Wow, I can't believe I read an entire 22-page thread, but this one has been great! Yesterday I used the wisdom gathered here to create a Bahtinov mask for my 4" Stellarvue using black cardstock and an embroider hoop. The results were stunning! Perfect visual focus in just a few seconds. Unfortunately it was cloudy last night here in Phoenix so I had only a few minutes to try it out. I'll try it out again tonight, this time with the camera. My big thanks to out to everyone who had a hand in putting this thread together!
