[APML] Internal Reflections with a JMI focuser on my SCT.

[Bryan & Kristin Bradley <bradley3@optonline.net>]

I'm wondering if anybody has any thoughts or ideas of why I'm getting
internal reflections (bright arcs) since incorporating a JMI NGF-S focuser.
I have a 1600mm SCT(10" f/6.3), and am now getting these bright arcs in my
timed exposures from bright stars outside my 35mm field.  I definitely have
the internal light shield which came with the NGFS focuser which is supposed
to correct this issue.  By removing the focuser I have obviously eliminated
the issue.  But I'd really like to use the focuser due to mirror shift
issues in my SCT.

Any help would be appreciated.

Sincerely,
Bryan Bradley
