I assume you did not get rings, which is a solvable problem.
I have a faint recollection that it has a tripod mount base attached to the tube, but I have no clue what your balance would be like, and using photo tripods can be disappointing.
It's been years since I sold mine, and I do remember complaints about not being able to find rings, however, I believe if you measure the tube diameter you'll be just slightly short of an easily accessible ring diameter that will work fine with felt padding. Agena or Orion, I think.
Wish I could remember the numbers, however, it's been years.
You'll have to be careful with your dovetail length, make sure you can balance the tube properly.
The sled focuser can be converted to a baader clicklock or some other upgraded visual back, as the threads in the sled focuser are the standard 36.4 mm Vixen threads, and adapters are available to take it up to T2.
I used mine on a T head zero friction alt-az. The tube is probably too long for the Vixen Porta style mounts, and too heavy for the Porta itself.
I used it on a long discontinued Williams eztouch, clone of a AYOSwiss, and a Sergio Bonilla.
I mount either on a surveyor's tripod with swapped center bolt (pitch matched).
Any properly sized GEM mount will work fine also.
I guess you could use it on a photo tripod, but I would look for a cg3 through cg5 size mount, at the very minimum. As always, buy as much mount as you can afford.
Eyepieces will entirely depend on your pocketbook and your expected use. My plossls are now used Televue, but I usually prefer wide fields, tons of choices. Always a great bang for the buck choice is the Baader Q Turret box set, with 3 orthos, a plossl, turret and 2-position Barlow for $250 at AgenaAstro.
They're great scopes, and the orange tubes are supposed to be better optically than the black tubes. my black tube was fine, but had some discoloration around the edges of the secondary that, fortunately, washed right off with a bit of soap and water with a distilled water rinse. Cleaning, of course, is never recommended, but the secondary was compromised.
Your maximum field in 1.25 will be with a 20 degree 82mm, but 18mm and 24 mm APM UFFs at 65-70 degrees should compliment the scope nicely.
