M_57 - Ring Nebula - 2021_08_05_2300

Name of Object: M_57 - Ring Nebula
Image Type: RGB
Exposure: 60*30sec - Only 23 Best Stacked
Date: 08/05/2021
Bortle: Class 4

Gear:
Telescope: Orion 150mm/750mm Newtonian (Started life as a Starblast 6)
Mount: Orion Skyview Pro with Goto Upgrade
Tracking: ZWO ASI120MM-mini + Orion 50mm
Main Camera: ZWO ASI183MC (Uncooled) + 2x Barlow

Software & procedure:
Kstars/Ekos + Indi on Laptop for mount control, guidance, and image acquisition.
Siril for stacking, color correction, and histogram editing.

Notes:
With 2x Barlow I'm at 1726mm of focal length.
Humidity was awful, and the seeing was below average. Many exposures ruined by tracking errors and dew. I'll need to lower my individual exposure time for the next acquisition if I use this much focal length.

Description: Reprocessed images. Specifically did not debayer anything until after preprocessing with darks and flats. Background seems better, but colors are still muted. I think the muted colors are mostly due to atmospheric conditions and low integration time. I also noticed that I wasn't dithering between exposures.

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.
