The glass is the only important portion of the eyepiece...the rest is just support.

You don't really mean that, do you?


--------------------------------------------------------------------------------



Yes I do.

It is true.





Well then, perhaps you could tell me which is the only important component in a simple peanut butter sandwich: the peanut butter or the bread? Would you contend that the bread is just there for support?

While you're pondering these weighty questions, take apart your favorite eyepiece. Discard all of those heavy, bulky and unimportant metal parts and stack up only the essential glass elements on your diagonal.

Let us know how that works out...




It sounds like you are trying to pick a fight...if so go else where.

In your analogy of the peanut butter sandwich, I would be keeping the peanut butter (maybe going with the lite spread) and definitely go with a lighter weight bread instead of a heavier weight bread.

The result would be a better sandwich. ;<)




I don't think anybody is trying to pick a fight, but I think there is some frustration (speaking for myself at least) that you seem unwilling to provide some more substantive descriptions of where the weight of eyepieces has given you problems. Even an example would be helpful.

You mentioned you have several scopes earlier. Could you give an example of a specific telescope and specific eyepiece that in combination provide a problem due to the weight of the eyepiece?

With regards to your suggestion that all eyepieces are the same weight, I don't think that is realistic. Eyepieces are not designed for weight, they are designed for specific optical purposes and the weight is a byproduct of the manufacturers design. Change the weight and you change the design.

Nor are plastic lenses a realistic solution. If plastic was feasible as a high quality optical product we'd all be able to get great optics for very low cost.

I'm not unsympathetic to your concerns about weight. It limits which eyepieces I can purchase. But we have to be realistic too.
