Looking around, I don't see any 80mm refractors in the f/6 to f/8 range other than ED versions that are out of my budget. It also appears that most in this class are on EQ rather than Alt/Az mounts.
That is the unfortunate truth, it would be great if someone made an ST-80 type scope that was F/6 or F/7. If you are looking for ST-80 robustness, I don't know of anything out there though I hear rumors that Antares makes something.
An old style 80mm F/11 or a 90mm F/10 has some virtues but generally today's mounts are on the flimsy side...

Yeah. I'm concerned with the poor mounts that accompany most of the less expensive slow refractors. Some of these scopes are really not too bad, but are very frustrating to the uninitiated.
I noticed Vixen offers an 80mm f/11 on their PortaMount.

I'm wondering if a 6" or 8" dob is a better bet.
That or one of the 130mm reflectors on an EQ. The EQ seems a little dicey for the newbie though.

I don't know anything about the SkyScout, but it might help with the complete novice family
My version of that is the Orion Smartphone holder ($32) mounted to the rear scope ring via a mini ball head ($12). Pop your smartphone or iPod in, fire up skysafari, point the scope at a known object, center that object in skysafari, and hit the gyro button. From then on, skysafari can tell you where to point the scope, and/or what you are pointing at.

I don't think so, because you are going to show them how to use it. That is VERY different than reading through the manual...I'm a noob and figured it out on my own from the Orion manual (which is very well-written I must admit).
What's frustrating to me is keeping things in the FOV, but the EQ makes that a breeze even with a really basic, 2-minute eyeballed polar alignment. And I just added the RA motor ($70) so next time I go out even using the slow motion is a thing of the past.

I don't know what device you are using but so far, I have not seen evidence that the phones and tablets are accurate enough to put an object in the field of view of anything but a very widefield scope. Maybe yours is better.
As far as equatorial mounts go... in a situation like this, simplicity is the key and there are several gotchas with an EQ mount.

SkySafari3 on the iPhone4 in gyro mode (i.e. not using the compass) is good to about 3*.

I think if you stretch your budget a smidgeon, a Televue NP101 with a Meade LX 80 would provide someone with years of enjoyment. (Just add a 0.........).
My real vote is either the ST80 on a vixen mini porta mount (and I like the erect image diagonal with an inexpensive zoom), perhaps have it include a cheap red dot finder and a cheap barlow, or, a GSO 8"dob package. (The dob would certainly catch bidders eyes.......)

Too bad you can't buy both a dob and a short refractor and report back to us which one works out better

With a Alt-Alz mount tripod could make a nice grab and go for someone not wanting a full size dob.
Thanks Tony
A tripod capable of handling a 6 inch F/5 Starblast represents a significant investment and in the end will require more effort to setup than a full sized Dob.

I see what you mean Jon
It's larger than I thought. I was thinking not much bigger than my sky scanner until I actually look at the specs.
Anyway hope your auction goes well. I see many kids interested when they come to our astronomy club . It's a great idea for an auction

Among my collection of telescopes and mounts, I happen to have an iOptron R-80 Optical Tube Assembly. It has the poorest plastic focuser I have ever seen, worse than a $40 department scope. I replaced it with the focuser from an ST-80, the mount may be good but the scope itself is a deal killer.
