Cygnus Loop

Revision title: HOO Version

This was my first attempt at a mosaic, and was shot over six nights in June and July of 2022 in Colorado and Nebraska. It is two panels which were manually aligned, with the full resolution image at approximately 81mp (and too large to upload here).

The original version from 2022 was processed using SHO data in the Hubble palette, though I have since uploaded a 'final' version in the HOO palette using PixInsight.

Title: HOO Version

Description: This is an updated version from after I had migrated to PixInsight. I also decided to discard the SII data and process in the traditional HOO palette instead. I believe there was too much overlap between the SII and Ha data given that I had been using lower-end 7nm filters at the time and this was making it difficult to cleanly separate the channels.

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.
