Weight of Eyepiece...

[magic77]

Ive finally narrowed down my widefiled eyepiece to an Adler 32mm or SW Panaview 32mm with the help from alot of you experts(thank you)..Last question i promise!!..Would the weight difference bewtween the 2 be a factor to consider?....Thanks.

Don't know if the weight difference will be much between the 2 but weight is an issue to consider with 2" EPs in a dob. The leverage of how far the tube extends above its axis means that a heavier weight would be needed to counteract it if it won't balance particularly at lower angles.

Those 2 weigh more or less the same. Quite light for 2" eyepieces actually - I have a Nagler 31mm that weighs around 1 kg !.

Thanks John..Do you know what kind of weight we are talking about with the 2 Eyepieces?...Not 1KG i hope!!...

You can sort the heavy eyepiece problem with a magnetic counterweight.

I keep mine in my eyepiece box, it attaches in a moment to fix balance

problems with my Dob.

When I had a SW Dob, it had a steel tube, so the magnetic counterweight

attached with no problem. When I changed to an OO Dob with its aluminium

tube, I fixed a couple of large steel washers to the tube end trim to give

an attachment point.

No - I think it's around half that. It's the ultra wide eyepieces such as the 31mm Nagler, 28mm UWAN and 31mm Axiom LX that are the heayweights - they need to have large pieces of glass in them to deliver the ultrawide, but well corrected, views - that's why they cost a packet as well !.
