[strike]ATTENTION MOD FANS!
Due to a change in solar telescope plans, I am selling new and unused 6 inch folded achromatic telescope optical components.
Here's what you could accomplish (see bottom of page: http://www.istar-optical.com/istar_076.htm ):
Here are the components:
ISTAR Optical 150/1500 fully multi-coated 6 inch f 10 Achromatic Objective in CNC machined cell ($519 new).
ISTAR Optical CNC machined Counter Cell for the above ($227 new).
Both as a package for [strike]$675[/strike] $600 and will include push-pull stainless steel adjustment cap-head metric bolts, the ISTAR test report, and cell/counter cell schematics.[/strike] BOTH ARE PENDING
STILL available: two Zerodur 1/20 wave aluminized optical flats of 3 and 4 inches in diameter that were to be used to produce a compact folded refractor design.
3 inch $200.
4 inch $300.
Both for $450
[strike]Package price for all is $1100, and I will pick up shipping in CONUS.[/strike]
Payment via bank draft, USPS money order, or personal check (must clear before shipment).
If you wold like a collimator lens (new) for a 60 mm aperture telescope mod, and/or a field lens (which is a surplus used lens) to optimize the collimated beam, these are available for $150:

Re: 6 Inch Refractor Components
Hi Colin,
The collimator is an achromat with a 600 mm FL, the field lens is a singlet DCX, with a 535 mm FL.
