This is going to be my last image for a while. In addition to not being able to do astrophotography due to work obligations, I also broke a push screw on my Ritchey-Chretien and can't get it out, so that scope is out of commission for the foreseeable future (there's literally no way to collimate it). I got a Moonlite for my Newt, but I have no idea when I'll be able to attach it, so unless I just want to put up with the focuser tilt that's been annoying me for ages, that scope is also out of commission until I can find the time to drill. I still haven't got replacement parts for my AZ-EQ5 and I have issues balancing smaller scopes on the EQ6-R, so the Sharpstar and ES80 are out of commission as well. I miss this hobby like crazy.

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.
