M42 in narrowband with my trusty C8

Imaged M42, the magnificent Orion nebula, in narrowband on the nights of February xx/March 21, 2022. HDR composite of subs at 1 second exposure to capture the Trapezium stars and 120 second exposures for the nebula.

Imaged with Celestron 8" SCT at F6.3 (1290 mm focal length) using a Celestron focal reducer/field flattener, Optolong L'enhance dual band Ha/OIII filter, and full spectrum modified Nikon D5300. Total integration time of ~1 hour (31 subs at ISO400 x 120 sec, 19 subs at ISO400 x 1s).

Pre/post-processing in PixInsight. Images calibrated using Weighted Batch Pre-Processing (BPP) script using darks, flats, and flat darks. Separated R/G/B channels using Batch Channel extraction script. Registered and stacked individual channels using StarAlighment and Integration processes. Initial post-processing steps included: cropping and gradient removal with ABE. Generated HDR image using HDR composition process. Additional post-processing included: noise reduction using MLT, stretch using Generalzied Hyperbolic Stretch, HDR transformation using EZHDR (blend =0.4, layers=6), using pixelmath to average the EZHDR blended image and HDR image to further balance the contrast, and lastly using pixelmath toand additional denoise using TGVDN process.

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.
