The Moon with new tools


A Player One Mars-C II OSC CMOS camera was attached to a William Optics 81mm APO refractor with 0.8 reducer/flattener and an IR/UV cut filter. The scope was mounted on a Celestron AVX mount that was controlled by AstroDMx Capture via an INDI server.

AstroDMx Capture  was used to capture two 1500-frame SER files that overlapped to cover the whole 95% lunar disk.




Autostakkert! Was used to stack the best 80% of frames from each SER file. The resulting images were wavelet sharpened in the new, cross-platform wavelet processor waveSharp by Cor Berrevoets the author of Registax in close collaboration with Grant Blair; Michael Owen; Filip Szczerek; Cheng-Yang Tan and Don Capone.

The two wavelet sharpened images were combined into a single image, rotated and cropped using PhotoPad Image Editor. There is a free version by NCH Software.

The image was then cropped and post processed in PhotoPad Image Editor.

PhotoPad Image Editor is not a new program but it is not one that one naturally associates with Astronomical image processing. It is a Windows program by NCH Software and mostly works in Wine. The free version does everything that was done here and the license is low cost.


On the other hand, waveSharp is new software that extends the Registax wavelet processor into a new form and very importantly, as cross platform software that has versions for Windows, Linux and macOS.


waveSharp and AstroDMx Capture are just two examples of software for Astronomical imaging being made natively available for platforms such as Linux and macOS without having to use Wine.
