L-eNhanced Orion

Trying something a bit different. I figured the OIII passband in the L-Enhance filter would be sufficiently wide to let in enough light to still show the reflection part of the nebula, while also getting some detail in the surrounding h-alpha clouds. I think it turned out pretty nice, though the colors are a lot wackier than I expected.

Stacking a whole bunch of short exposures seemed to have worked here. I couldn't expose for much longer or I'd blow out the center of the nebula, even with the narrow(ish) passband of the filter.

The original, untweaked image was the greenest DSO image I have ever seen. Not sure why.

There's also some odd vertical banding in the image. I'm not sure if it's walking noise, which I have never seen in images using this camera before. It might have something to do with the scope being accidentally rotated in the mount during the meridian flip.

Description: Restacked with new bias and flats that now match the color balance/offset settings for the light frames. Colors looks slightly more plausible, but otherwise there doesn't seem to be a huge difference.

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.
