It sounded as if the seeing wasn't very good and that it was coming and going quite a bit. It is difficult to get good comparison results when the seeing isn't very good and is changing rapidly.
Maybe that particular Stowaway had a problem but the results of the review don't fit my experience. I've looked through several TV-85s they are very nice, but I also know that my f/7 Stowaway gives outstanding views.
My scopes are not safe queens they get out under the night sky. Here are some of the small refractors I currently own.
Celestron SS55F f/8 fluorite doublet
TV-76 ED doublet
Takahashi FS-78 fluorite doublet
Unbranded 90mm f/5.5 ED doublet
AP Stowaway 92mm f/5 fluorite triplet
AP Stowaway 92mm f/7 ED triplet

I recommend a Stellarvue SV85S. I own one and am always amazed at how well it performs for a doublet. It can certainly hold its own against some of the newer triplets that I have viewed through. I prefer to use it on an AltAz mount for portability reasons. I just ordered a Desert Sky Astro Mount for a grab and go. The views through this scope with a 22mm Nagler T4 are breathtaking!
In fact there is one for sale on A-mart:

Thanks, Rich.
That's a great collection of small scopes. Of those, the one that I would save from a burning building is the FS-78! I love doublets--especially small ones--since they cool so fast, and always being ready for action is part of what small scopes are about.

Hey Rich.
Where did ya get that from? 
Is it the black tube scope from Long Perng?
I've seen it on the Andrews (Australia) website, but not over here.

I'll chip in with the William Optics 10th Aniversary Edition. It has TMB designed optics, you can use a bino viewer without the oca. It looks great and performs great.

Hi Clive,
It is black and has a two speed focuser. I'll take a picture of it. I bought it at our astronomy club's annual auction and swap meet.

Okay Darren. Here's mine and yes, like yours, it really is a great little 80mm.

Edwin, you need to get a Starbeam!
Ok Starlighter! You do not have to throw it to me in face! I know my former and PROVISIONAL adjustment was unfortunate. But right now I do have a nice Stellarvue base for TV clamshells with my RDF... And it just looks very nice.
And Mike... I do have a laser finder. It`s nice, but it faults miserably in cold nights.

Your statement and the Bill one are right. But, IMHO, that only demonstrates the fact that the TV85 is so good that to compare it to very high-end triplets, larger in aperture, even must be made in carefully controlled conditions. It is easy to forget that the TV85 is only a doublet…

Yet you speak the truth. When I got my NP-101 and compared it with the 85, I soon discovered the smaller scope matched up pretty well. Yes, it does show some CA when a bright star is highly magnified, but for the most part, I don't see any CA to speak of. None with the moon. Mostly it's dimmer than the 101. It still resolves images with the best of them.

The star test looks very nice. An amazing ED doublet.
