Capture NGC 300 Southern Pinwheel Galaxy over 2 nights here on the South Coast NSW under clear skies and good conditions
Only the second time I’ve captured this magnitude 9 dim galaxy located in Sculptor
Not to be confused with M83 which has the same name description.I’ve read that it is also called the “Spiral galaxy in Sculptor”. Any other references to its name ?

Thanks Mike
Unlike many other spiral galaxies NGC 300 gives a “smudgy” appearance with a soft core and wide spiral arms
It’s not an easy target to capture and process especially when you only have 1000mm of focal length
Pretty happy with the end result and the rigs performance ( can’t expect any more out of it )
Cheers

Great image of the Galaxy against a very nicely framed and detailed background. A first class colour image.

Tay,
Thanks for your generous comments
I spent quite a few hours processing this one and was quite pleased with the end result, quality data helps too.
You obviously noticed the dozens of little faint galaxies spread around the field , I’m surprised my scope picked up so many, another feather in the cap for the 2600MC. Great camera !
Cheers
Martin
