Update on the Chinet mask - absolutely awesome! I worked for about 15 minutes to focus the old-fashioned way and thought I was really close - I wasn't. The "spikes" were very clear with the mask and I could easily see movement toward focus. So, for those of you who want to just whip out a Q&D mask to check this out, don't worry about getting the cuts straight or the correct spacing initially. The mask design is very robust and will overcome deviations from perfection quite well. If you look at my mask in a previous post, you'll see what I'm talking about. Looks like I'll be searching for someone to create acrylic masks for my refractors. Again, thanks to all who have contributed to this thread. BTW, I used Alpheratz as my focus star (2.06mag)
