Witch Head Nebula

This is my final image from the Winter Star Party. The processing gave me fits over and over again and ultimately it came down to the data wasn't quite what I hoped for on this one. I could commit to a lot more time on the project, but I will be taking it again next year and starting over. I also decided that I wanted to fix the weird diffraction effect from the WO Star71 and it seems to have worked in testing and I want to get less undersampled. I'm debating between upgrading my QHY8 to a QHY10 for the smaller pixels and bigger full well capacity or putting the QHY8 on the SV105 and bringing the QSI to the WO Star. Ahhh, decisions decisions. Anyways, I'm done with this for the moment, but as always love any feedback and thanks for looking! I can't wait for the WSP next year, it was quite a productive trip. I will have to make a montage of all the images I gathered in that week.

VB for the orientationally challenged

VC fixed some artifacts.

VD worked on a little more accurate color sampling

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.
