Markarian's Chain

This was my fourth time using my new setup, each time I have gone out, I have attempted to do something new that night. After my previous session's failure with focus, I was using this night to test out my new ZWO EAF. With the 70% illuminated Moon I didn't expect particularly good images, but I was surprised at what I could reveal with only 70 minutes on this relatively slow scope.

I drew a bad hand this night in regards to satellites, I had to throw out about 30 minutes worth of exposures, including quite a few near the zenith. But I consider this image a total success as the EAF performed flawlessly. I look forward to future sessions with this now completed set up, with the EAF to ensure pinpoint focus, I think I'm now confident to let this thing run by itself for a long while.

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.
