M42/M43 - running away with narrowband

Revision title: Pulling out the detail with Startools

A similar set up to my last image, less the SCT reducer, this image is narrow band Ha and OIII using my Optolong L-eNhance filter. Longer integration time is needed using this filter. To be honest I'm not sure that there is much more detail visible, but I was surprised to see a little emission in the running man a predominantly reflection nebula.

Title: Using SIRIL v1.06 to pre-and post-process

Description: I love the colour and extra background I've been able to pull out with my rudimentary knowledge of SIRIL. Dark frames do not seem to have worked properly, perhaps because I processed all exposures together - although it appeared to put these in layers. I'm sure it is possible in SIRIL, but using a similar approach, Startools has done a much better job of taming the highlights and extracting detail from the core. Comments / thoughts welcome.

Title: Pulling out the detail with Startools

Description: I have taken my SIRIL image and used HDR in Startools to pull out detail in the core, with a little sharpening. Photometric colour calibration in SIRIL has allowed me to reveal real star colour for the first time, when using an L-eNhance filter - nice.

Title: Alternative colour scheme

Description: Processed in Siril using basic background neutralisation and colour calibration, Astrosharp, Starnet removal and recomposition using 'RGB' stars. I like the vibrant blues.

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.
