Cat's Eye Nebula (NGC 6543) mix of Lucky Imaging and Long Exposures

Acquisition type: Lucky imaging

I collected data on the Cat's Eye nebula region from May through July of 2023. The image is a HOO image for the outer nebulosity, LRGB lucky imaging core, and LRGB stars.

This was my first attempt at lucky imaging and spent many nights of trial and error. I initially tried to collect data using the NINA Lucky Imaging plugin but was having a difficult time centering the target, and the data was a large number of tiffs or jpg. After trying NINA a couple nights, I downloaded Sharpcap and Autostakkert! I had not used either program before and both were fairly user friendly. I also downloaded Siril but didn't spend enough time to learn it. I'm sure I could do better with more practice with the technique and programs.

For the LI core I shot 300ms exposures: 10,000 Luminance, and 5,000 each channel of RGB, and stacked 5% of the best subs. After creating tiffs in Autostakkert! for each channel, I used PixInsight to align the channels, combine them, sharpen, etc. The core image was then blended into the long exposure image in Photoshop.

There is a tiny red spot in the upper right side of the core that is likely some anomaly from my system. I was going to remove it because I assumed it was artificial but when looking at the masters, it exists in each channel (LRGB) from my lucky imaging session. So I figured I'd leave it in case it was real data.

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.
