I really like the soft yet very detailed processing in the first version, beautiful image. I also find that the Ha stands out a bit too much in the new version.

Thank you!

Thanks everyone for your greetings!

Hello, for my first post here an image from last month, shot from my garden in the suburbs of Paris (Bortle 7/8) with my 200/800 newtonian (details below). The most interesting object is a pair of interacting spiral galaxies in Canes Venatici, NGC 5394/95 or Arp 84, also known as the Heron Galaxy, 107 millions l.y. from us. The field contains also the barred spiral NGC5378 on the right and, in between, the lenticular galaxy NGC5380. Here is the full-res image and a crop on the heron: Thanks for looking, Dan Technical details: 200/800 custom carbon imaging Newtonian with Romano Zen optics TS Wynne-Riccardi 2.5" coma corrector AZEQ6 mount ASI183mm+ZWO LRGB filters Guiding with ZWO OAG + ASI120mm +ASIAIR Luminance : 229*60sec, gain 111, -10°C Chrominance : 30*60sec each R and B channel, gain 111, -10°C, synthetic G Darks, flats, synthetic offset Preprocessing and stack with Siril, processing with PI and Rawtherapee Conditions : light pollution (Bortle 7/8), average seeing and transparency, first quarter moon.

Hello, I am Dan from Paris. I am already participating in French forums as well as in CN, but after reading many interesting discussions here for some time I'm happy to register on this friendly forum. I practice deep-sky AP from my Bortle 7/8 backyard in the suburbs of Paris with my 200mm f/4 Newtonian (some of my recent pictures here: https://www.flickr.com/photos/140784643@N06/albums/72177720298655177 ) I enjoy visual astronomy as well with my 250mm Dobsonian, mostly in summer under dark skies in the Alps (not worthwhile from home!).
