NGC 7635 - blowing bubbles

Lying approximately 7000 LY away this 7 LY bubble is extraordinary, fuelled by stellar winds travelling at 4 million mph, from a 4 million year old star in a region dense with HII emissions [Ref Hubblesite].

I collected just over 2 hours data, and my image comprises Just 90m data taken through my Optolong L-eNhance triband filter. 120s exposures are short and the 35nm bandwidth in OIII tends to a noisy image. The best 60% subs were aligned and stacked in ASTAP then processed using Startools. I look forward to adding some RGB data in due course, and using a dedicated Ha filter.

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.
