Re: PFLAT4 and Megrez 120 scope
- Hi all,I sent an e-mail to William Optics on the subject and got the following reply.Looks like experimenting is the way to go.Gordon
WE would suggest you to take many different photo shots with FlatIV and keep changing the
setting b/w 66 and 86mm, then you can choose the best shot and that will be the best suited
setting for your setup.
I have a Megrez 120 and a field Flattener 4. Would you be able to advise the optimum setting for the FF4 please?
I am very satisfied with both of these high quality products. Well done William Opitcs.
Did your Baader varilock spacers work for you?

From the WO website the 76.8mm is for 98FLT as the scope gets larger(110FLT=73.5mm, 132FLT=71.5) the distance decreases, however the site does not list the distance for the Megrez 120 from what I saw. Just to be clear you are talking about WO Flat-IV? If so the spacer/extender you would need is flexable when set at 66 the glass is 14.1mm 76 24.1mm and 86 34.8mm. It would then seem your setup as:

> So your setup is roughly 40.49mm-61.19mm Since there is no distance that I could find on the WO site for your scope using the middle of the FLT110&132 72.5 roughly...it would seem that a spacer/extender in the range of 11-32mm.
