Also known as Caldwell 70 is a spiral galaxy in the constellation Sculptor. It is one of the closest galaxies to the Local Group, and probably lies between the latter and the Sculptor Group. It is the brightest of the five main spirals in the direction of the Sculptor Group. It is inclined at an angle of 42° when viewed from Earth and shares many characteristics of the Triangulum Galaxy. It is 94,000 light-years in diameter, somewhat smaller than the Milky Way, and has an estimated mass of (2.9 ± 0.2) × 1010 M☉
3hrs24min in 4min subs captured 17/9/23
Equipment:
GSO 10" Truss RC, Losmandy G11 Mount guided PHD2 Orion Starshoot on 60mm guide scope
QHY 268c one shot colour camera, -15c, . Gain 57 Offset 30, NINA capture software, with Optolong L Pro filter
Najm Nazm Observatory Kelmscott WA,
Processing: Stacked DSS, processed Siril, PS2, PS6 (no flats etc) had really bad gradients had to work this one also bit soft I think focus shifted during the image run
