M51: Hunting for the cloud
The whirlpool Galaxy M51 (NGC 5195/94) is a well observed object. You might think from an observer perspective there is not very much new, except you use the biggest / last generation telescopes. In this particular case, by surprise, it's different. reports in a preprint submitted by April 06th, 2018 "DISCOVERY OF A VAST IONIZED GAS CLOUD IN THE M51 SYSTEM" He and the Co-Authors perform very carefull ground base exposures using a 24 Inch Schmidt-Telesope located at Kit Peak with subsequent image processing and uncovers a cloud nobody has seen before.
Stimulated by this discovery, I started to work on M51 too. Up to know, I was not able visulize the new cloud, but I was able to perform the deepest M51 images, I ever have done with my 20 Inch Newton.

So, after having this small success, I'll continue working on famous M51.
