Hi. I recently bought the book "The Dobsonian Telescope' (Kriege & Berry) because I'm very keen to have a crack at making a lightweight dob during 2014. I intend to use the 14" Skywatcher conical mirror and associated secondary that is in my current DIY dob. For the mirror support cell in my yet-to-be-built dob, I could do one of two things: (a) reuse the mirror support hardware in my current dob but IMO it's too heavy and closed; or (b) make something very simple, light and open. I'm keen on option (b), however, the book has a *lot* of info in making a mirror cell etc for a standard thick mirror, but nothing for a conical mirror. From what I've seen, conical mirror support cells are (comparatively) very simple but before I come up with my own design, I thought there might be someone who has travelled this path before me and could offer some advice, tips, hints, a design etc. Thanks, Alex.
