Lunar progression (Victor Van Puyenbroeck)

Lunar progression

The revisions of this image are meant to show my progression in lunar photography.

Revision D was shot on May 5, 2017:

The luminance data was shot with a 3X barlow (1600 mm effective FL) through a red filter. It's a 22-panel mosaic, 30 second video per panel, stacked in AS!2 and merged into a single frame with Hugin. Deconvolution and post-processing in PixInsight. I shot the color data at 480 mm FL (fits just on the ASI120MM chip) and combined this with the high-resolution R data in PixInsight.

Revision B/C were taken on Mar. `16, 2017:

This is a 2-panel R-RGB mosaic, shot with my TS 80mm APO and new ZWO ASI120MM camera with (L)RGB filters. It's also post-processed mostly in PixInsight.

The 25% best frames from each 60-second video were aligned and stacked in AS!2. These 6 images were then opened in PixInsight and each channel was merged to a full lunar disk with GradientMergeMosaic. I then combined the RGB channels and applied color calibration, SCNR and saturation adjustments. The original red channel was also used as a luminance layer and sharpend with the Restoration filter and MMT before LRGB combination with the RGB image. Final adjustments were made with LocalHistogramEqualization and UnsharpMask.

Revision A is my first lunar image with a telescope.

It was taken on Feb. 15, 2016 with my Orion ST80 telescope, mounted on Alt-Az photography tripod. Single frame shot at ISO-400 1/800 sec with DSLR attached at prime focus.

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.
