Orion Nebula (M42)

Hi folks, I finally had some clear skies! I was super excited to see that I could preserve the details of the trapezium cluster in the core of Orion with short exposures and by using a High Dynamic Range (HDR) transformation technique in Pixinsight. As you undoubtedly know, the trapezium stars are responsible for much of the illumination of the surrounding nebula.The picture is a so-called HARGB integration where I used the data from the Ha narrowband filter to accentuate the hydrogen-rich clouds of the nebula. Exposure time was kept at 30 seconds at a low gain level in an attempt to preserve the details of the core and avoid ‘overexposure’. I photographed the nebula on January 28, during a cold and relatively cloudy night from my backyard in my hometown Utrecht, The Netherlands (bortle class 8 skies).Information about my astrophotography gear and this picture are as follows: Gear used:Telescope: Celestron Edge HD 8”
Camera: ASI1600MM Pro
Filters: Ha 7nm narrowband + RGB broadband
Mount: SW EQ6-R ProInfo about the picture:Total Exposure time: 50 minutes (only)

Blue filter: 20 subs x 30 seconds
Green filter: 30 subs x 30s
Red filter: 29 subs x 30s
Ha filter: 22 subs x 30s Integrated and processed in Pixinsight (HDRtransformation is a godsend). Best regards, Wido - AstroForum

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.
