Hmmm, don't know if this is what you're asking after, but this is how my shutter works on my wooden dome An aluminium flat bar is screwed to the main vertical spar of the dome, the shutter rides on it, with nylon blocks under to secure the shutter, quite weatherproof. The upper shutter is built up at the front to go over the lower shutter,seems to work well, the lower one just lifts off manually. Again, don't know if this is what you were asking about, but hope it helps. Huw

Here's my attempt at a dome, same kind of construction, feel free to ask away, I'll help where I can. Huw http://stargazerslounge.com/topic/112937-if-ikea-made-telescopes/page-5

Sorry if I'm being particularly dense, what filters did you buy? Huw

Olly, that is just showing off!!!!!!! I've just had one evening on Orion in the last four months. I'm not at all put off by this. Looking forwards to October though. Huw

This all looks very interesting. Anybody got it working with SGP, especially the temperature sensing? Ta Huw

I love it, with that mechanism in mind, why not add a drawbridge as well :grin: H
