M57 Ring Nebula!
The Ring Nebula is what's known as a planetary nebula, but the term is a misnomer from back before we knew much about these kinds of objects (they looked a bit like planets in early telescopes). Planetary nebulae are main-sequence stars, much like our own Sun, that are in their death throes, ejecting their outer layers of gas and becoming white dwarfs. This one is about 2300 lightyears away in the constellation Lyra, which also contains the bright star Vega. It's a little less than 3 lightyears across, which is quite large considering how small it looks!

This image is the result of two experiments I conduced: one was seeing whether my Celestron AVX could handle my 8-inch SCT with a 76mm Borg refractor riding atop as a guide scope, and the second was conducting super-short exposure astrophotography with my new ZWO camera (as a result of being pressed for time). Both were ultimately successful!

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.
