Srsly, 80 mm isn't going to get you much deep sky visually but as a camera lens the 80mm aperture is wonderful.
I have an 80 mm Fluorite doublet that cost under $1000 and shows no false colour in photos up to 5 minutes or more.... You don't have to spend the big bucks....

thanks... Explore Scientific has a 102 carbon fiber that weighs 7 lbs for 1499... I was originally considering an 8" EdgeHD for dso observing but at 14 lbs it requires a tripod that weights at least 40 w/counterweight. So perhaps this is a more viable solution

Hi, Neil. Welcome to CN. Who's that guy with you?

If the experiment goes well, see if the Adorama guys can show you this:
The thing to keep in mind is something like this next one shows a nice image, but again, it is bigger, and more expenive:

Planetary - you will need a short f/l EP to bump up the mags.

However the (carbon fibre) OTA only weighs 5.7lb. I reckon thatmust set some sort of record

I would like the 2nd one from the left please, thank you.
That looks like the William Optics version of the ubiquitous carbon fiber 80mm triplet. If you want something like that, Orion has a nice one available:

FWIW, I owned the Astro-Tech model and it was a great scope! I used it on the Celestron NexStar mount. Very lightweight and very portable.

Here it is at zenith

Can you use the scope just in manual mode? I like to just point it at something sometimes.
