IC 5070, Pelican Nebula, 23 Jul 2012 (David Dearden)

IC 5070, Pelican Nebula, 23 Jul 2012

A difficult find a few nights ago, much easier once I looked for the two bright stars (56 and 57 Cygni) and patterns around them. Lots of clouds and wind made this a hard image to acquire.

Date: 23 Jul 2012

Subject: IC 5070, Pelican Nebula

Scope: Orion ST80 + 0.5x Antares telereducer

Filter: Baader Fringe Killer

Mount: CG-5 (Synta motors)

Guiding: AT8IN + 0.5x Antares telereducer + DSI Ic + PHD

Camera: DSI IIc

Acquisition: Nebulosity 3.0.8

Exposure: 16x300 s

Stacking: Neb 3, bias included, normalize first, trans+rot align, 1.5 SD stack

Processing: N3 crop, color balance, digital development with 1 level of sharpening, a little Keller curve, a little power stretch, saturation boost. CS5 curves & levels. In one layer use Astronomy Tools color blotch, deep space, & space noise reduction. In another, unsharp mask. Gaussian blur layer mask (hide all) the unsmoothed layer on top of the smoothed one. Flatten, star color enhance, and saturation boost.

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.
