Webbed Back mirror blanks

Posted By Lawrence Loe

Has anyone ever used these type blanks?

I just happened to find this page while looking for pyrex blanks on the web. Wouldn't the "web" wear thru the front somehow?

Thanks,

Larry

Where do you get your trusses from?

I am thinking of building a truss dob from my DS 16 inch scope.
Where can you get inexpensive tubes for a truss dob?

Thanks

What am I supposed to see......

When I Aim my 12" scope at Jupiter? Even with 8mm EP I can barely make put the bands. I cannot see the red spot at all as I can just barely see the bands.

Would a properly collimated scope see better?

all I can guess is that collination is bad.

Help?
