Sh2-119 (Clamshell Nebula)

Used a one-shot color camera (ASI294MC) with Optolong L-Ultimate filter on this Sharpless target #119, more appropriately named the Clam Shell nebula. The ASI294 woefully under samples the image when paired with the RedCat51 scope, but what the heck ... I'm still learning how to do this stuff! ;-) Nothing fancy with processing - pretty much straight out of PixInsights WBPP, with SpectoPhotometricColorCalibration and EZ SoftStretch. I am just learning the ropes on how to use GeneralizedHyperbolic Stretch and render OSC data using separated Ha and Oiii wavelengths - would like to try this on this data. I really like how others have rendered this target.

Your tips and comments are welcome!

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.
