Great! I haven't had the time to make my own Duncan mask, so would you please provide a link to your web site.

Ditto! I'd love to pick one up for a C11.

No web site, send me a PM here. I found a web site was costing me more than I was making, this is a very small part time business. I will need dimensions of your scope in order to cut one. Scopes over 10 inches I have to farm out the cutting to someone with a larger laser and it isn't cheap.

I have a friend who has a new 3D printer. I will see if we can figure out how to print one of these Duncan masks for my C8 and C11... already printed out Bahtinov masks, so should not be that difficult.

Ideally, if anyone has a .svg file with exact dimensions for the Duncan mask, that would make it easier, otherwise I will use the drawings from a few of the posts on this thread. ( I assume there is no "Duncan Mask" generator on the web? http://astrojargon.net/MaskGenerator.aspx)

Bump.

I got an email recently from someone asking if I could add Duncan masks to my lineup, so I wanted to see if that would be a useful service to provide to the community. I've read some conflicting posts here about people being able to get results with them, and I've never owned an SCT so I don't know if methods like Greg Nowell's SGCD are easier/better. I don't want to sell something to people that isn't going to work well.

Mary B. (Echo Astronomy and Electronics) in a previous post stated that these masks can be laser cut up to 10" in diameter...
I'm wondering if a larger diameter disc can be used to "stop-down" a larger diameter scope to 10" and still work? I'm thinking here of my C-14.
