Lunar Landscapes: Rima Hadley (MrCrazyPhysicist)

Lunar Landscapes: Rima Hadley

Acquisition type: Lucky imaging

Finally, I have some time to work on my 216 Gb of lunar data, captured on the morning of Sep 6th 2023 here in Northern Germany. According to the star test using Capella before the planetary and lunar imaging session, I think the seeing was fair-good (~ 6-7 on the Pickering Scale). Processing of the G data is based on the tutorials Processing Lunar images with Photoshop by Damian Peach and Imaging the Moon: Capture and Process, Stack, Sharpen by Refreshing Views. Let 's begin with Rima Hadley located west of the Montes Apenninus.

If you want to process the data yourself, I uploaded the raw stack straight out of AS!3 here.

Celestron C14 Edge HD @ f=6650 mm (F/28), res = 0.09"/px
+ Celestron CGE Pro mount
+ Celestron EF
+ ZWO ASI 290 MM
+ Baader 2x VIP Barlow
+ ZWO EFW
+ Astronomik G filter
+ Tempest Cooler
+ Omegon Dew Heater
+ Astrozap Dew Shield for C 14

Very short imaging train: I simply screwed the Baader VIP Barlow into the nose piece of the ZWO EFW. However, the small pixel size of the ZWO ASI 290 MM leads to a pixel scale of 0.09"/px at a reasonable f-ratio of f/28.

Autostakkert!3:
- Stacking 500 of 5000 frames
- Image Stabilization: Surface, Improved Tracking, Cropped
- Quality Estimator: Laplace, Noise Robust 5, Local
- Reference Frame: Autosize
- Minimum AP size = 104, Min Bright = 20, Multi-Scale

Registax:
- histogram correction to increase the brightness of the underexposed image
- wavelet sharpening using Wavelet filter Gaussian, step increment = 0, no linked wavelets:
layer 2 - 100, denoise & sharpen

Photoshop CS2:
- image crop
- level corrections to clip the black levels of the shadows
- unsharp mask (amount: 21%, radius: 1.9 px)
- sharpen
- slight noise reduction

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.
