Messier 100
Here's Messier 100, a grand design spiral galaxy in Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, it has a diameter of 107,000 light years.
89 x 120 second exposures captured 16/04/21 with my ASI294MC camera and 9.25 SCT telescope.
My first 3 hour exposure image and had to do my first meridian flip as the object moved past due south during the exposures!
Hope you like it.
Regards
Graeme

Re: Messier 100
Thanks Hans.
It was the first time in ages that there was a clear night with still air, no Moon and no work the next day!

Re: Messier 100
Is there a higher resolution image that you can share? This JPG is incredible but leaves me wanting more!

Re: Messier 100
Thanks for the kind words all.
Here's a couple of 45Mb png files. I reprocessed the first one in an attempt to bring out the colour of the spiral arms.

Re: Messier 100
Amazing! And the depth you've captured with maybe a dozen or more objects also visible in the view makes me wish I still lived in West Texas so I could use my small telescope again. Florida skies just don't get dark enough, even down in the swamps of the Everglades.Graeme wrote: ↑19 Apr 2021, 18:01Thanks for the kind words all.

Re: Messier 100
Cheers PJ
The full resolution images are full of surprises. Sending them to nova.astrometry.net gets an annotated version returned. M100 has a number of satellite galaxies.
There's a lot of galaxies to be found in the direction of Leo and Virgo!

In the best tradition of Scuttlebutt
In other space related news, this article has a great picture of the location of a man-made distant object:

It reminds me of Pooh's map showing where the Woozle wasn't

Also, the linked article on the use of New Horizons to get enhanced parallax imaging is fascinating, too!

Re: Messier 100
15 years to catch up with the Voyagers and still only 50 AUs! It's a long way to Alpha Centauri!
You should see the images that the famous French astronomer Crasseux produced!

Re: Messier 100
You mean the one that's not on this list of notable French astronomers?

and doesn't seem to turn up in various Google searches?
