Sh2-101 and Cygnus X-1

Black Holes are objects that have captivated me since I was a kid. Their mysterious yet terrifying nature just sucked me in (no pun intended). Since getting my first photography rig last year I have wanted to image the area of the tulip and point out the binary system of X-1, but when one of my friends directed me to this site and I saw that others have imaged the shockwave directly with gear similar to mine I knew I had to give it a shot. Last year was a flop, but nine plus months of refining my processing and a few upgrades later, April rolled by and I started this multi day project. I was worried my OSC investments might have not been enough, and with intermittent weather I was getting discouraged another year might pass me by like the winter sky. Luckily I got a break and had a good hand full of days to give it my full attention, and I am glad I did. I was able to pull some of the blue out of the shock structure without harming the rest of the data too much. As with everything in the hobby, it can always be better. Its still early in the season so I may try to double my time on it at a later day, maybe travel to B1 skies!

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.
