AT115EDT + EAF + cem70 test: Messier 45 Pleiades

This is my first test of the fully set up AT115EDT: with addition of a Zwo EAF and mounted on the cem70 (instead of a cem26). I only had 3 hours of clear skies to test, so I chose 60 x 3 min on Pleiades with an L-pro filter.

Processing here is fairly minimal. Beyond the standard stack and light pollution removal:
* no star reduction
* no AI sharpening -- only 1% denoising and 0% sharpen, recover 50% detail
* very minor unsharp mask

I'm really pleased to see sharp stars to the four corners. In fact, the only issue are large (but dim and disperse) halos around the brightest stars (25 Tau and 27 Tau). I'll do another night without the L-pro to see if it's the 115 optics or the L-pro introducing them.

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.
