M 94 - The Croc Eye Galaxy

M94 - The Crocodile's Eye or Cat's Eye Galaxy (looks more like the crocodile's to me 😄)

The weather did not allow me to take Luminance for this object so I instead built a synthetic luminance. The halo that surrounds M94 can be seen to some extent, but to reveal that faint structure in more detail, I need Luminance and darker skies (I don't have one or the other 😢)

Synthetic Luminance is a technique that I have used quite successfully lately. Every time I start a broadband object I take the RGB frames first. This way if the weather betrays me, I can at least build a synthetic luminance, process the image and get a fairly reasonable result.

Location: My backyard in Caguas, Puerto Rico / Sky Quality 18.3 (almost Bortle 8, yes it is BAD!)

Description: Created a new range mask using the GAME script to combine different processing approaches and get a bit more of the faint halo that surrounds M94

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.
