North America and the Pelican (SHO)

Shot last night from Bortle 5 in Arkansas. I combined this with the 11x H-alpha frames I captured back in September, 2018. I originally borrowed that Canon 70-200 lens from a friend, but now I've bought my own and I love it. Its perfect. Here is the photos of my equipment setup.

Captured using Gain 200, Offset 40, Limit 75

Pixinisght processing:

Calibrated all subs with darks only

Stacked all channels with Linear Fit clipping

Linear fit OIII and SII to H-alpha

MLT noise reduction on each channel

Combined using SHO in Pixelmath

Histogram transformation

ACDNR noise reduction

Mophological transformation

Invert-> SCNR Green 100% ->Invert (recolorize the pink stars)

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.
