Serious about adding a refractor to my Zero collection

Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

I just got back my ZSFD 80mm from Arief. Sure, lets do a 3-way shoot-out between the TV85, ZSFD80 & the CZ10" (carbon tube or teleport) mask-down to 80mm. Both Liuming & I are very keen to test this and find out the results.

When the 10" teleport are masked down to 80mm, the obstruction ratio will increase :) It may reduce contrast.

There will be no obstruction... it'll act like an off axis reflector... :)

Have a nice ay.
