Description

Shot from my front yard, in Nova Odessa (São Paulo, Brazil) suburban area.

No motorized mount or equatorial mount was used, just my good old tripod, Stellarium and some trial and error for locating it.

Stacked from 20x3.2" light frames + 5x3.2" dark frames, at ISO12800 on my Sony a6300.

Lens used was a Jupiter 21M (200mm), at f/4 and a Viltrox Speedbooster, acting as focal reducer (~0.71X), bringing the lens to around 140mm f/2.8, which allowed most of the brightness in the picture in first place.

Special thanks to my dad and my dog for the great company and for the awesome night hunting for the comet.
