OK... that makes some sense, BUT, I have moved the filter further from the sensor, not closer...
ATTACHED are some photos explaining it...
(The stickytape is a marker for how far into the focuser to put the tube)
I am yet to try out the new setup, as it is daytime.
I have noticed a triple image/reflection when looking through the filter, one red, one blue and one kind of normalish, red to one side, blue to the other
Any thoughts on that?
