Absolutely love this bright target in the Winter sky, The Rosette is amazing. close or wide; super wide or super close.

This data was acquired about 6 months ago but I was not feeling confident in my processing skills. I would welcome critique. I am feeling more accomplished. Thank you for looking.

~~~~Tekkie stuffs:

Telescope: Explorer scientific Ed 80 FCD-100

Camera: ASI1600pro

Filters: Astrodon E series SHO

Mount: Atlas EQ-G

Guiding camera: 290 mini OAG

SHO: 14:46:50 at 2 min with extra 35 min of Ha at 5min subs.

Total integration time: 4.25 hours

Seeing/ environment: 1.8- 2 arc second

Bortle Class: Class 5/6 Backyard~ Central Indiana

Dates of acquisition: 12/8 and 20/2019: 1/14, 1/22/2020,

processing Pixinsight:

processing: considerations. MULTIPLE nights with good alignment (2 degree error allowed in SGP) flat and dark calibration on 12/22/19 off but salvaged and rotational errors requiring the crop you see

synth lum pulled

Aligned all to each other.

Crop

DBE to individual frames then PIX combine with the following formula to allow HA in all 3 channels 10-15 percent

RGB combine the HDR RGB masters

RGB workflow~BGN~ MLT for Noise reduction

Lum workflow~decon with autopsf 40 iterations 5 layers; MLT for noise reduction

HT for both with Bg at 10%;

TGDVN and a restretch to bring up the black point

MANY MANY Curves with color masking script masking for lightness and sat boost

XPTR with Lum mask for lum boost; LHE for sharpening.

Morph to reduce the stars just a bit and ICC to end.

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.
