The Sky-Watcher Startravel 102 telescope is a tried & trusted two-element, air-spaced achromatic refractor that provides wonderful wide-field views of comets, star fields, star clusters, nebulae, bright galaxies & planets, the Moon and Sun (with proper safety filtering!).
It is also an excellent telescope for daytime terrestrial observing when used with the supplied erecting prism or as a ‘fast’ fixed aperture lense for both astrophotography and terrestrial photography (camera adapters available separately).
I love this little scope. I purchased it as an F5 RFT in its own right but also as a finderscope for a Vixen VMC200L. I replaced the diagonal with a 2" one which allows a full range of quality eyepieces to be used irrespective of exit pupil size or vignetting.It is a great little performer for just browsing stars and nebulae at low magnification and surprisingly tolerates a magnification of X80 with very little false color, rendering pleasing views of Saturn, Jupiter and tight objects such as M13 and theta orionis. The extra aperture over an 80mm certainly makes a significant difference in detecting faint objects.It is a robust bit of kit with no frills. It is so relatively inexpensive for the quality of the optics that I purchased another with a 50mm erect image diagonal as a balcony telescope for a gift with a Sywatcher 28mm LERFor the price, the coma and chromatic aberrations are not worth criticising if you use a good quality diagonal and eyepieces. Care needs to be taken in accessory choice due to limited infocus travel.For Astronomy I use this little scope as much as the larger Vixen and have also found that it makes a very good telescope for an auto-guider.
This scope is a solid build, and feels quality through and through. Very little plastic - the all metal rack & pinion focuser is silky smooth, with no focusing tube drift during focusing. The tube is finished in the "black diamond" metallic paint, and is a solid tube, not rolled sheet metal. The short tube and solid build give this scope the feel of an apo, though it is an achromat.In use, the telescope gave bright, sharp wide field images of the Orion Nebula, with plenty of intricate detail. The Crab Nebula was clearly visible, and stars showed no noticeable coma or CA. When used on the Moon at low magnifications, the scope gave razor sharp images with no noticeable CA. At higher powers CA was apparent but not troublesome.High magnification views of Jupiter showed CA as a blue/violet halo around the planet, which was not hugely distracting, and disappeared entirely with a yellow filter. Surface detail was exquisite, indicating excellent resolving power. The four Galilean moons were shown as clean pin-points of light.Overall; for the price, this is a whole lot of telescope, and is a good all-rounder for the generalist. For DSOs, the scope really comes into its own, and its supreme portability makes it the ideal grab and go for expeditions to dark sky sights.I have used the scope on a SkyWatcher Az SynScan mount, which handles it well, but is prone to wobble in all but the gentlest of breezes. Also, reaching Zenith with the scope on this mount may be a bit of a problem, but not a deal-breaker by any means.Excellent value for money.
