M33 / NGC 598 – Triangulum Galaxy

First meeting with CMOS astrophotography camera. During first time I’ve collected the Light frames with the CMOS camera, nothing came of it. What I collected then was at best worth learning about its use, how to collecting photons with a CMOS camera, but it was not worth showing to public → trash. Trusted colleagues know what I am writing about.

Smarter about the knowledge gained from failure … the second attempt was already better, together with the signal, I also collected a huge amount of noise. It was impossible to correct it with the calibration files. As a result, I had to rely heavily on photo processing software to save what was possible to save. Picture shown below.

Science doesn’t go into the forest so by the third time it should be optimal – I hope.

I noticed that the CMOS camera for the astrophoto squeezes the unmodified camera with the range of captured colors. Yes, I know … the modified camera is much better than the unmodified one, but is it worse than the dedicated astrophoto camera? I believe it is, but only when I came into contact with the equipment and the whole process of processing the collected material by myself, only then I was able to “feel” the difference. I admit that personally for me, capturing photons with a CMOS camera is more difficult than using a photo camera.

About galaxy M33:

Is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy.

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.

Moon – just after full

The sky was interspersed with clouds. Once there were cirrus’s, sometimes they were cumulus clouds, but there were also windows between them to try to take a test the new equipment and photograph something. The tests were successful, but the atmosphere was waving. Moon on top.
