M33 - Triangulum Galaxy

The Triangulum Galaxy is approximately 3 million light years from Earth. It is approximately 50,000 light-years across and is the third largest member of the Local Group of galaxies, which also includes the Milky Way and the Andromeda Galaxy. It may be gravitationally bound to the Andromeda galaxy. It is one of the most distant objects that can be observed without the help of a telescope. It is an object with a hazy appearance, and its visibility is significantly affected by even a small amount of light pollution. It is observable only in a dark sky outside of rural or suburban lighting and is among the reference objects of the Bortle light pollution scale.

M33 has been a very difficult object for me for a long time, which I have tried many times. There has always been a problem with point stars, even with the very sensitive G1-0300 camera. Older attempts turned out even worse. This image is the result of only 15 exposures at 600 seconds, which is quite a few for such a faint object. The smaller number of images is because M33 was photographed during a test of the new telescope and I tried more objects during the night.
