Trade My 80mm Flourite Triplet APO for your superb 10" F5 mirror

[lhansen (Lars)]

I've got a LOMO manufactured 80mm flourite triplet APO in a WO black tube with a single speed Crayfor focuser for sale ($900) or trade.

I need a superlative 10" F5 mirror, either pyrex or something better such as cervit etc. Must have a demonstrable PV of better than 1/10 Lamda Wave Front (not surface) or at least 1/30 Lamda RMS - Strehl of .96 or better.

We can talk value of respective goods if you are interested.

Thanks for looking

Lars
