NGC7635: Bubble Nebula in H-alpha

This is a follow-on to the testing of my recently acquired ZWO ASI6200MM Pro on a C11" EdgeHD @ f/7 with a Chroma 5nm Ha filter. My intent is to generate a nice Hubble Palette of this beautiful DSO but given I have to wait for the next new moon to capture O3 and S2 data, I'm posting an initial 5-hr Ha image. Depending on how the O3 and S2 data turn out, I'll see if I need to add more or redo some of the Ha data but I like this initial version. I had to crop a little due to some image shift during the night but for the most part I thought it came out OK under my sky conditions over 2 nights. Seeing was OK but the humidity continues to be high between 88-94%.

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.
