M81 and M82 form part of the M81 Group, a grouping of galaxies located approximately 11.8MLy from Earth in the constellation of Ursa Major. A total of 34 galaxies have been identified as belonging to the group (see en.wikipedia.org/wiki/M81_Group#Members). M81 was discovered by Johann Elert Bode in 1774.

Revisiting the constellation of Orion in 2020.

This is a mosaic of 3 panels RGB comprising a stack of 120 exposures of 2 minutes each. Taken during 5 nights in 2018 and 2019 in rural Upper Austria with a Nikon D750 and a 135mm Sigma Art lens at f/3.5 and ISO 1600.

In November and December 2020 3 hours of H-Alpha data (45x 4 minutes at f/2.8 and ISO3200) were added for each panel. An Astronomik 12nm H-Alpha clip-in filter for Nikon DSLR was used. Tracking with Astrotrac; processed with Astro Pixel Processor, Starnet++ and Photoshop.

NGC 1499 es una nebulosa de emisión en la constelación de Perseo a 1000 años luz de distancia. Se encuentra al sur de la constelación, 36' al norte de Menchib (ξ Persei). Por su forma recibe también el nombre de nebulosa California, ya que recuerda el contorno de ese estado de Norteamérica. Aunque tiene 2,5º de longitud, debido a su bajo brillo superficial como mejor se la aprecia es en fotografías de larga exposición. A simple vista solo es posible observarla en noches especialmente oscuras.

El color rojo de la nebulosa es ante todo Hα (Hidrógeno alfa). Con una longitud de onda de 656,3 nm, esta luz proviene de átomos de hidrógeno en donde un electrón excitado del átomo regresa a un nivel de baja energía, liberándose un fotón de esa longitud de onda. Presumiblemente sea la antes citada Menchib, de tipo espectral O, la estrella responsable de su iluminación.1​

Fue descubierta en el año 1885 por Edward Emerson Barnard.

The Dumbbell Nebula is a planetary nebula and is in the constellation Vulpecula, It’s ~1227 light years away from us. “Plantetary nebubla” is kind of a misnomer because it doesn’t have anything to do with planets, the gasses and colors come from a star that has shed its outer layers. If you squint or zoom in, you can see the white dwarf star in the middle. Charles Messier first noted it in his catalog of objects in the night sky as Messier Object 27 in 1764. The Dumbbell Nebula gets its name from English Astronomer John Herchel, who thought its shape resembled a dumbbell. - You can view this object with a small telescope, or even binoculars.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Nikkor 500mm f/4 P Ai-s on a ADM dovetail rail on the top of my optical tube. For this I used a 1.4x teleconverter making the focal length 700mm at f/8. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop. I stretched the 32 bit file and used Gradient XT on the image. I then made it a 16 bit file and stretched in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I did mask the nebula and bring some color out on it, while not adding the color to the stars and deep space. I then using my skillset and relyed on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.

I imaged the Pleiades about a month ago. I used my 300mm lens. After getting some time on the Dumbbell Nebula, I took off the teleconverter and shot this target again with a longer focal length than I had before. I also used ISO 3200 and f/5.6 to bring out those diffraction spikes, which I think look really cool.

The Triangulum Galaxy is the third largest member of the Local Group and lies about 2.73 million light-years from Earth.

Image taken in the course of september 2020 at the remote observatory at the E-Eye site in Spain.
The image is composed of 319*180 seconds with a ZWO ASI-2600MC using a Takahashi Epsilon 180 ED Astrograph, riding on a Paramount ME II.

IC 342 is an intermediate spiral galaxy located in the constellation of Camelopardalis. Despite its size and actual brightness, its location in dusty areas near the galactic equator makes it difficult to observe, leading to the nickname "The Hidden Galaxy". If the galaxy were not obscured, it would be visible to the naked eye. The dust makes it difficult to determine its precise distance, modern estimates range from about 7 million to 11 million light years. Imaged over 2 nights, the 25th and 26th of September 2020.

NGC 2174 and NGC 2175

First image using PixInsight to process. I'm kind of stunned in that I think I'm done after just 1 hour and 10 minutes of data!

Also used Topaz Denoise AI to finish it up.

Here is my best effort in Photoshop: flic.kr/p/2jW3stJ

Here is my 3rd. image taken on the 14th. October with an ASI 120 mono ccd. It is interesting to compare these 3 images taken with 3 different cameras.

NGC 253 (also known as the Sculptor Galaxy, the Silver Coin Galaxy, the Silver Dollar Galaxy, and Caldwell 65) is an intermediate spiral galaxy in the constellation Sculptor. At declination -25 I had thought that this would be too low for me to capture over the walls of my observatory in Spain, but decided to give it a try. I'm delighted to say that I was wrong- although capturing through so much unstable atmosphere was a challenge. I think this is such a handsome galaxy.
