Quote:Aluminum barrel instead of brass? Thin-walled upper?And could the weight listed simply be wrong?11oz seems awfully light for a 2" 4-element design. That's almost 3 ounces lighter than the 3-element AstroTech 2" barlow.I bet it was meant to be 21 ounces.

Quote:Dave, I didn't see telecentric mentioned anywhere on Celestron's webpage. Did you assume that from teh 4-element design?
Quote:Is there another 4 element barlow design that is not telecentric?
Quote:>>this one is that it's weight is listed as only 11 ozThis barlow is indeed a lightweight. On our calibrated weighing scale, it weighs in at all of 10.2oz with the 1.25" adapter, and just 7.3oz without the adapter (weighed without the 2 plastic end caps)!Regards,Manishwww.AgenaAstro.com
Quote:A quick heads-up if I may. I own or have owned both the Axiom LX and Luminos EPs in various focal lengths. IMO the Luminos line is nowhere close to being in the same league as the Axiom LX. Appears Celestron changed manufactures for the Luminos line.I've looked at this barlow but the name engraved on the side frightened me off.

Jim, I remember reading your thread about the Luminos line, something about EOF brightening IIRC. It scared me off of the 19mm which I was looking forward to trying with its 20mm of ER. Hopefully the barlow will not share that same characteristic.
