Description

301 60 secs unguided subs taken on the 21st of May from my home terrace with a Newton 250 F 3.9, a QHY183M on top of a Ioptron CEM60EC.

Aquisition, stacking, star elongation correction and deconvultion with Astroart. Image combination, cosmetics with PS.

ngc 5985, ngc5982 and ngc5981 are, from bottom to top, the galaxies in the image. This group is called "Draco Trio" because of their location in the Draco constellation. These are 3 very different galaxies, and ellictic one (ngc 5982), and edge on one (ngc5981) and a spiral almost face front one (ngc5981).

Thanks for looking
