NGC 6752
Bernard Miller
Hi,
This is NGC 6752. It is globular cluster about 13,000 light years away in the constellation Pavo. It is the third brightest globular cluster in the sky behind Omega Centauri and 47 Tucanae. It holds over 100,000 stars in a sphere about 100 light years in diameter.
Comments and suggestion appreciated.

Leo Triplet 4 panel mosaic
Madhup Rathi
A 4 panel mosaic. Each set was taken for 14 luminance image of 20 minutes each and supplemented with 7 images each of 20 minutes of each color, thereby accumulating data for each part of the 4-part panel for 8 hours, for a total of 32 hours on this image.

Madhup,
Excellent detail and composition.
The color looks a little purple?

Madhup,
I noticed after posting that most of your images are biased to blue/purple. I’m guessing that is your style.
Thanks for posting,

Really beautiful image. Great job on the mosaic. Not a seam anywhere. You would never know it is not a single image.

Comet 68P/Klemola
Dan Crowson
Comet 68P/Klemola was mentioned as being visible and brighter than 11th magnitude with a bright moon. Unfortunately, this was a mistake or a short-lived outburst. Photometry on the exposures that make up this short video show it to be at magnitude 15.3.
68P/Klemola 2019-09-18 - Animas, NM 03:10:07 - 03:39:24 UTC Astro-Tech AT12RCT - SBIG STF-8300M Luminance: 15x120s binned 2x2

Sharpless 141 (LBN 509) is a faint nebula located approximately 23,000 light-years away in Cepheus. The stars on the left side of the nebula are cataloged as open cluster Teutsch 76
Ha – 24x1800s – 720 minutes – binned 1x1 RGB – 8x300s – 40 minutes each – binned 2x2
840 minutes total exposure – 14 hours
Imaged over five nights in September, 2017 and September and October, 2018 at Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

Brian,
It is not well placed for us. I don’t think I can get low enough and when not in astronomical darkness. I’ll probably try, though. J

Sh2-170
Gregg Ruppel
Hi all:
The monsoons haven't been kind to us here in the desert SW (lots of night time clouds). I was able to get a little over 10 hours worth of data on Sh2-170, an emission nebula in Cassiopeia: http://www.greggsastronomy.com/IMAGES/Sh2-170_LHaRGB.jpg The open cluster Stock 18 makes up some of the stars within the borders of the nebula. Image data here: http://www.greggsastronomy.com/Sh2-170.html There is also a faint, irregular planetary nebula in the upper left corner of the FOV, PK 118+2.1: http://www.greggsastronomy.com/IMAGES/PK118+2_1.jpg (stretched and enlarged 1.3X) -- Clear skies, Gregg Visit my astronomy & astrophotography site http://www.greggsastronomy.com/

Hello all,
A 4 panel mosaic. Each set was taken for a total of 13 images of Luminance of 0 minutes each; 13 images of Ha (Hydrogen Alpha) of 20 minutes each; 7 images of each color of 5 minutes each for each panel. Making it a total of 33 hours on the image. Stacked and Mosaiced in Maxim DL and processed in Pixinsight.

NGC 247 - The Needle's Eye Galaxy
Bernard Miller
Hi,
This is NGC 247, also known as the Needle’s Eye Galaxy. It is an intermediate spiral galaxy about 11 million light years away in the constellation Cetus. It is noticeable for the large void area on the left side of the spiral disk, which is why it has its name. The four galaxies in the lower left of the image are known as Burbidge's Chain. These galaxies are about 300 million light years away. The two leftmost galaxies are interacting and you can see fait tidal streams between them.
Comments and suggestion appreciated.

Thanks,
Bernard
