Cat's Eye Nebula (James R Potts)

Cat's Eye Nebula

Revision title: Reprocessed image

I started capturing this object back in April and May. I saw someone list this as a good beginner target. Maybe I tried to do to much, but this was anything but a beginner target for me. I have played with the processing on and off for the past 2 months and finally have something I think is worthy of posting, but I am still not all that happy with it, considering all the data I gathered. Some of this was captured from my drive way (bortle 5 skies) with a NB filter and some was captured at a dark site (bortle 2) with just a IR/Cut filter. The difficulty I have had with this is two fold. First capturing the outer nebulosity without blowing out the core and getting more detail without have an extremely noisy background. I didn't not do a good job with either of these. I ended up processing the main image and did a little processing on just the core and added it in the corner of the image.

If anyone has some tips on either the best way to capture or process this image, I am all ears. Thanks, Jim...

Title: Reprocessed image

Description: Funny sometimes you go back and look at images you took, that at the time you thought were good. But when you look at the image you see all this noise and ugly background. Well this is one of those, so since I feel I learned a lot about processing since I first took this image, and the skies are not cooperating, I decided to restack and reprocess. I definitely improved the background, reduced the noise, which I think help the nebula pop out more. I was still unable to get the detail on the nebula without blowing out the core. So I just processed them separately and like last time placed a small blown up image of the core in the corner. Jim

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.
