Model: startravel-80-10734Part Number: 10734
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.
Optically this telescope is better than its price suggests!
“The lowest power eyepiece (25mm) provided a x16 magnification, which gave an estimated field of view of 2.5 degrees. Stars remained sharp across 75% of the view. With this eyepiece, widefield views were particularly good; open cluster M44 was a delight. These wide views did seem to make the background sky lighter, but we could still make out the brighter Messier objects and even spotted the galaxy NGC 2903 in Leo. At higher magnifications the galaxy group of M65/M66 and NGC 3628 could be seen, and by adding the Barlow lens to the 10mm eyepiece we split Algieba and Castor… Saturn was also clear, with Titan and Rhea visible. Overall score 87%”BBC Sky At Night Magazine
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!
Observers review:As a pick up and go observers scope it makes for a light weight travel option, it has fast optics and short tube length which means you will get lots of false colour on bright edges you will also get some colour distortion but the views per £ certainly outweigh any negatives. Some of these issues can be resolved with filters you may want anyway. Great starter scope and much MUCH! better than these national geographic type starter scopes on fleabay and supermarket clearance shelves, in fact itís not in that league at all. Imagers review: Well what good can be said about the Startravel 80 OTA? Well from an imagerís point of view a lot! This little gem finds its way atop of some of the worldís most exotic telescopes, the reason is because at f/5 it has fast optics which means for astro imaging it makes a great guide scope, easily picking out faint stars, when youíre in a bleak area of little guide stars to choose near the target a fast scope is a bonus, otherwise youíre going to need a way of moving the guide scope about, this will introduce flexure a long exposure imagers nightmare, I have only once ever needed to move the ST80 to find a guide star, I simply loosened the front scope ring and wedged a small piece of firm paper between the scope ring and the ST80 tube, this raised the scope enough to find a guide star. ST80 remains rigidly bolted above the imaging scope. I hate guide scope rings, thank fully I donít need them.
