it ends." The mottledness is due to the AI's description of star forming...
Thanks, Akarsh, for mentioning "An Atlas of Local Group Galaxies". Since this book is not commonly used, here’s part of the labeled image of PegDIG with A1, A2 (two OB associations), C1 (cluster),...
Thanks for your research, Victor. I went to put it on my list of objects to observe last night when your mentioning LBN 640 brought back a memory. I then grabbed Stoyan's Interstellarum Deep Sky...
With Jimi Lowrey's 48" in 2016 October:
Beautiful object. A bright core lies inside an elongated ring. The hole (gap between core and ring) on the eastern side is larger and more prominent than...
Excellent information, Steve! BTW, "An Atlas of Local Group Galaxies" by Paul Hodge, Brooke Skelton and Joy Ashizawa designates a brightening just east of the core as "C1" and calls it an open...
I was one of the observers who saw the halo around the star. There was definitely a brighter halo around V814 Her than other stars that "appeared" roughly similar in brightness. I put appeared in...
Wonderful pick, Steve. And I enjoyed reading what you were able to piece together about its discover(s).
While not as bright as Akarsh's Local Group pick from a few weeks back, this one is still...
I should probably have mentioned that 1° due west of PegDIG is the galaxy cluster Abell (AGC) 2593 with cD member NGC 7649. Most of the other galaxies are very small and fairly dim (V = 15.0-15.6),...
I had an entry with my old 16-inch.
I wrote: very sensitive to exit pupil - not visible with low power searching eyepiece and disappearing from 180x up, best magnification around 100x-129x...
I got an old observation and sketch with my 16-inch under very good skies in the High Alps back in 2005. I definitely had to revisit it with larger aperture.

This glow was a pleasant surprise, the one time I observed it in the night of 30 September 2021 in the French Alps (session / blog).
Truth be told, I doubted it could glimpse it at all in my 14"...
Seen twice with a 22". 337x "Star hopped from NGC-7653.Used Millenium and printout after that. Definite hazy glow next to 2 field stars. Worth a re-look."
Two years later same telescope, same...
Thanks Steve Gottlieb, for the HST image & an amazing list of post AGB objects. I will try & add as many as I can for the 12" scope.
Thanks Victor, for the response. Hopefully you didn't struggle...
The structure appeared more complex to me than a ring through Lowrey's 48-inch at 488x on 11/5/21:
Overall, bright, fairly large with a highly irregular appearance. The outer halo extended nearly...
Hi All,
I observed this galaxy a year ago on la Palma, herewith my observation note and sketch:
16" Sumerian Alkaid; Pentax XW 7mm at 259x
Immediately seen as quite large, bright and oval...
Can you give a more constructive reply?
With my 12" I have observed the disks of several stellar planetary nebulae so I know it is possible. Also TS states that two other observers confirmed their...
The Hubble image shows that there is a shell so there is a possibility that it can be observed visually. In that sense the Hubble pic can very well be used for planning observations.
A shell of 4"...
The problem with this "observation" is unfamiliarity with angular size and the true field of view in an eyepiece. In (visual) astronomy this is as basic a thing as understanding right ascension &...
Here's an HST image, which shows an irregular dust shell elongated N-S, though scattered light from the bright post-AGB star does seem the most likely cause.
The Torun catalogue of Galactic...
Hi Sudhash,
I took a look at the information you sent and I can not identify an extended, non-stellar object at the position of V814 Herculis. I am quite confident you observed a halo brought upon...
Hello all,
In my recent visit to Hanle (a Bortle 1 location in Ladakh, North India), a cold dry dessert at an elevation of 4300m, (32°47'N 78°58'E ), I tried to observe this Proto Planetary...
