NGC 1300, UHC-S, 20 Nov 2015

This was a first-time observation of this nice barred spiral galaxy. I'm not sure why it isn't imaged more often; maybe because it is farther south (it transits only 30° above my horizon). About everything that could go wrong with this session did: I had problems getting my USB to consistently connect, there was really too much moonlight, causing noticeable gradients and high background noise, and my RA guiding performance was terrible, necessitating some image repair. The color came out with too much red, so I messed with it and am still not quite satisfied (I would like a bit more yellow, I think). All things considered though, I'm happy I got what I got.

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.
