M78

This target has been the quintessential pebble in my shoe. I have tried several times to image this difficult gem, each time falling woefully short of my vision. Noise has always been an issue, as well as LP, for M78 never rises above about 40 degrees for me, and 2/3 of the time it is visible it is awash in a nearby light dome. This attempt I feel is the most respectable. It contains data from two scopes (FSQ 106 and TOA 130), mostly the FSQ, with high detail areas being supplemented with TOA data (about 7 hours). I do have the linear stacks, so there is the option of adding to this data--maybe with the C11Edge? Or maybe keep adding to the wider field until all noise is suppressed entirely. I love M78--it is up near the top of my DSO list, so I know I will keep shooting it.

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.
