I was a little underwhelmed by the results I got from my capture of this target with the RC6:

The Cat's Paw Nebula in SHO

That's probably because it is an F/9 scope, and I'm shooting from a Bortle 9 sky. Really not much to see on the paw's "basis". This is why I decided to try my hand at this target once again, this time using a much faster optic system, the Redcat 51, a F/4.9.

Although its focal lenght limits the final resolution, I'm more satisfied with this image due to the abundance of signal captured in every part of the nebula. This was also my first time trying RC Astro's BlurXterminator process, and I'm surprised by how much it improved the image overall texture.

I did capture RGB stars too, but decided not to apply them in the final image beacause honestly, at this resolution they just look like pixels.

Clear skies!

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.
Dismissals 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.
