Cat's Eye Galaxy, M94

A few nights ago I decided on M94 as my target for the night, as I've had it on my list for a while and it has already moved into a pretty unfavourable position, so it will be unavailable to image for the next several months.

Little did I know what I was setting myself up for with picking this target. After processing that night's subframes the way I usually do other galaxies, the results were... well, less than spectacular, to put it lightly. It was only at that point that I realised the combination of a very bright core and a very faint outer ring will make this a very challenging one to process.

So I went back to image it on the next two nights as well to get more data, particularly for the outer ring. As this was my first time imaging the same target over multiple nights, I had to learn how to combine multi-night imaging sessions. As well as how to process high dynamic range objects without blowing them out or losing too much faint detail. I'm not completely happy with the final result, but it's still a massive improvement over what I was able to put together on my first attempt. Just feels like this galaxy needs and deserves a lot more integration time, so I'll be sure to come back to it again.

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.
