Lunar imaging with the SV205C camera

The SC205C camera also goes under the same name as its predecessor, the SV205.

The original SV205 was a challenging camera suffering badly from pixel vignetting that was largely due to the fact that its sensor was intended for tablets or phones and not telescopes. That having been said, we were able to obtain some very good lunar images with the original SV205 by doing real time flatfield correction and conversion to grey-scale in AstroDMx Capture.

The SV205C (the new SV205) is a much better camera that does not suffer from the pixel vignetting shown by the original version. It is still basically an 8MP camera and has a Sony STARVIS IMX415 backlit sensor with 1.45 micron square pixels.

There have been some issues with this camera not working in macOS and Nicola is currently working on this.

We tested the camera using AstroDMx Capture for Linux.

The SV205C was mounted at the focus of a Skymax 127 Maksutov which was mounted on a Celestron AVX GOTO mount.

1000-frame SER files were captured of selected regions of the Moon with AstroDMx Capture.

The best 90% of frames in the SER files were stacked in Autostakkert! , wavelet processed in waveSharp and post processed in the GIMP 2.10.

The SV205C is a much easier camera to use for lunar imaging than the original version. It is also now at a better price point for a potential purchaser. 

Nicola has implemented the SV205C in AstroDMx Capture for Apple Silicon. At the moment it is proving intractable in macOS x86-64 but Nicola is working on it.
