85% Waning Moon

With one EQ mount returning to Celestron for warranty and the other now sporting a bad power board, I've been trying to enjoy shooting the solar system using my Alt/Az mount. Shooting some of the first objects but with a few years of experience and processing techniques has been an interesting comparison.

- Stacked in PSCS6 using automatic alignment and median stacking. Each of the 2 mosaic pieces contains 300 frames. Once each stack was flattened, the two frames were combined with layer masks into the full Lunar image

Processing Luminance:

- PixInsight RestorationFilter for Deconvolution / Sharpening

- A few passes of Unsharp mask in small pixel values (Decon did most the work really)

- 2 passes of ACDNR for Noise Reduction

- HDRMultiscaleTransform to deepen contrast, especially around the Copernicus crater area

- Curves edits for Contrast

Processing Color:

- Noise analysis in PixInsight found R channel to be the least noisy

- Ran Linear Fit process in PI to match G and B to R channel

- In PSCS6, several passes of Saturation increases and decreases using a continually inverting luminance mask to color darker regions while keeping the highlands under control

Combined / Final Processing:

- Split channels of Color image, used PixInsight LGRB process to combine color and luminance image

- Final curves adjustments completed in Photoshop to reduce background brightness

- Resized and added signature

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.
