This is the 9 point flotation cell, and will fit mirrors from 12.5" to 14.25" just by doing a simple adjustment. - These things are sorely missed in the ATM community, as they hold collimation REALLY well, what with their usage of heavy stamping die springs, that would hold a mirror of 5-10 times the weight; Kenneth did this right! - Your tube needs to be at least 13.5" I.D. to fit this cell, but it is a simple matter to use thick washers to shim it out to whatever larger diameter you may have.... - Suitable for any kind of Newt, whether Dob or EQ, as it will hold "positively" in any position!
I will ship this mirror cell to anywhere in the 50 states for $100. - PayPal only please on this as I need Christmas money - It's ok to use whatever credit card you have, even if you are not a member of PayPal at no extra charge, as I am a premier member of PayPal.
Thanks for looking, and have a great evening!
