Pelican Nebula in HRGB

Pelican Nebula higher resolution in LHaRGB. This data was taken at the same time as the wide field DSLR data that formed the second panel of the North America and Pelican nebula mosiac taken on the SV80S.

This image used the ORION EON 115mm APO/ Williams Optics Flattener IV with the ASI1600MM-C and the EFW from ZWO.

This was taken with my older filter set before upgrading to Astrodon filters. The Filters were 36mm ZWO LRGB and 7mm Ha Nb.

The data was taken over four imaging sessions using gain of 76, offset of 40, USB of 60 and at -15C. The images were calibrated and stacked in PixInsight. This was my first successful image calibration all in PixInsight and used Dark Flats instead of Bias Frames.

The LUM and Ha were combined with pixel math.The Ha data had serious edge artifacts that are still visible and could not completely removed. The best results were with gradient exterminator in Photoshop. I also successfully used deconvolution on the combination LUM/Ha data that enhanced the resolution and reduced the star size.

This was the combination of:

LUM: 120 X 90s - 3 hours

Ha: 16 X 240s - 1 hour

RED 20 X 180s - 1 hour

GREEN 20 X 180s - 1 hour

BLUE 20 X 180s - 1 hour

for 7 hours total integration time.

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.
