It took 3 nights to collect enough subs for the Hamburger. I was only able to acquire partial runs each night due to the rude Texas weather. Wind storms and tornadoes were lurking around this week. Tuesday night I was watching the run with auto-guiding showing an excellent (for me) 0.19 RMS on the Dec and 0.249 RMS on the RA axis when wham.... the roof of the remote observatory closed due to sudden winds of about 45 mph. It wasn't predicted to do that. So much for Tuesday. I managed to cobble together about 29 subs @ 10 mins over 3 nights this week with the 155. I threw away about that many due to erratic weather.

I think the Hamburger is served!

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.
