The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy, NGC 253, is an intermediate spiral galaxy in the constellation Sculptor. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation. Distance 11.4 million light years.
The galaxy was discovered by Caroline Herschel in 1783 during one of her systematic comet searches.
GSO 10"F4 Newtonian, 1138 x 30 second subs or about 9.4 hours, Canon 1100D full spectrum, HEQ5 Pro unguided. Taken over 6 nights, stacked in DSS, processed in photoshop.
Lovely! Great colour, deep, lots of background galaxies, clean smooth background.
The centre of 253 is somewhat posterised (due to smoothing and sharpening perhaps), with some resultant loss of detail, but the galactic fountain streaks are nicely visible.

Very well done!
Thanks M&T! Yeah I see that. Happened very early on in the processing with a masked stretch. Fixed. I have to be careful not to be too aggressive with the mask stretches as they can leave some odd looking artifacts. Something I don't see too well when processing at 2am. Thanks for pointing that out.

I reckon it still keeps up with modern DSLR offerings. For the most part anyway.
Yeah I had a 6D for a while and it was more noticeable in daytime pics...astro it was more of a widefield wonder, but a mere incremental upgrade on the end of the scope, once I’d got over the wider FOV.
Thanks for pointing that out.
