Compared to amateur telescopes, it is literally a wider look with the 200 [mm], F 2.8 lens at a group of objects in the Bernard’s Loop. However the loop itself is not visible on picture (caught small piece in the lower left corner – red cloud), and the main subject of the photo are objects, like the well known M42 nebula in Orion. Next to left NGC 1977 – The Running Man with his small group of stars.

M42 / NGC 1976 – Great Nebula in Orion

M42 – Great Nebula in Orion – Also known as NGC 1976. This is the brightest nebula on the sky. It is located in the Orion constellation, south direction from Orion belt. The diameter of the nebula is 30 light years. The distance from Earth is 1344 thousand light years.

With this photo, I’ve tested my Mgen II Lacerta autoguider and in my opinion it did a very good job.

Orion Nebula (M42 or NGC 1976)

Farewell to Orion – my colours interpretations.

Winter is practically gone. Orion is almost no longer visible at night. We’ll see him again in late autumn. It will again become one of the most interesting places in the night sky to photograph.

TheOrion Nebula (M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

Wielka Mgławica w Orionie (M42 / NGC 1976) - moja interpretacja barw

Photos taken near Bielsko-Biała in two sessions at 17 and 24th of March 2020.

I have slightly improved the colors in both previous pictures.I have added the third photo, it’s only stack plus a bit of background noise reduction, without heavy processing to bring all out everything what is possible, as in the previous two photos. I’m starting to be convince myself, that the last photo is probably the best.

M42 (NGC 1976) – Great Nebula in Orion

Image processing improvement skills in progress. Below you can see a photo for comparison, that it is really worth improving own skills in image processing and it does not necessarily have to be done with paid PixInside, which will do 80% of the work automatically for the user. You can do the whole process yourself and acquire new skills. Important itself is that, the picture processed has a reflected “face” of the author, which is not meaningless in today’s world.

Interesting fact – At that time, when I was catching photons, I didn’t do any FLAT frame. Common opinion says that flat frames should be done in the same session as light frames. Making the necessary flat frames at a different time (the configuration of the entire equipment setting is different from the equipment configuration for the light frames made) will cause you to fail.

Naturally I am very inquisitive person and I did an experiment. I didn’t have a flat for lights done earlier, so I did flat frames with same ISO like light frames at 1st August this year at the PTMA meeting in Zwardoń. I remembered that my camera frame position was relative to the tube in only two positions. Perpendicular to the length of the tube or parallel. I made flat frames for both positions and used them one by one position successively in the stacking process. I saw that the flat frames matched almost perfectly with light frames. The difference between old image processed without flat can be clearly seen in the pictures below with flat frame.

On the left, photo taken in April this year and on the right, processed at 09.12.2019 + flats made at 1st August 2019.

Does my experiment contradict popular opinion? In my opinion, yes.
My advice: if you do not have flat frames and you have collected great material earlier, then make a flat frames. Time and place is not important. It is important that the equipment should be the same and the configuration of the layout and position should be only close to how the light frames were made.

At that time, I was testing the autoguider Mgen Lacerta on this nebula, and as you can see it did a good job. At that time I did not have a coma corrector (optical defect correction) as seen at the edges of the photo. My NEQ6Pro mount was still working on gears (original solution).

For my new friends on FB, for information:
