Over the years I've had, and sadly sold off, the scopes below:
Tele Vue 85, that spoiled me for false color. Small compact package. weighs some, and if you are going 2" the diagonal and eyepieces add to the weight. Very early version
More than a few of the common but still excellent Vixen 80mm f/11 achromat, lightweight, but longer than the TV-85. Vintage, Japan, branded Celestron or Vixen
The uncommon Vixen 90 f/11-ish achromat, made in Japan pre-2000
Vixen/Celestron 90mm fluorite, mid 1990's
Vixen 102mm fluorite, circa 2000, Orion by Vixen
One of my pet peeves are website/internet/forum post headlines:
"What is the best..."
Change "best" to "appropriate" and consider also "trade offs."
Things to consider:
The above differ in size & weight. Some are better grab and go than others.
I have not had an apo that is lighter than the TV-85; wish I had.
Price range is large. And higher price scopes somehow seem to demand pricey accessories!
I'm not anthropomorphizing too much, but my TV-85 would pout if I used an "economy" eyepiece in it.
The above all have acceptable to excellent optical quality; some are better at wide field than others and some are limited in wide field. I doubt I could be happy with a classic Short Tube 80, due to false color.
The difference between the Vixen 80 and 90 mm achromats visually was just enough better, and even closer to a 4" f/10-12 achromat that I would choose the 90mm over the 80mm. The 90mm is just that much smaller than a 4" to make difference. That makes the 80mm Vixen achromat in my mind less desirable. The problem is that Vixen 90mm achromats rarely show up for sale, have been priced high enough to make me consult the I Ching for advice, and then are sold quickly.
The other scopes differ more such such that each one occupies a slighty different spot.
The Vixen 90mm fluorite is even rarer.
But these days are a few 90mm apo class scopes, if that fits your want.
So, should you get an 80mm class scope to compliment other scopes?
I would say yes, but think about how you would use it to choose one to fit that use.
Do you want ultimate grab and go, wide field, does false color or expense make a difference?
