Quote:Why do you feel the need to standardize focuser sizes?

Quote: And ultimately, those 2.5" focusers or 3.5" focusers are all designed just to be able to make the best use of the same 2" eyepieces or cameras that one might use with an SCT or reflector.
Quote:You can bring it up in a year or two years, or five years, but until we standardize on a specific telescope design, it doesn't make sense to have a standardized eyepiece size.
Quote:I posted this subject about a year ago and thought to bring it up again. The "standardization" of eyepiece barrels and focusers.Currently there are 0.965", 1.25", 2" and 2.7" focusers along with some newer 3.5" and 4". Asking if we really need so many? ES is currently proposing a 3" barrel for their new 30mm eyepiece. Adding the 3" gives us 7 standards. Do we really need this many?So, how many should we have?2.7" and 3" seem rather redundant as does 3.5" and 4"I would suggest 1.25", 2", 3" and 4"If somehow the community could get together and ask manufacturers to also get together and agree on a standard, there would be no need for many odd sizes and all kinds of adaptors.Your thoughts please?

Quote:Hmm. I'm having trouble making sense of this statement Eddgie.
