Sagitta, Vulpecula

A wide field centered on Sagitta (focal length 37.1 mm, aperture f:4.9). M27, M71 and the Coathanger are included; also Barnard's E.

The original version was a quick-and-dirty job preprocessed with DeepSkyStacker (on Wine on Linux) with darks but no cosmetic correction, flats or bias, and postprocessed in Siril 0.9.12 with final curve tweaking in GIMP 2.10.

Revision BB, made entirely with SiriLic and Siril 0.99.7, has cosmetic correction and better color and is livelier; even too lively. Revision BC has got flats at last, and again curves adjustment in GIMP.

BB

Description: Preprocessed in Siril 0.99 via SiriLic with no bias or flats, 40 darks with dark optimization, cosmetic correction (sigma 3, 3). Stacking: mean with rejection (winsorized sigma 3, 3). Postprocess in Siril too: subtractive background extraction, green noise removal, photometric color calibration, color saturation increase, Asinh transformation, histogram stretching.

BC

Description: New process: 25 lights, 40 darks, 40 flats. Stacking: mean with rejection (linear fit). Postprocess much as in revision BB (background extraction, photometric color calibration, green noise removal, color saturation enhancement, Asinh transformation, histogram stretching), plus curves adjustment in GIMP.

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.
