Copeland Septet
The Copeland Septet - or the poor man's Hubble Deep Field from the back garden
I’ve always wondered how “deep” I can see into the Universe with an amateur equipment, this image is the result of the experiment.
Leo is full of galaxies anyway, so I was hoping that other than the seven / eight members would be seen.
The end result was 38 galaxies for my astonishment and joy, some of which are so faint I didn't find them in any of the catalogs I know.
The limiting magnitude of the image is around 22.
The more I look at the picture, the more I realize how insignificant and little I am with the whole Planet Earth, so I rather stopped looking.
Equipment:
351*2 min light frames (=11,7h) in April 2020., 30 flat and bias (didn't need darks)
Scope: Celestron NexStar 8SE + f/6.3 reductor+ AVX GEM
Main camera: Starlight Xpress H9C + Optolong UV/IR cut filter+ Sequence Generator Pro
Guiding: Celestron Off-axis guider + Starlight Xpress Lodestar + PHD2
Bortle 5 sky
Processing: PixInsight and for the annotation: GIMP
Attached the original full picture and an annotated one as well.
Dear All, I wish you Very Happy Holidays in advance!!

Re: Copeland Septet
That's very well done capturing this faint galaxy group in such fine detail, Krisztian! As a lover of all blue things, I'm particularly happy that you managed to bring out the knotty bluish ring of NGC 3754! And of course, I love your portrait of NGC 3753 too, this weird edge-on spiral that seems to have suffered a "fracture" at one end of its disk, and it seems to be "spitting out" a diffuse tidal tail out of its gaping "mouth"!drbilbobaggins wrote: ↑Tue Dec 22, 2020 2:21 pm The Copeland Septet - or the poor man's Hubble Deep Field from the back garden

You have done a splendid job of capturing the delicate arms of barred spiral galaxy NGC 3746, too.
Again, that's a lovely picture. Welcome to Starship Asterisk*!

The day of the great conjunction finally arrived, and I was able to take this picture combining 4 different exposures in near IR light. Jupiter can be seen with its four main moons (Europa, Ganymede just starting to transit Jupiter, Io and Callisto) and below Saturn Titan can be seen. Taken from Monterrey, Mexico.

During the past week I was able to witness this amazing phenomenon, the Total Solar Eclipse. Between 2:06 minutes of totality, I was able to take some captures using my Newtonian telescope and my reflex camera. I share with you some photos taken at the end.
Hope you like it.

Abell 78: A planetary nebula with 'born-again' progenitor star
Copyright: Luca Marinelli
Location: Schenectady, NY
Abell 78 (PK 081-14.1, PN G 081.2-14.9) is a planetary nebula in the constellation Cygnus discovered in 1966 by George Abell. It spans 1.4 light years in diameter and is located roughly 5,300 light years away. Planetary nebulae are formed by the expanding gas shell around a white dwarf progenitor star, the late-stage evolutionary phase of small to medium size stars, not massive enough to explode into a supernova. Having exhausted the nuclear fuel in their cores, these stars collapse to become dense white dwarfs.
What is unusual about the white dwarf star visible at the center of Abell 78 is that it has reignited and come back to life, hence the moniker 'born-again star'. Only a handful of such born-again stars have been discovered. Although nuclear burning of hydrogen and helium had stopped in the core of the dying star, some of the star's outer layers became so dense that fusion of helium resumed there. The renewed nuclear activity started another much faster stellar wind, blowing more material away. The interplay between the old and new outflows has shaped the cloud's complex structure.
Abell 78 is a small planetary nebula (113"x88"). In spite of its reasonable brightness, I collected a significant amount of data to allow me to stretch the background and select low-FWHM subs to highlight the intricate structure of this small DSO.

This photo presents the celestial path of planet Venus on the Eastern sky between end of June and the middle of December capturing with a wide-field and a telephoto lens near Mogyoród, Hungary. The pictures were taken at the time when the Sun was located exactly seven degrees below the horizon.
At the bottom of the photo I tried to demonstrate the change of the visible size and phase of Venus as it slowly turned from crescent to a disk.

STROTTNER-DRECHSLER 1 / COCO'S NEBULA
StDr1 (PNG 185.1+-0.9) is a new spectrum confirmed planetary nebula (PN) in the constellation of Taurus.
The PN was discovered in October 2019 by the French-German research team Marcel Drechsler and Xavier Strottner.
The potential central star of StDr 1 is located at coordinates 05:53:48.86 +24:02:41.45.
If this star is used as a calculation basis, then StDr 1 is located at a distance of 9203 light years from Earth.
For a PN at this distance, it is unusually bright.
In addition, this photo was the first to detect an annular H-alpha structure around StDr 1.

Re: Submissions: 2020 December
WIth the Great Conjunction observed widely, I was struck by the image taken by the Lunar Reconnaissance Orbiter (http://lroc.sese.asu.edu/posts/1174)- it looked more -or-less like my own image(s) despite the much more expensive equipment and exotic location.
I realized that the baseline of about 245,000 miles should make for a noticeable 3-D effect by combining the Earth-based and lunar images. My image (the left one in the pair) is a 1/30sec exposure using a C-5 (1250mm f.l.) taken in Ames, IA at 23:30UTC on 12/21.
The two images were taken about 2 hours 15m apart (LRO at 21:15UTC, mine at 23:30UTC) - in that time, Jupiter moved about twice its own diameter (along the plane of its rings) to the East with respect to Saturn. So to do the combination, I had to 'adjust' my image by moving Jupiter to where it was at 21:15UTC. Jupiter appears larger in my image as it is a bit overexposed and affected by processing that clarified Saturn's image.
The 3D pair is designed to be viewed cross-eyed (I can provide a parallel-view or anaglyph [red-blue] version if needed. Jupiter really pops out. If the LRO image had shown the moons of Jupiter or background stars, that would have been better...

Re: Submissions: 2020 December
Hi,
I would like to submit my M1 image, that I've taken around mid December 2020.
Rig details:
Mount: Avalon Instruments Linear Fast Reverse
OTA: Celestron EdgeHD 8” SCT, reduced to 1500mm at F7
Camera: ZWO ASI1600MM Pro + Astronomik 6nm narrowband filters
Autoguiding: ZWO ASI290MM + ZWO OAG
Integration: 100/112/110 S2/Ha/O3 frames with 5 minutes exposure time. ~27 hours total

The first entry in the Messier catalog is also known as the Crab Nebula. The supernova remnant is in the constellation of Taurus. It lies 6,500 light-years from Earth, and measures about 13 light-years across.
The analysis of early photographs of the nebula taken years apart revealed that it was expanding. Tracing the expansion back revealed that the nebula must have become visible on Earth about 900 years before.
Historical records revealed that a new star bright enough to be seen in the daytime had been recorded in the same part of the sky by Chinese astronomers on 4 July 1054. The supernova was visible to the naked eye for about two years. It is expanding at a rate of about 1,500 kilometers per second, or 0.5% of the speed of light. (Source: Wikipedia)
Humanity has come a long way. I can imagine the look on the faces of the people who traced back this supernova remnant to an explosion recorded in our relatively recent history. I wonder if Betelgeuse will give us a similar experience in our lifetime.
Clear Skies,
Michel Makhlouta
