Hi everyone!
There is a known issue with Celestron EdgeHD scopes: a nearby bright star produces rays of scattered light. It looks like this:
Little Dipper - An Asterism in Perseus
According to my measurements a bright star should be approximately from 27 to 35 acrmins from the center of the field of view to produce this effect in EdgeHD 11 scope.
Here is an animation of frames (full frame sensor) where a 2m star Mirach is positioned from 21 to 35 arcmins from the FOV center. As you can see, frames at 29, 31 and 33 arcmins are affected:
And the same frames in a column:
I hope that this will be helpful. I take this into account when I frame targets and try to make sure that no bright stars are located in the "bad" range.
CS,
Vitali
