NGC 253 – Sculptor Galaxy – LHaRGB v1

Has been quite a while since I last imaged this large, beautiful spiral galaxy in the southern constellation of Sculptor, NGC 253 known as the Silver Dollar Galaxy, Silber Coin Galaxy, or just Sculptor Galaxy.

A lot of H-alpha data has been used, thus the rendition is different from the DSLR attempts back in 2016.
