My 16mm Nagler is my most used Nagler. My 12 least - or at least tied with the 4.8.

Finder scope question (planetary)Posted By Adam Albino |
Apples and oranges.... typically you want a short FL OTA as a "finder" - IE low power wide fields, and a long FL high power scope for planetary. The MC's are usually long FL and would not make good "finder scopes" but some make good Guide scopes for Astrophoto work (although Mirror flop can kill you unless you get a good one...).

Condition? Where are the focusers? What else is missing? Lens?

Keep in mind these look like the Vixen ED's that Orion carried a few years ago - not the Orion/Synta 80mm ED that they currently carry. The Vixens are worth quite a bit more. You do not state the size - but assume they are the 102mm (that's what they look like to me) - my guess is if the lens is in excellent condition 3-500 each....With that said, the "market" would be the ultimate deturmination - and no better place then the "Auction" function here on A-mart.

I believe the Vixen is a doublet - no?

I have the ZS110 - which has the same TMB lens as the FLT110. I can attest to the color correction being excellent. If you go to the WO site you will see the color charts.

Although its been many years since I tried them, this would make an exceptional finder chart for those globulars of M31....

field flattener educationPosted By Adam Albino |
Yes you can - but usually FF are designed to work in specific FL ranges - So you'd have to "match" to meet your scope. I've used the TV one in a WO scope, and the Celestron SCT one in a WO scope - both worked. BTW the Celeston SCT one (and I assume the Meade one also) seems to have quite a wide range of FL capabilities...your 925mm range is pretty long and may not be much of an advantage - might want to see before you buy...
