NGC4656 20170527
Here an image of another peculiar galaxy, also known as the Crowbar or Hockey Stick Galaxy. It lies within the vicinity of NGC4631. The distortion of NGC4656 as well as that of NGC4631 suggests that both galaxies interacted in the past. Note the very faint extension of stars to the top-right. North is on the right.
Technical data: Imaged from the 27-28/05/2017; 50 x 5 min. exposures through a GSO RC 8" f/8 with a PrimaLuceLab 700Da cooled at -10 degree Celsius; ISO 3200; no light pollution filter; Stacked with DeepSkyStacker in autoadaptive weight averaging mode and further processed in Fitswork4, PS and Noiseware Community.
