GLOBULAR STAR CLUSTER MESSIER 4 (NGC 6121)
Messier 4 (NGC 6121) is a globular cluster of stars in the constellation Scorpio, discovered by Jean-Philippe de Chéseaux in 1745 or 1746.
The cluster is at a distance of just 7,200 light-years from Earth, considered the closest globular cluster to Earth until 2007, when the distance of the FSR 1767 cluster was estimated to be just 4,900 light-years from Earth.

Re: Submissions: 2021 December
Venus and Moon
Recently, Venus is getting closer to the earth, and its apparent diameter is getting larger and larger. This photo was taken on December 7 with the same focal length of Venus and Crescent Moon. The apparent diameters of Venus and Moon are 43.0" and 32'55.7”, respectively. That is to say, the moon looks about 46 times the size of Venus. I copied the images of Venus and placed them in a row on the diameter of the moon. Just 46 Venus images are needed!
Equipment:Canon EOS 600D + SIGMA 60-600mm F4.5-6.3 S DG OS HSM Sports
Post-production:Use PowerPoint to copy the Venus images and arrange them in a row on the diameter of the moon, and compare their sizes.
Location : Taipei, Taiwan
Time:Dec 7, 2021

Southwest lunar limb
Southwest lunar limb by Tom Glenn, on Flickr
This image shows the southwest lunar limb captured under an extremely favorable libration. The South Pole is near the top of the image and the infrequently observed craters Drygalski and Hausen are located along the limb, with many prominent craters in deep shadow along the sunset terminator, including Longomontanus at the bottom. Image taken November 28, 2021 at 13:45UT from San Diego, CA, with a C9.25 Edge HD telescope and ASI183mm camera with 610nm red long pass filter.

In this brief video, Comet C/2021 A1 (Leonard) can be seen cruising by a background galaxy, NGC 5523, which I refer to as the "Baby Whale" since to me it resembles NGC 4631.
Captured in the early morning hours of 05-Dec-2021, the exposure data appear below:
Mount: Orion HDX110 German equatorial mount controlled by TSXPro (Software Bisque) via EQASCOM
Telescope: Celestron RASA 11 V2. 11" Rowe-Ackermann Schmidt Astrograph, 620mm FL, f/2.2
Imaging camera: ZWO ASI2600MC Pro. Gain 100; Offset 21; Filters: Optolong L-Pro.
Image capture scale: AS/P=1.237" (i.e., unbinned). Resized to 33% for display.
Image capture software: Software Bisque TSXPro Camera Addon.
Exposures: 25 @ 60s, interval 60s, beginning 12/05/2021 04:58:31am MST.
Image Position Angle: 0° 44' from north through east
Center RA (2000.0): 14h 10m 57.97s; Center Dec (2000.0): +25° 39' 11.3" at approx 05:39am.
Calibration: 16 bias frames, 13 darks, 9 flat frames; Autoguided.
Guide camera: ZWO ASI120MM Mini. Autoguide software: PHD2 Guiding 2.6.10dev2. Tracking: ~0.49"-0.52" Total RMS.

C/2021 Leonard @ Baia di Portonovo by Andrea Amici - Andrystix
Here is my first and only attempt at Comet Leonard!
It was from the end of November that I was looking for the ideal weather conditions, but unfortunately it never stopped raining and the sky was always overcast.
I had almost lost hope, but this morning (Friday 10 December) after I woke up at 3.45 AM, I was finally able to take the shot I so wanted to do.
Miraculously the conditions were optimal and Leonard's magnitude was 4.85 (considering the air masses).
I was able to shoot until around 6 AM and eventually I also captured a small thunderstorm along with the twilight lights of dawn.
Nikon D750 modded, AF-S NIKKOR 70-200mm f/2.8G ED VR II
Panorama 3 blocks @ 70mm: landscape (1x13sec, ISO 2540, f/5.6), sky (1x20sec, ISO 3200, f/2.8), Leonard (85x20sec, ISO 3200, f/2.8 + 45 dark frames, bias, flats)

Hi Ann,
The first process was minimal and no sharpening so it would look more natural. Second process involving aggressive taming of the core and sharpening. Third process was less aggressive than second process. The sharpening created minor side effects. It created halos around the companion galaxies at left side and a little bit at right side but made M31 look pretty darn good.

Merope. KG Observatory, Julian, CA.
I was curious on how the 24" might capture Pleiades. We'll here's one of the sisters.
"In Greek mythology, Merope is one of the seven Pleiades, daughters of Atlas and Pleione. Pleione, their mother, is the daughter of Oceanus and Tethys and is the protector of sailors. Their transformation into the star cluster known as the Pleiades is the subject of various myths."

Note the perfect colors of the comet itself. There is the green coma, of course, and the reddish color of the brightest part of the tail, but then the the tail turns into a muted cyan color. Note how the background sky sparkles with stars of many different colors. Note the long indigo cloud bank, lit up by the brooding red reflections of a thunderstorm. Note how the shape of the comet is mirrored by the shape and direction of the shimmering light cones on the water, reflecting bright lights near buildings on the shoreline of the bay. Note how the shape of the bay and the tree sticking up at lower left adds to the exquisite composition of the image. Note how the brownish coppery and dull green hues of the vegetation adds to the rich palette of muted colors in this image.
I love it!

The colors are saturated, and I love it. Lambda Orionis, Meissa, is the bluest-looking star that I have ever seen through a telescope, so I love the fact that its blue color is brought out here. I love the elegant line of bluish stars culminating in Meissa, and I love the large red Lambda Orionis nebula, ionized by O8-type giant star Meissa itself.

The colors are saturated, and I love it. Lambda Orionis, Meissa, is the bluest-looking star that I have ever seen through a telescope, so I love the fact that its blue color is brought out here. I love the elegant line of bluish stars culminating in Meissa, and I love the large red Lambda Orionis nebula, ionized by O8-type giant star Meissa itself.
Ann
All the best.
