Description

Only 13 subs taken by the Piggy Back camera due to a technical problem. Very hard to correct turkis color cast from the Astronomic CLS-ccd filter. Anyone else having this problem?

One may notice the border between the full format view with the Piggy Back and the smaller FOV from Sony a500. The outer edge does not show colors since it is from unmodified Sony a7. Looking at bigger stars one can see diffraction spikes from the aperture lamelles of the Takumar lens. 

With main telescope 83 subs through the l-enhance. The red color is from Ha and the blue from Oiii and perhaps Hb.
