My second project with the new ZWO ASI6200M Pro – this time with 2x2 binning for smaller sub size (30 MB vs 120 MB) and higher SNR. The 2X loss of resolutions is not really noticeable. (-:

Camera gain was fixed at 100 with 60s Luminance subs and 300s RGB and Ha subs. Several hours of luminance subs were discarded in favor of the best FWHM.

Ha was applies over the LRGB with a starless screened overlay to help highlight the vigorous star-forming regions.

Fortunately the great positioning of IC10 allowed me to capture lots of subs – 9 hours per day from 8:30 PM to 5:30 AM over 3 days. Before that we had 8 days of high-altitude smoke from the CA fires. Skies were very dark, but just a handful of visible stars.

"Lurking behind dust and stars near the plane of our Milky Way Galaxy, IC 10 is a mere 2.3 million light-years distant.

Even though its light is dimmed by intervening dust, the irregular dwarf galaxy still shows off vigorous star-forming regions that shine with a telltale reddish glow.

IC 10 is the closest known starburst galaxy. Compared to other Local Group galaxies, IC 10 has a large population of newly formed stars that are massive and intrinsically very bright, including a luminous X-ray binary star system thought to contain a black hole.

Located within the boundaries of the northern constellation Cassiopeia, IC 10 is about 5,000 light-years across."

Thank you for all your galaxy images! I really appreciate them!

I just spent a lot of time identifying all the bright stars and nebulas in this fabulous picture! Thank you!

Ann

thank you very much.
The mosaic grows little by little. To this day, he already has 25 photographs and it looks like this.
A greeting.

The Subaru!

I shot some exposures on M45, also known as the Pleiades/Seven Sisters/Subaru. They’re like a box of jewels in the northern sky and easily visible to the naked eye and probably the best looking star cluster visible from earth. Imagine the dusty cloud of reflection nebula next time you see them. Easily visible rising in the east after dark these days.

The dusty nebula are clouds being lit up by the star cluster as it moves through space. So it will change and move over v long tine periods. They’re really close by galactic standard at a mere 440 light years. Perhaps one day we’ll mount an expedition to visit which may be possible using nano robots travelling at neat light speed. Yes that’s a thing!

I stretched the processing quite far to try and highlight the surrounding dark dust but it’s extremely faint. I suspect adding more exposure will help bring them out.

This is just under 4 hours of LRGB taken over 2 nights. It’s a mix of 3 and 1 minute exposures.

Luminance- 50 minutes
Red - 62 minutes
Green - 60 minutes
Blue - 67 minutes
