T didn't you do one around 50mm (camera lens), how did that work? Thinking of milky way shots this summer. Spike, another resource:

I've bought a few different ones there. Marc

I did...four to be exact...out of paper and cardboard! They work very well too.

That is what perfect focus looks like my friend!

Spike, thanks. The one thing w/the mask there isn't any guessing on focus, it is either on or it isn't (especially when the atmosphere is turbulent). The only thing is I'm not sure how well it would do w/your planet work. Might be fine, but don't know. I think Backyard Eos has focus metrics (not positive) which might be better(?). Somebody on this site is using it. Marc

"seconds" not second....

Hey Marc, I hear ya, I am a recent convert to the mask. Takes literally second and according to the stats in the software it is dead on. Can't beat if for a piece of paper taped to a cardboard backing!
