As a astro-newb and soon-to-be owner of an 8" Dob (which for those not
familiar, can accommodate either 1.25 or 2" eyepieces & accessories), I
am clueless as to the advantages and disadvantages between the two, and
hence, also clueless into which size future investments should be made.

I guess one could say I have put the cart before the horse in that I
have already made purchases for 1.25" accessories, e.g. filters and
barlow... I did this because it seemed money well spent; 5 filters and
barlow w/ shipping for $90. In my mind, I was maximizing my abilities
with what accessories where coming stock with the Dob.

However, if 2" is "noticeably superior", then I am "destined" to resort
to 2" (and all necessary, associated, accessories), ergo making all
current 1.25" purchases - wasteful. Of course I could send back the
1.25" accessories and exchange them for 2", but then I'd have to
purchase 2" eye pieces as well; spending more money. Is it worth it?

Please make up my mind for me.....
