M100/NGC4321 the mirror galaxy, approx 55 million light years away. Haven't found out what the cigar shaped galaxy is down to the right of M100. I think it is NGC 4312 which is about the same distance from Earth as M100. 40 mins of 30 second exposures. Rain forecast for next week, with global warming we will soon be planting rice here!

Here you go Harry. I did some research for you. All Galaxies visible in your image are marked. Most are identified and catalogued, but others with the question marks are identified as Galaxies but not yet catalogued with a name or number. There are several hundred others in the maps I used that were just too faint for us to image (beyond Mag 18). The good news is that you have captured Galaxies down to Mag 17 Excellent work!!! Here's an animation of what you captured!
The Identifiers are on the left side of each object except M100 (The Full size image may take a few seconds to load)

Just to show how many Galaxies there are in Coma, here's an image of a very small area near M100 showing the un-catalogued objects recognised as Galaxies according to Deep Sky Mapping. I only marked the ones that didn't show up in your image (they wouldn't show up in most peoples images ) The ones with blue circles did show up in yours and I marked them on your image

That is just brilliant Ken, I watched the image building up and thought the objects that just looked like smudges could be other more faint galaxies. My first attempt I had the filter on, which with thin cloud came up with failed exposures. With the filter off and with clear sky no Moon and M100 getting higher it worked well. Seestar pointing away from my worst light pollution helped.
Thanks Ken, much appreciated.

M101 pinwheel galaxy from last night. 52 x 30 second exposures. Processed with the Seestar app this time. Unprocessed image
The biggest plus about the Seestar is being able to set up quickly. and leave it to it once it starts imaging.

Fantastic capture of the Galaxy Harry. I don't know if you have PhotoShop, but if you do, open your photos in the 'Camera Raw' filter and do a Colour Noise adjustment. It only changes the colour in the Noise, not the object or stars. Here's the difference: BEFOREAFTER

Thank you for that information Ken, it is much appreciated. I have the Elements version of Photoshop and have downloaded the extra Raw part of it. Busy getting ready for a holiday, it is darker there so I'm hoping to get some more good stuff with the Seestar.
Thanks again.
