Do you have a regular BKP telescope, not a PDS? Does it focus with an astrocamera? Because on a DSLR with a BKP, there's no focus.

Now I have a real mix of equipment! Specifically, this photo was taken with my old native spherical mirror, so it doesn’t have that sharpness. I’ve now installed a Chinese parabolic mirror. It’s become sharper. Regarding the astro camera—yes, it catches focus.
