M57 - Two Newtonians for high resolution and the outer Ha shells

Acquisition type: Lucky imaging

Hello everyone,

a new cooperation with @Guillaume Gruntz (Thank you) on the ring nebula. As usual, we imaged with our 2 newtonians using lucky imaging and long exposures to mix our data. Guillaume with his T250 f/4 and me with my T350 f/4.7.

We really love this nebula and here the goal was to bring out maximum detail in the center while showing the extremely faint Ha shells.

Mixing such different data with 3 cameras, 2 telescopes with different samplings and resolutions requires good processing practice to make it look good.

I hope you will appreciate this work which took a month and a half, especially to Guillaume for the long exposures. There are 45 hours sorted from 75 hours of data and 10 hours of processing.

The final version is a crop, the 8K full frame is here :

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.
