This is one of those targets where I questioned aiming directly at Regulus to image the elliptical galaxy Leo 1. Not deterred by previous efforts to image things sitting right next to bright stars we put the TOA-130 optics to test here. And I think this is probably at the limits as you start to see a breakdown in the natural falloff of the bright stars glow. Maybe the extra glass introduced in the flattener contributes some to the ring type effect seen around Regulus. Additionally there's a flare from the glass that streaks across the entire frame. But it still managed to get some extremely fine detail out of Leo 1. There's even an interesting Ring galaxy if you follow the flare line down to the left.

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.
