Skywatcher Startravel 80 OTA
Specification and optics are the same as the Startravel-80 (ST80) but comes with 45º Erect Image Diagonal and is supplied without equatorial mount and tripod. Complete with tube rings and photo-tripod adapter.
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 Tian and Rhea visible. Overall score 87%”BBC Sky At Night Magazine
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.
