In December 2023, Spanish Amateur Astronomer AleixRoig discovered a new emission nebula in the outer regions of Messier 33 DOI 10.3847/2515-5172/ad12d1]. He named is "Roig1 Prades Sky".

Hi Uwe,
Wow, congratulations! And thank you for suggesting this as a target for the 20" class. I'll give it a try.
By the way, have you also tried Maasewerd 2 Nebula, which can easily be seen...
Here are my observations of the NGC 507 group. My descriptions are decidedly shorter than Steve's! I used my 20" in the night of Sept 8, 2016, from Southern France.
NGC 499: At 320x very bright,...
Hi All, I observed this group in 2020 in France, here is my note and drawing from that night:
NGC 507 and NGC 508 are in the center of the group, pretty close to each other. The halo enveloping...
These members of the NGC 507 group were all observed using my 24-inch on the same night in October 2013 at a California star party.
UGC 862 = PGC 4810

NGC 507, with an 18" at 332x: "Fairly bright galaxy near a magnitude 9 star. The center is fairly bright and condensed. Adjacent is NGC-504 and 508."
NGC 508: "N of NGC-507. Softer and fainter than...
I recorded several observations.
Smallest one was with a 99mm spotting scope. While I missed the galaxy under soso conditions, NGC 7640 was clearly visible under good transparency as a ghostly 3:1...
A little over 2 years ago I posted the text above in reply to this OotW.
Today, the mystery of components A & B of the "double star" Jonckheere 475 has become clearer to me, hence this post.

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"...
