Ad Astra Observatory

A,

Just ordered a 3/4” travel drawtube from Moonlite. I have to wait for
their next CNC run to get it, but he’s only charging me $50 for it. I
should be able to eliminate the focuser as a culprit in vignetting.

I’m pretty sure it’s the MPCC. But I’d rather do flats than take the

MPCC out of the image train. (:
