Which is the better of my 2 title telescopes?

 

Are there any other lightweight 70mm ED models. My Pronto is too heavy for the older relative who I share it with, so I wish to get him a lighter refractor as a replacement.

I had the SW 72ED and it was light enough to use on a camera tripod.

My Orion 80ED is perfectly manageable on a Manfrotto MK290LTA3-V video tripod.

According to online stats, a Vixen ED70 SS OTA weighs 4.8lb, and a SW 72ED weighs 4.4 lb.

 

My SV70T triplet weighs 4.4 lb.

 

An Orion ED80 (which is an 80, not a 70) weighs 5.7 lb.

 

Your Televue Pronto weighs 6 lb.

 

A quick search found a carbon-fiber-tubed TS Optics ED 70mm from APM:

...which weighs 3.7 lb... but I'm thinking that it's going to be pretty hard to find a decent 70mm ED scope that's much lighter than that.

 

Still... a savings of eleven ounces (or more) over the other options, may be enough to make it manageable for your relative.

Don’t forget our sponsor’s AT72ED II, which weighs 4.8 lbs.

I am going to get the TS carbon fibre 70mm. It seems most ideal from a low weight PoV, and also look for a CF tripod and mount suitable for mags up to 75x (say).
