This with two rigs and two ZWO ASI533mm Pro. The AP 130 EDF was imaged longer at 480s subs to match the exposure of the faster FLT 156 with Apex-ED L Reducer with the exposure of 300s. F/6.5 is the AP 130 EDF focal ratio with the new field flattener while F/5.24 with the FLT 156 with the Apex ED-L reducer. Stars on the FLT system did not look good so the stars were lifted on the AP 130 EDF system in place. I since put the William Optics Flat 7A on the FLT 156 for a focal length of 1000mm.

Also have an OSH version in the revision session.

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.
