Yes, I know I can buy one for a paltry hundred bux -- not to mention the fact that I have a working straight-through finder, but... I have a notion to make my...
Stay at the coarse grit until you get near the ROC you desire. Long strokes will shorten the ROC when the mirror is on top. Short strokes tend to make the...
RACI???? I assume that you mean a right angle finder by that bit of the compression of a phrase. A refracting telescope is a refracting telescope. Figure out...

Thanks for the comments on making my 22" Dob project an f:6. No one commented positively. So maybe I will take advantage of the pre-gen'd f:4.5 curve and...

Hey guys. I was sort of looking foward to my next project. I was thinking of a 10". I might make it out of thin plate since it is cheaper than pyrex and I...
The dry cleaner can't figure out how to remove the red rouge stains from my coat sleeve. I suggested oxalic acid, but he refuses to consider it. Same as...
Take about 1/4 teaspoon of that black rouge, and sprinkle it in strategic spots in the ladies room, and see what happens. ... From: atm_free@yahoogroups.com...

I'm thinking the 1.25" is my best bet. Thinner than 1.6" but I'll have to worry less about support when making the mirror and in use compared to 1". I don't...
Every time you double the area, you must double the thickness. So you can imagine the series of numbers, 4, 5.6, 8, 11, 16, 22, just like camera f-stops,...

I'd easily go to a 3/4" blank without any fears as I've already done some 12" mirrors that thick and one guy is working on a 17" that thick right now. A 1/2"...
