Greetings!
\nWe have a 9.25″ full aperture baader solar film filter, in a neat aircore mount that just force fits inside the rim of the Celestron C9.25 Schmidt Cassegrain telescope.
\nAfter trying to use it for imaging, we discovered that is is so much overkill that we got no useable images. The full aperture brings in sooo much light that the zwo asi585mc camera was at its minimum exposure and everything was still overexposed.<\/p>\n

So then we built another aircore layer with two 2″ subaperture holes to act as a mask.
\nThen we needed safe storage for it and built this aircore storage based on the one built for the 10″ Douglas dob 15-20 years ago.

We will add another image of the solar filter itself.. the smaller inner bottom ring is what force fits into the end of the C9.25, then the film then the top ring, which overlaps the C9.25 end.<\/p>\n","protected":false},"excerpt":{"rendered":"
