Specification and optics are the same as the Startravel-80 (ST80) but supplied without equatorial mount/tripod and includes a 45º Erect Image Diagonal.
Popular as a travel-scope, for grab-and-go astronomy and for use as a guidescope.

Excellent product and excellent service
A great telescope package for a budget price.

I have only just bought this Sky-Watcher Startravel 80 OTA a couple of weeks ago and only the last couple of nights, having been clear skies, have I had a chance to try it out.
On arrival, it was very easy to assemble and to align the finderscope. Attaching my own current dovetail was easy and straightforward. I found the telescope very easy to use.
I am really pleased with it and after attaching my DSLR with the aid of an extension sleeve, I am more than happy with the quality of the photos I was able to take.

My first purchase from FLO and it was first class service. I bought the ST80 as a guide scope for my SCT and am impressed with the value for money that this offers. I would have bought the guide scope pack that FLO offer, but the 1.25" extension tube seems to be unavailable. I decided to buy the ST80 and ASI120MM mini separate and see how much back focus was needed. What I discovered was that the supplied Barlow can be adapted by unscrewing the lens to give enough extension so the the ASI120MM mini can be used with its also supplied extension. It fits nice and rigidly and I'm pretty confident flexure will not be too much of an issue.
My scope was mounted to the SCT on a custom made bar. The rings can be removed from the mounting block and are taped M6. This keeps the profile lower and helps rigidity.

My first purchase that hasn't come with clouds. FLO is my new goto for astro kit.
Very good refractor with some limitations but absolutely great value for money

First of all let me congratulate FLO for solving a minor bureaucratic error with speed; it's five star service. This little scope serves the purpose that I bought it for admirably.
I was not expecting that the scope would give me perfect views of Jupiter and Saturn at high magnification and it cannot because of chromatic aberrations above 30x magnification or so. If you want to study the Planets and the Moon in detail then invest your money elsewhere and buy a scope with a much longer focal length which you can buy for a good price on this website.
I tested the the scope over three nights for visual observations. With a 15 mm eyepiece ( about 26x magnification) it was able to split the "Albireo double star" into its orange and blue components and it was a magnificent sight over 75% of the field of view. I was also able to sweep the Milky Way and see star fields and double stars unknown to me.
The next night with a 26mm eyepiece ( about 16x magnification) my wife and I had a spectacular view of Jupiter and its 4 galilean moons. These were visible over 75% of the FOV. I did not get good results with a 9.7 mm eyepiece owing to chromatic aberration.
The following night I observed Saturn with a 12.5 mm eyepiece and could see the rings but I couldn't see a gap between the rings and the planet. I used a reasonable quality Barlow 2x lens to give a magnification of 64X but I still could not observe a gap between the rings and the planet. Saturn was low in the sky and the street lights were blaring we also have appalling light pollution where we live. Under dark skies the scope will no doubt perform better.
In general I am well pleased with the scope.
Pros: Arrived well packed and perfectly collimated and aligned and easy to assemble, be sure to put the rubber grommet in the correct place on the finderscope,
Built very strongly of aluminium including finder scope. So strong that when I accidently dropped it, but not from a great height ; there was no damage and still collimated perfectly,
Good optically at low powers, ditch the 10mm supplied eyepiece and perhaps replace it with a better quality 12.5 mm or 15 mm eyepiece,
Easily portable to carry into the garden for a quick observation or for carrying to a dark skies site or on holiday,
Can be mounted on a sturdy tripod with either equatorial or alt-az mount or even a photographic tripod,
Ideal for beginners and star parties. It will be going to school astronomical nights when the lockdown ends,
A dslr camera can be attached easily . It can be used as a guide-scope for larger telescope to do semi-professional or experienced amateur astrophotography.
It can also be used as a spotting scope; mine came with a prism to erect the image, very good optical quality at 16X and 25X,
Exceptionally good value for money, it is better than I thought it would be and I am pleased with it, it will be used a lot for stargazing rather than planet and moon gazing.
Cons: Limited optical quality, the optical attributes can be improved by using better quality eyepieces or perhaps replacing the prism with a star diagonal mirror.
For 100 pounds you cannot really go wrong and it is ideal for a beginner or youngster.

A great little telescope that also works very well as a guide scope for astro imaging.

I have not yet tried it out seriously, but I think it will be great, it seems so

Build quality is perhaps average, but optics is excellent. The bundled accessoires was a welcome surprise, a nice 6x30 straight through finderscope and a decent 2x barlow. This telescope will be used a lot, mainly because it's so portabel. Sure 80mm aperture is limiting but I'm not picky, it's still better and/or more fun than a pair of binoculars. Thanks

I was initially dubious about the low cost of this telescope. How can something so cheap be any good?
Well I need not have worried. The telescope is outstanding as a guide scope which was bought for this purpose. The Lodeastar X2 has a long optical path and as I like to attach this to a C-adapter for rigidity (I don't like it inserted like an eyepiece) I was really pleased to find a standard T-Thread on the back of the ocular slot. I had to fit an additional T-ring to focus the Lodestar but this is not unexpected as I knew I was completely replacing the diagonal.
I am still surprised by the amount and quality of the accessories. Very good mounting rings, a finder scope, 2 reasonable quality eyepieces, a barlow & a diagonal. The quality of the image when focused on Jupiter would never set the world on fire but your getting a lot for little money. As a guide scope it is very good I use PHD or the SkyX & with the lodestar the 80mm objective pulls in a nice number of faint stars.
The rack & pinion focuser is not the world's best but it is quite precise eventhough the rotation on mine looks a little uneven- I'm not complaining as it will not be used much as its mainly a guidescope. It has a lock screw so it's not going to move.
The rings are really solid & felt lined (a nice touch) and I have mounted mine in a losmandy type slot using the custom adapter.
In summary I'm well pleased & consider I have got a great guidescope which is worth much more than the amount asked.

As a guide 'scope for imaging this little telescope is hard to beat. It's weakness for observing - chromatic aberration and poor UV filtering - is a positive benefit for guiding as a good guide camera like the Lodestar, together with PHD guide software, work best with very slightly diffused stars. So this telescope gets 5 for guide purposes - I don't use it for observing!
