Mark ,how do you think the time line of my mirror to this new Feathertouch Paracorr focuser will go. Worth waiting to order one?

I look forward to the release of the Parracor V2 this year that will be optimised for F3 to F4 scopes and deliver a flatter field than the V1 , whose design is about 20 years old now. Feathertouch focussers will be marketing a special version with the V2 Parracor lens screwed into the focus tube base, that will obviate the need for the 'tunable' top on the Paracor. Just put any eyepiece in and it will automatically be at the correct distance from the coma correcting lens for optimal performance.
