Hi James-
I've used the Hyperstar on my C-14, and it is a fussy beast - collimation has
to be spot on - that might be the cause for the corner imperfections. The
streak seems to line up with the bright star at bottom. That might be the
cause... Both great images!
One comment - since in the Hyperstar, like a Schmidt camera, the camera is
inside the optical path, the image needs to be flipped in one axis or another
to keep correct orientation as it appears in the sky...
-Dean

Subject: [AZ-Observing] The Horsehead with Celestron C-11 Primary and Hyperstar
imaging
I decided to take two images of the famous Horsehead nebula. One wide
angle that show the region around the horsehead, and another zoomed into
the horsehead itself. Both images were taken with the same
telescope(Celestron C-11). The wide angle with the Starizona Hyperstar
configuration.
