meade astrometric and celestron microguide
just a quick question about the microguide and astrmetric EPs.... obviously measurements made with these EP are going to be different depending on what fl telescope is used right?
1200mm fl @ 120 times.
2000mm fl @ 166 times.
the measurements in arc seconds are going to show as different for each of the scopes... or am i wrong?
and if i am right are these EPs designed to work at a specific focal length?
