Image Description and Details : Messier 82 is the very first galaxy I was able to observe with the naked eye with my old telescope: a C9.25 EDGE HD on a Losmandy G11 Gemini mount. This was in early January 2014, when the supernova SN 2014J was visible. It was also the first galaxy I photographed in May 2017. So it was a great pleasure to have been able to process the data of this galaxy from a much more ambitious setup.

Messier 82 (the Cigar Galaxy) is a starburst galaxy, meaning that it has an exceptional rate of star creation compared to most galaxies. It’s located approximately 12 million light-years away in the constellation of Ursa Major. About five times brighter than the Milky Way, the intense star formation activity was triggered by an interaction with the neighboring galaxy M81.

Image Description and Details :

M106 galaxy dominates on this image. Also known as NGC 4258, M106 is about 80,000 light-years across and 23.5 million light-years away, the largest member of the Canes II galaxy group. For a far far away galaxy, the distance to M106 is well-known in part because it can be directly measured by tracking this galaxy's remarkable maser, or microwave laser emission. Very rare but naturally occurring, the maser emission is produced by water molecules in molecular clouds orbiting its active galactic nucleus.

The following galaxies can also be seen in the image - NGC4248 (bright at the left-bottom of the center), UGC7356 (above M106) and a pair of galaxies NGC4231 & NGC4232 (in the lower left corner of the full-size image). Beneath NGC4248 is also a cluster of distant little fuzzy galaxies.

What interesting is that this image reveals one of the two faint hydrogen jets inside M106 (2 o'clock from galaxy center).

Image Description and Details :

Consisting of 300 billion stars, the Andromeda galaxy M31 is considered the twin sister of our Galaxy. It is accompanied by two much smaller satellite galaxies, M32 and M110. The Andromeda Galaxy is the most distant object that can be seen without an instrument under good skies, at 2.5 million light years.

The Ha stands out all around the FOV and the Oiii shows quite well permeating the image.

Image Description and Details :

In the direction of the constellation of the Puppis there is this pair of open clusters cataloged by Charles Messier as M46 and M47. On closer inspection, in the direction of M46 there is a very small planetary nebula cataloged as NGC 2438, the remnant of a stellar explosion that left a white dwarf at its center. NGC 2438 is 2900 light years away from us and has an extension of "just" 4.5 light years.
