Capturing a high resolution lunar image with an SV405CC OSC and AstroDMx Capture

An SVBONY SV405CC OSC fitted with an SVBONY IR/UV cut filter was placed at the Cassegrain focus of a Skymax 127 Maksutov that was mounted on a Celestron AVX GOTO mount.

The equipment used


AstroDmx Capture for Windows was used to capture two overlapping 1500-frame SER files of the 97.7% waxing Moon with the SV405CC uncooled.

The best 75% of the frames in the SER files were stacked in Autostakkert!, stitched into a 2-pane mosaic by Microsoft ICE, wavelet processed in Registax 6 and post-processed in the Gimp 2.10.30.

The SV405CC OSC is a high-resolution camera well suited to capturing high-resolution lunar images in addition to its primary role as a Deep Sky OSC.
