Bahtinov Mask

Posted By Steve Mathis
It looks plenty good! I've made four so far, three for me and one for a buddy. The design is forgiving. I've tried Hartmann masks and have a Stiletto, and the Bahtinov mask beats 'em both. It is easy to use, and is very sensitive to small changes in the focus position.. A while back I posted a question here about the physics behind the recommended width of the spaces, but didn't get any response. When you get a chance to try it, let us know what you think.

Great images, Robert! And good timing, too. I snapped this last week, and wasn't sure who these guys were. This is a YRW, too, I think?

Rho Ophiuchi done at TSP

That is great, Chris. Is that an older 180mm f/2.8 ED, or a newer version? Were you wide open? Thanks.

Morning Sentinel

Very nice. The red/green color contrast and shallow depth of field make him really pop!

Hmmmm. Why does that seem sort of creepy to me, big brother?
