NGC 300 The Southern Pinwheel in (L)RGB Reprocessed and Cropped

NGC 300 (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 one of the brightest of the five main spirals in the direction of the Sculptor Group, including NGc55 (The String of Pearls) and NGC 253,The Sculptor Galaxy, and NGC 247, The Needles Eye Galaxy. It has an Apparent magnitude of 8.13 and Apparent size 21′.9 × 15′.5 and it is about 94,000 light years away. After the wettest October in recorded history in Australia, I am lucky to be 247 meters above the Nepean Valley. Some areas are coping their 4th flood in two years and it is not over yet. So a new moon, with a clear sky, good seeing and no major light problems from neighbours, was pure gold and delivered 32 usable sub-frames with no rejects, despite a bit of cloud earlier that danced around my field of view but didn't affect anything.

My only problem was horrific gradients from the high-beam headlights of passing cars on the road outside my house hitting the tops of trees next to tiny observatory. I yearn for a real dark sky and clean data that doesn't need mauling by DBE and ABE to clean it up and then knowing when you have gone too far in Pixinsight.

So here is more restrained cropped and less lurid version I like a lot more with a more even and less blotchy background when viewed through a properly calibrated monitor.

There are so many galaxy clusters buried in the background of this field it would be nice to not be sky limited and go 10 minutes or more, instead of the 300 second compromise. But that's a quibble. I should probably buy a lottery ticket now.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
