Meade makes their own aluminum dew sheilds for their SCTs.

QUESTION: Respective of size, will their SCT dew shields fit all of their SCT models?

I have ordered a new 10" LX90-LNT, and I'm wondering if I buy a Meade second-hand dew shield designed for one of their 10" SCTs, will it fit mine?

Thanks and regards,

Sam, there is a theory going around that metal dew sheilds don't work as well as plastic or foam because they act as heat sinks and cool the corrector faster. I really don't know if this has been tested or an urban myth, but just FYI.

I have a JMI 8" SCT shield for a Meade LX90, it is metal but lined on the inside with black felt. It at least triples the time I have to observe with, but something about the design tells me its not worth $130, LOL. It's not bad, just not THAT good. And the fit is just fine, there are three adjustable screws. But I think one can make something of equal or better quality, or buy a synthetic shield for much less.

I have an Orion dew shield for my 10" LX200 and it was about $32 shipped.

Gentlemen-
For the last 9 years i used a "flex" felt-lined dewshield... until fatigued, it finally cracked beyond functionality (= i ran outta duck tape ;)). So i've just recently constructed my own shield using "Reflectix" lined with "ScopeStuff" black adhesive-backed flocking. I've meant to do a quickie write-up post on it, but haven't had the time. So far it's worked really well, but is so light-weight i'm having to re-balance my rig! My only concern is it's durability... yes-it's somewhat less expensive than a typical "flex" shield, but the minimum material you end up purchasing will build two shields, and even with TWO of 'em, they may not outlast the lifespan of a single 9-year "flex" unit. Only time will tell. But at least i got to play with sharp instruments :scared: & that reeeelly cool flocking-felt! :woot: That alone was worth the price of admission :lol:

Great idea Mike.

I use a flex shield to ward off stray light.. no humidity up here, but one neighbor has a pesky light. The thing is like 20 acres away but I swear it's pointing right at me. I was thinking of putting a pole and small square about 100 feet from my observatory to block it. Would look silly, but I bet it would work!

Perhaps you should make a dozen or so of your lightweight dew shields and sell them here!

most of the Meade scopes use similar ota's thus an lx90 will fit a lx200 ..the aluminum shield functions to prevent the dew from reaching the lens..it acts more like an umbrella then anything..when i mounted a top rail and guide scope on mine the flex Shields would not fit without notching them...that said the aluminum shields do not fold flat( at least not more then once , then it stays that way)
but they look quite sharp. also the may make the scope quite nose heavy so counter weights may be in the future

Joel,

I also have an Orion flexible dew shield for a 10". Granted the price was low; but, the thing weighs A TON :foreheadslap: !!!
