Sculptor Galaxy (NGC 253)

Capturing this galaxy from Julian, CA is a challenge. It's only between 15° and 31° for about 6 hours of dark sky during mid October.

Here I used the best 5-minute subs I could capture during this dark cycle. Unfortunately the weather wasn't great and the skies not as steady as I'd like. This example uses 24 x 5 min L between 2.4" and 3.1". RGB subs averaged around 3".

I hope to gather more L subs this week. We'll see how it goes. (-:

Processing is very simple...

Luminance: BlurX, PI Stretch, HDR, DBE, Noise X. USM 200 1 0 applied after I gathered more L.

RGB: DBE, SCC, BlurX, BN, Stretch, NoiseX, Color Stretch

"The Sculptor Galaxy (also known as the Silver Coin, Silver Dollar Galaxy, NGC 253, or Caldwell 65) 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."

Description: Captured additional L. Total 48 x 5 min between 2.4" and 2.9". Extra L permitted masked application of USM 200 1 0.

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.
