SH2-235 in HSO

This was a pretty difficult target from light polluted skies. I integrated 906 two minute subs taken over 5 different sessions in a two week period. At 18 hours it felt like there was a lot of grain still in the larger nebulous areas, so I continued to image. OIII with 307 frames barely looked like a smudge on the brighter small nebula at the center of the image. So I processed this as HSO, which looks really pleasing and let me show off the HA signal much better than SHO could have. The star colors are as close to natural as I can get without shooting RGB data.

Description: Just for grins, the SHO version. You can see the planetary nebula a bit better in this one.

Description: I still think HSO is the nicest version of this target. I reprocessed again using NoiseX, StarX, and BlurX.

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.
