Would a reticle for a spotter be sufficient if it was SFP vs FFP.

[QUOTE="bruce_ventura, post: 954200, member: 34084"] Well then it seems to me that this a moot question. A simple telescope has an inverted image. Most rifle scopes use an erector tube (essentially a second telescope) to invert the image a second time. The erector tube creates the second focal plane. All of the spotting scopes I can think of use a prism to erect the image, and there is no second focal plane. The reticle on a conventional spotting scope must be in the FFP location. [/QUOTE]
