Hello!
A capture from last night: NGC4631 (Whale Galaxy). The nearby companion is a dwarf elliptic galaxy (NGC4627). Into the frame I have also (unplanned) NGC4656 (Crowbar or Hockey Stick galaxy). Although I was intended to capture only luminance (and to let the RGB for tonight), I shortened exposure time to 2 hours for L and I took also the RGB frames, 20x2 minutes each, just to be sure I can finish the image. So, total exposure- four hours. And tonight I'll pick another target.
Setup: newt SW 150/750; ASI1600MMPro.
Clear skies!
Great image Marius with really nice colors and details!

Wonderful Marius, you captured some interesting detail in NGC 4631, plus is little "pup" NGC 4627. The pair are also known as ARP 281.
The interloper in your image, NGC 4656, is indeed a really curious and delightful object itself. Its distorted appearance is thought to be due to an interaction between it and the ARP 281 duo. Well done!

That's a great image!
How heavily did you crop that?

Thank you all. @Larry 1969 The first image was a little cropped on the edges, it has 4509x3402 px( at least when I uploaded it), the second has 1886x1291 px , so about 40% from the first. The resolution of my setup (ASI1600 with 750FL) is 1.05arcsec/px, that's what matters. The first image was resized by this site, I don't know why ( its size is only 0.8MB).

Thanks! My resolution is .92as/pixel so I might give that target a go!

that is fantastic. Great structure in the Galaxy and the "starburst" region showing really well.
