I have an opportunity to pick up a used Televue 76 at a very good price. I have always been a one-scope sort of guy, but the TV 76 is a very attractive travel and grab-N-go scope to compliment my "much" larger TV 102. I would use it when travelling to dark skies (the cottage, camping, etc), or in the winter when setting up the 102 and Great Polaris mount is too much to bear. I have a Gibraltar head and some aluminium tripod legs that would be used to mount the scope.

My concerns: 1) would I use my TV 102 less due to the convenience of this little guy, and in so doing I would miss out on the deeper grasp of the larger scope? 2) do I really need a second scope, and will the views be disappointing compared to the 102 so that I don't use the 76 enough?

There are several people here who have similar scopes in their collection, and many of them seem to favour the smaller one. I would appreciate any thoughts/experiences they may have.

Can't you just get an alt az mount for the 4"? If I were adding to your collection I would be looking at adding aperture not subtracting.

Sounds like you already know how you'd use it, so if it's a good price you could sell it again for, why not? I would think a small scope could be handy for various reasons, some of which you've named.

The 102 itself is actually too big for me to travel with once we pack the car with all of the kid's stuff :) Loaded in it's case will all eyepieces and accessories it is not all that small, it occupies half our trunk space with the tripod and mount.

I do have an alt/az mount for it (the same Gibraltar).

I have chased aperture in the past, but sold my larger scope (a 7" Mak) in favour of the 4" refractor. I'm not going back there, at least until we retire to a dark-sky location where a big dob will be worthwhile.

I have a TV101 and for me, just for a travel scope, I might at some point get an Orion ST80 I could use on my camera tripod. Apparently there are differences between the TV76 and Ranger- I'm not sure if one or the other is more desirable.

I have more than one scope... :)

My two favorite refractors are my NP-101 and a William Optics 80mm F/7 FD, similar to the choice that faces you but the not quite as extreme.

I think it makes good sense to get the TV-76, it's a nice, compact scope that's a great performer. It's good for birding and terrestrial viewing, the 102 is too clumsy for such endeavors, it's also much handier for travel.

From a guy who owns 3", 4" and 5" refractors - I say buy it.

A small scope like the TV76 will complement your TV102 instead of competing with it.

You will eventually want a separate mount for each.

Oopps... Sorry.
Don't buy another telescope.
You may find you go out twice as often.

The Ranger and the Pronto were 70mm F/6.9 refractors, the name tag on the side says ED but apparently it's FK-5 which basically provides the same level of color correction as a crown-flint achromat. The Pronto was the original "little scope that could", a 70mm with a 2 inch focuser. I had one, great scope but the chromatic aberration bugaboo would raise it's head at opportune moments.

The Ranger used the same optics but had a 1.25 inch Helical focuser, more compact than the Pronto. Both are quite good optical, just not apos.

The TV-76 is essentially a Pronto with 76mm ED/apo objective.

Don't buy it . I was reading a post below that even the best refractors suffer astigmistism just from body heat radiating to the eyepiece. Just let me know if there is anything else I can talk you out of buying.

My 71fl would image around 300mm while my 125sd would image at 500mm. Trust me, you need both scopes.

TV102 + TV76 = more quality time under the stars :)

Buy it and enjoy :jump:

Since I got the 102 I just use the 76 even more.

You guys all failed miserably, I made an offer on the TV 76 :)

We'll see if I get it, my fate is not my own now....

If owning it becomes too problematic, I can help solve that problem... ;)

I forgot to mention the one big reason not to buy the TV-76:

I have an NP101 and a TV76 (and an 8" dob), and I say buy it. You won't regret it. When I'm at home I mostly use my NP101, but the TV76 is absolutely perfect for traveling. They serve complimentary purposes, and if you have the means it's wonderful having options. Best of luck!

No question buy the TV 76, the scope's wide field ability will compliment the TV 102 and provide you with a great travel scope.

Well, the TV-76 is too close to a 400MM Lens if you are into photography, making it redundant. Get the TV-85 instead.

Oh well, you already bought the TV-76. A good traveling hardcase for it is the Pelican 1510. With the divider and cargo net for the top lid you can pack the scope with rings and diagonal attached, a few EPs, and room for 3 days of clothes.

Good choice in scopes. I have both the 76 and 102 as well.

I didn't get the TV 76. No response from the seller to my offer, and the ad has been pulled.

Well, I'm $700 richer now, and my mind is more clearly made up that I need a travel scope. Yes, I need one.

Thanks everyone for your feedback.
