[Barnacle (Bill)]

Hi Matt and Raymo,

I removed the objective lens and focuser tonight.

I then nudged the baffle with a pole, it won’t budge. I then managed to hammer the baffle with the same pole and dislodged it from the scope tube. The baffle was not welded nor spot glued.

I then re-inserted the baffle closer to the focuser end, and put the objective lens and focuser back in, then flashlight tested the scope to ensure it is now showing the full 70mm aperture.

Star testing tonight with Sirius does seem to indicate the lens is somewhat out of alignment, as it shows a little astigmatism which it did not before. Maybe I have not placed the objective lens back in properly or the focuser got out of alignment. Astigmatism, as I understand it, should not be correctable by stopping down a scope.

As the Moon is not around at the time of testing, I can’t test the scope for limb colour, but Jupiter is fine at 77x using 6.5mm eyepiece.

I will update more when I experiment with it further with more observations.

Thanks.

Kind regards,

Bill
