Re: [APML] Custom Ring

[Jerry Lodriguss <jml@astropix.com>]

Hi Rob,

That's exactly the same lens I have, I didn't think the Losmandy 125 would 
fit it though, I measured it at 124mm and I didn't think 1mm was enough 
space. It looks like you have plenty enough room though.

I gather you have to put the back end of the lens in first and then attach 
the ST10 because of the lip in the front of the lens that holds the lens 
shade on?

Did you have to have a custom block machined as a spacer between the ring 
and the dovetail plate?

Do you have any problems with the Delrin tips?

Are you tightening the bolts down on the rubber grip, the focus lock 
buttons are right in the way where there is no rubber I noticed.

Are you also bolting the lens down at the tripod socket?

Did you get Scott to split up a pair and sell you one 125 and one 150?

Thanks for your help.

Jerry
