Achromat for Redrock M2

[robot909]

Redrock micro sells a Achromat for the M2 and I was curious if using a Century Precision Optics' Achromatic Diopter would work as good (they come in three versions 1.6 2.0 and 2.6 magnification). Anyone use the Centry optics with the M2?

thanks

Won't work. The RR one is I think X10 mag. Why not buy te one from RR. Its guarenteed to work.

I have the century 2.6 and it indeed will not work. It's a beautifull piece of glass, and in my opinion far better than the one RR supplies, however it just isn't powerfull enough. You need at least a 3.0 diopter to get the job done.

Century Precision Optics sells 58mm a +7 Achromatic Diopter as well. It is $220 though and you would need the step up/down rings as well. I have no clue if that is enough for the M2 though.

I bought the RR 55mm +10 to replace my Century Optics +7 and, other than not having to zoom in as much and the price, I haven't noticed any difference between the two.
