this is my bahtinov mask for c9.25 its made out of aluminum 1.5mm mask created through http://astrojargon.net/default.aspx processed through incscape - great free vector software laser cut at local athens greece shop - thank you periklis, viky and dimitri 10 minutes work - AMAZING PRECISION in focusing cost = 20 euros hartmann masks are funny compared to this if you intend to make one dont forget to include 3 ears at 270/0/90 degrees (so that the mask stays on the scope and you dont have to hold it) will post astrophotos with dsi II as soon as the weather clears great stuff you can find in cloudy nights, i'm excited! achilleas
