I see that the OP got the TAK FC 76, which is an excellent choice, so this is a bit moot. However, if anyone else wants a small, high-quality travel scope, you might consider that Stellarvue has its 80mm triplet with carbon fiber tube for $1795. Some people do not like carbon fiber, but it does make for a lighter tube. I have had the SV carbon fiber 80mm apo triplet for several years, and have found it to be a highly versatile, easily transportable, and optically splendid instrument. I wish I had had it ten years ago when I got a chance to go to Lake Titicaca and view the southern skies from 12,000 feet. With a high-quality zoom eyepiece, like the TV 3-6mm, you can even get pleasing high magnification views.

Isn't the Tak lighter than most 80mm triplets today?  I had an FS76, it was pretty light as they go.

The FC76d ota weighs in at just over 6 lbs. With rings and dovetail plate attached mine is 8.5 lbs. Add a 2" ep and I'm looking at about 9 lbs on the mount.

Ok folks, I'd like to pick your brains about small aperture APO scopes.
As my b-day is coming up this May I have been given the go-ahead to purchase a small, travel-sized APO.
I've checked out higher-end spotters from Zeiss, Swarovski, Leica, etc, but can't justify the high cost for a day scope with limited use for astro.
I'd like a scope that will do double-duty in both daytime spotting and astro use.
I am excited to finally be able to add some really nice glass to the stable.
Ya, it's apples to oranges here, but I know you folks have opinions on some of these, both good and bad. Not looking for any particular brand name or anything like that; looking for a real "keeper".

 

My candidates (so far):
Takahashi FC-76DS
William Optics APO’s (several)
Tele Vue TV76
Sky-Watcher Esprit 80 mm Triplet
Orion 80 mm ED F/6 CF Triplet
Meade 80 mm Series 6000 f/6
Astro Tech 72 ED ll

 

In a nutshell:
True APO optics
Small physical size
Mostly visual use, no AP.
70mm to 80mm
Up to $2500

Prefer larger, 2.5" dual-speed focusers
Also interested in classic scopes that may meet these requirements.

I am very satisfied with an AT72ED2 with a Baader 2” AMICI prism that I have been using for astronomy and spotting for a few years. It’s about 12” long, so travels well. With a 27 Pan it gives a 4 degree field at 16x.  4 degrees is the same FOV as the Telrad used on my Dob. Previously used a TV60 in this role, which is more compact, but like the AT72ED2 better.
 

Astro scopes used for spotting are more susceptible to damage than a spotting scope, and any scope that’s used for travel is susceptible to damage, loss, and theft, so I wouldn’t use a more expensive astro scope for these purposes. As a practical matter, don’t think using a more expensive scope in this role would have any advantage for me. I know the A-P Stowaway that I also own doesn’t although it’s a better astro scope.
