Return To The Cat's Eye

Here it is, the next stop on the Ritchey–Chrétien revenge tour. We have a pretty basic Cat's Eye here. I wanted a wider FoV that showcased the surrounding galaxies and little galaxy clusters, alas I needed dark skies for that LRGB component. As the forest fire smoke sets and and astro dark wanes, I will have to settle for a simple Ha and Oiii combination.

For this image, I traded out the Apex-L reducer for the generic 0.8x reducer to get more focal length.

I have to say that the core came out nicely. You can compare and contrast with my first go at the Cat's Eye here: https://www.astrobin.com/71qdvr/

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.
