Reflections in the Mist

I re-shot one of my favorite regions in the sky last January when I was trying to get used to my new CEM40, spanning M45 through the Taurus molecular cloud, but didn't get enough integration time to pull out the level of detail I wanted. Fast forward 6 months, and now that I'm starting to get a better feel for PixInsight and the marvelous work of NoiseXTerminator, I thought I'd go back and try to reprocess it.

This is a three-panel mosaic I shot with my mono-modded Canon 60D and luminance filter, Rokinon 135mm f/2 lens at f/2.4, riding my CEM40. I shot color data with my 600D, my older Rokinon 135mm lens that has bad corner stars, and my iExos-100. I got about 2.5 hours with each camera on the middle and right panels the first night, and about 5 on the left-most panel the second night. Both cameras were collecting 120-second subs at ISO800. Calibrated and stacked in APP with 30 each flats, dark flats, and darks for each camera, then light pollution gradients removed and mosaicked and recomposed in APP as LRGB. I'm sure this can be done in PI, but I don't know how to do that yet.

My initial results in APP were noisy so I pretty much put the data on the back burner and chalked it up to a learning experience with the CEM40. But recently bringing the data into PI and running it through NoiseXTerminator, followed by Starnetv2 provided a surprisingly good result considering the short integration time and the banding I see with the mono Canon.

Hope you like it! C&C welcome and appreciated.

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.
