Re: A question about a AP155 EDFS with the 2.7" focuser

I have been looking into the spacing of some of the older AP field flatteners. Many were configured for the Pentax 6x7 system. IN that case 86.5 mm is close to the 86.4 +/- 2.5 mm I thought was the correct spacing. I found this on an old thread that was forward from the Yahoo group into the AP User group).
