Focault tester slitless do I need it to tilt?

Posted By Steven Gorkowski
Thanks everyone for the help. I will add the adjustment to the tester. Yes I am using a spring as a return spring. And the rail really keeps side play down to basically nothing. I added a picture Bob of the spring setup. Looking for a weaker one when I get to a bigger city.

Thanks

Alum vs. Resin vs. Fiber tubes - what's best?

Posted By Steven Gorkowski
The diagonal does sounds on the edge mine is f7.8 and the program for calculating mine told me 1 1/8 inch for 10 inch tube std focuser as a min size. You maybe able to get it to work with low profile focuser and smaller tube. I went with the 1 1/8 1/20 wave in surplus shack. I will be at 9.5 inch tube maybe a tad smaller.I will be flocking the tube so I wanted to give me some extra space. Mine will be a 8 sided wood tube and brass trim.Using curled Walnut and Maple.

Keep us posted how the small mirror works.

Coating disaster

Posted By Steven Gorkowski
They are feeding you bull. Chips are caused by miss handling. I would tell them to fix it or replace it. If you paid on credit card get your money back by calling credit card company.Save this picture so if you have to talk to a lawyer you have proof of the damage they caused.

Sorry you had problems

Spherometer Necessary?

Posted By Steven Gorkowski
Spherometer is great for finding or staying close to your target f#.I use one for this reason. You can change the F# by some degree by the amount of time the tool is on top or amount of time the mirror is on top.

Hi Gregg

mirror re-coating

Posted By Steven Gorkowski
Clausing has done all my coatings. My 8" took 1 month to get back and my matched 6" mirrors took 4 days. There prices are almost 1/2 that of Spectrum for the coating I used and they have been coating for many years. This 8" mirror I have had for 2 years and looks as good as it did when it was coated. Here is the picture of my 8".

good luck

Eyepieces for Orion XT8

Posted By Steven Gorkowski
The group has great ideas but please also look at Rini eyepieces. I have a pair 30mm Rini and love them. They sell for $30 each. The web site for his eyepieces is http://proptics.ieasysite.com/paul_rini_scientific_010.htm
