The terminator of the 98.5% waxing, gibbous Moon with AstroDMx Capture, a SVBONY SV105 camera and a Bresser Messier-AR-102XS ED refractor

An SVBONY SV105 camera was fitted with a Baader green continuum filter and a x2 Barlow using the refractor at f/9. AstroDMx Capture for Linux was used to capture 4 overlapping, unsaturated, 1500 frame SER files with real-time flat-field correction of the terminator of the 98.5% waxing Moon. The best 75% of the frames in each of the SER files were stacked in Autostakkert! 3, wavelet processed in Registax 5.1 and stitched into a mosaic by Microsoft ICE, all running in Wine. The final image was post processed in the Gimp 2.9.



Using the Barlow still allowed significant oversampling with the 3 micron pixels of the SV105. The 10nm bandpass continuum filter in the middle of the visible, provided light reduction for the very sensitive camera, and eliminates any possible dispersion, notwithstanding the ED objective of the telescope
