hm ph: 520-586-2244 I had six small L-brackets on the filter holder arranged
around the perimeter of my 13-in Dobsonian telescope tube securely holding it
onto the telescope. The trouble was that it was fairly heavy and I had to
scootch the telescope down aways in the saddle which caused the mirror-end to
hit the Dobsonian base. Fortunately the sun was well past zenith (which I
couldn't have reached with that setup) by the start of the transit and all went
well. I had to put cardboard shims in my altitude bearings to increase the
friction to keep the telescope from being blown around too much. It worked
fine. I viewed the ingress contact points 1 and 2 at about 100x and allowed
Venus to be entirely inside the disk of the sun before I removed the filter and
moved it to my 20x100 binoculars for a stereo view that was simply magnificent.
Clear skies,
Wayne (aka Mr. Galaxy)

I know how you feel about the filter blowing off, probably being sucked
off by the wind blowing over it. This is what I like about the Lunt
Wedge. There is no filter at the objective end to blow off. When I had a
11" Thousand Oaks filter on my 12.5" Dall-Kirkham, I had made up two
aluminum brackets equidistant apart that held the filter down so there
was no chance of it blowing off.
