Messier 57 A Planetary Nebula in Lyra

This is a re-upload after the database restore. Used a Denkmeier SCT Star Sweeper to reduce focal length and and f-ratio to approx. 1600mm or f6 respectively. Aquired this piece of equip second hand und most obviously it was crafted for the non-ACF version of the LX200 since it introduced vignetting and stretched stars in the very cornes. But the faint galaxy IC 1296 got obious since I was not shooting at f10 as usual. Full moon plus 20hrs made the background grainy and some mottle is still remaining. The night after I was aiming again at Messier 57 this time without the Denkmeier and at full focal lengt of 2540mm. To be uploaded soon...

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.
