IC 5070 Pelican and Vicinity – A 3-Scope Synthesis

Scopes used:

AP175 (DSW) HSO

RCOS 14.5 (DSW) HSO

DreamScope 16 (ATOE) LHRGB

Total exposure: 52.7 hours

Image width: almost 1 degree

Tools: PixInsight, Topaz, Skylum, ACDSee, SWT

Obviously, the different scopes had quite different image sizes, so they were nested in this image, converging upon the region of the Pelican nebula. The most expansive images, from the DreamScope, formed the base for the nesting, and the RCOS had the greatest resolution and narrowest image.

The narrowband images were mapped into the corresponding RGB images, with an estimated amount of hydrogen beta also added to the blue image. The composite image received a photometric color calibration. Stars were removed before additional minor color adjustments of the nebula, sharpening the L image and preliminary noise reduction. After introducing the adjusted L into the adjusted HSORGB and replacing the stars, a final noise reduction and downsampling yielded this image.

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.
