This University Optics cell was purchased for an 8" f/7 Cave mirror that I had hoped to aquire but soon realized it was really too close in FL to my 10" f/5 that I already have. So instead of going down in aperature I've got the Fever and will be going up and have no use for the cell. $24.00 with $6.00 added for s/h to the CONUS. I prefer Paypal but will accept either a cashiers check or postal money order if arm is twisted sufficiently.
(From University's site:
• INFINITELY ADJUSTABLE TO YOUR TUBE
• FASTEST COOL DOWN
• ADJUSTMENT LOCKING SCREWS
• CELLULAR RUBBER COATING
• SAND-CAST ALUMINUM
Twenty five years ago we started with a clean sheet of paper and came up with the University Expand-O-Cell. This new concept allowed an extremely light cell that lets your mirror reach thermal equilibrium faster than any design on the market. These cells are 100% sand-cast aluminum. No moisture absorbing materials used anywhere in the construction. The cell fastens to your tube with large 3/8 - 16" threaded stock, not tiny screws found on some competitors' designs. The mirror is held in the cell by solid brass mirror clips. The mirror carrier is spring loaded for precise adjustments. The mirror rests on cellular rubber pads (9 pad suspension in the 10", 12.5", 13.1" and 16" models). Join the thousands of satisfied users and order yours today! Made in the U.S.A.
