M100 and friends


Recommended Posts

I decided to reprocess my M100 data from last year.  This time, I decided to present the image in a much wider field of view, which has the benefit of highlighting the various background galaxies. The other notable changes are that the blue spiral arms are emphasized more and the overall brightness of the central galaxy has been increased.  At just over 12 hours integration time, this was taken with my Esprit 150.

First class image Alan - very nicely done and a worthwhile improvement on the original in my view.

Thanks - I don't often reprocess but I'm pleased that this time.

      A reprocess of my M100 image which is also in this album.

      M100 is located in the Virgo cluster at a distance of 55million light years, it is one of the brightest and closest galaxies within the cluster. It's a spiral galaxy with a pronounced bar at its centre.  Quite a few supernovas have been found here, the most recent being in 2019, designated SN 2019ehk which was discovered on 29th April.  The LRGB image represents 12.3 hours integration time and was taken with my Esprit 150.

      (For those that might be interested: the data was gathered between Feb and May 19 , so I was wondering why I couldn't see the supernova in the image. On examination of the individual subframes it transpired that I captured it in  only a handful of subframes, it's first appearance was on the night of 29th April.  So, when I stacked the image,  the supernova was simply rejected as a statistical error..... I think I've come to the conclusion that I'm not cut out for supernova hunting ).
