NGC 253 Silver Dollar Galaxy Over Ten Years

I have done this three times in the past 10 years and it was one of the first galaxies I tried to photograph. The fact that I could see it at all in 2011 gave me hope at the time. Anyway, I think there was an improvement in imaging over time from the C8, to the AT RC10 to the Stellarvue. Just shows anybody can learn this hobby.

Parenthetically, I believe that the one taken with Rob's scope in 2017 may be the best in terms of image (I recall the FL was 1400) but I was able to get better color with the Stellarvue probably due to better processing and photometric calibration etc. I did not add H-alpha to the latest version. I may collect some and see what happens.

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.
