Moon 66% - 6 panel mosaic - 20220710

In parallel to my run on the moon to capture the sequence of my previous images with the TS94 scope, I also wanted to create a new mosaic image of the moon with my TS140 scope. Last time, I used a red filter, this time a green filter was applied. I get the impression that the red filter gives a bit more contrast, bringing out the detail a little better. With panels at 720p, through various drizzle and up-scaling techniques, I ended up with a 9k x 9k image, hope the number of pixels is worth the detail they should show (although, I had to downscale it again to get it uploaded). With its 66% phase, the image shows the Copernicus crater quite nicely in fine detail.

However, compared to my previous mosiac of the half moon, compiling this mosaic did present a lot more challenges. The panels of the illuminated first half were so bright, compared to the faint outflow into the dark night-side, that the merge tended to tone down this edge in such a way that all faint detail would’ve been lost. I applied a couple of masking techniques to counter this, to preserve the faint edge near the night-side and avoid overblowing the sun-lit day side of the moon.

I think I’ve achieved a reasonable blend, without skewing the overall luminosity too much. Happy with the result I’ve achieved and the new learning gained …

Processing the moon does present itself with a different set of challenges compared to faint nebula. No surprises … 😉

Clear Skies everybody! 🤩✨🔭

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.
