About this product

Model:  st102ota

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 45-degree erect-image diagonal or as a ‘fast’ fixed aperture lens for both astrophotography and terrestrial photography (camera adapters available separately).

Great beginner scope
06 October 2022  | 

Almost completely new to astronomy (did have a very basic scope as a kid). Have to say, so far based on one evening of playing around the 102T exceeds my expectations. Very solidly built, and views of brighter objects (moon etc) show much less chromatic aberation than I was expecting from other comments about lower end APO refractors. I'm still in the learning process of getting the mount properly aligned, and everything dialled in - but am very happy with this as a starting off scope. Excellent for the low price. Delivery and service were great too.

My son declared he wanted a telescope for Christmas !! After making a horrendous purchase choice last November (Celestron Powerseeker 127, mainly due to lack of stock) my conscience was so great I felt obliged to right a wrong & this time decided to research, that, with seeing what was available within a specific budget decided upon the SW 102r OTA. Glad I did? Yes, well, first of all, FLO as per usual delivered within 36 hours (thumbs up there), secondly, my thinking was nothing could be worse than the previous purchase. The SW 102r OTA has surpassed all my expectations and more. After hearing horror stories of CA, it is there but expected worse on bright objects & can be taken out of images with Photoshop. It's very portable, fully operational within 1 minute & even on a crappy EQ1 mount any wobble has gone well within 3 seconds, also it is more stable in windy conditions. As usual the supplied eyepieces have a lot to be desired but saying that, the 25mm is most usable but upgrades vastly improve matters, also, will be upgrading the diagonal to a 90deg. dielectric. Focuser is not the worst I have experienced nor as bad as some reports, but not the best. Swapped out the supplied RDF to one purchased earlier, (supplied one felt sloppy). On the only clear sky (partial) in the past week, views & images of the Moon have been a joy, although smaller than through the reflector we now have sharp detail (to have any detail is a novelty), stars are pinpoint. Not had a chance to target DSO's yet due to cloud cover but I am ever hopeful. In all, this item is well worth the price & have no regrets making this purchase. Good job all round. Remember, Space is Deep.

My step up from an ST80
20 March 2022  | 

I'm very pleased with this economical refractor. Weight and size wise it perfectly suits my Az GTI mount. Despite a washed out sky last night due to the moon and local light pollution I was able to get very clear crisp views of the Pleiades and other objects. I have upgraded the focuser with a Skywatcher auto focuser which I had lying around and it makes a great difference. Having said that the original focuser was better than I had expected.
Once again excellent service from FLO, delivery was very quick.

A great compact telescope
06 March 2022  | 

I am so pleased that I decided to get this instrument. I use it on a Sky-Watcher Star Discovery WiFi AZ Go-To Astronomy Mount & Tripod; the results after a couple of sessions of use are great.
Visually the view of M42 in Orion is excellent, and I was just amazed when I saw the display on the back of my DSLR camera after taking the very first image of M42 with a 20 second exposure. I look forward to a lot of fun with this instrument in the future.
Great service as always from FLO, the review is only posted now that I have had the chance to get the telescope to somewhere with a reasonably dark sky.

Startravel 102 OTA review
31 January 2021  | 

I was impressed and surprised by how quickly FLO were able to supply me with this product under the circumstances - superb service as always.

I was able to test this scope on an almost full moon this week and in summary Im delighted by the performance overall.

I used the OTA with an EQ1 mount and tested with a range of eyepieces - including a 25mm Plossl with and without a 2x Barlow, and a Synta 8-24mm zoom. A moon filter was used to control brightness. In all cases the clarity of the optics was apparent - crystal clear images that are all the more impressive considering the price of this product. The Tycho crater was ultra sharp and a host of other clear lunar detail was in abundance. Id expected considerably more chromatic aberration bring an achromat, but there was really only very minor violet fringe evident - excellent performance and a great price. Highly recommended.

Fantastic refractor scope for a beginner like myself. Nice crisp contrasty views. A little bit of CA but knew that would be the case as it's on the cheaper end of the refractor scale. nice starter scope and extremely quick dispatch and delivery from FLO.

APO perfomence.
26 June 2020  | 

I have to say. For the price, this telescope looks like an Apo. There is no false colour visible which is, astonishing for telescope an F5 achromat. I tested it on some distant trees and I couldn't see any purple chromatic aberration.

The Sky-Watcher Startravel 102 has a focal length of 500mm F5 Doublet air-spaced Achromatic Refractor. This makes for a fast wide-field telescope good enough to show the user- the bright planets and messier objects, together with the brighter objects from the NGC catalogue and double stars.

The focuser is very good and feels solid. This was a nice surprise as I would have expected it to be low quality. SkyWatcher hasn't skimped on the build quality of the focuser. This telescope feels like an Apo- at half the price.

This evening I used the ST 102 for Lunar observation.

The Moon looked clear and sharp despite sharing the sky with some high altitude cirrus.

At F5 the Moon lacks contrast in bright daylight but it was clear with no false colour visible around the limb. If you use the dust cap with the centre dust cover removed. The focal length increases to F10. In this configuration, the Moon is more defined and shows more contrast. This configuration would be ideal for Lunar study-Planetary and Double star observation.

As I was using my IOptron Minitower II I aligned on the Moon. I decided to test the Startravel 102 telescope on some bright stars.
The Sun was very low on my horizon, and the skies were clear and still very bright. Using a 24mm eyepiece (Televue Panoptic) I selected Vega from the list of bright stars the handset had to offer and the mount and telescope turned towards Vega. I looked into the eyepiece and could see a very clear and very sharp tiny dot. There was no astigmatism or pinched optics or any sign of noticeable false colour. The optics are very well corrected.
Moving on I also saw Sadr followed by Arcturus and finally Deneb.

In my opinion, this 4-inch Achromat would be a good choice for anyone wishing to move on from Binoculars to have as there first telescope for any budding amateur astronomer. It is a very good compromise for any person who has a tight budget, and who can't afford an apo. The tube is very light and made from a single sheet of Aluminium. It is finished in Sky-Watchers now-famous Black Diamond paint with Pearl - White dew shield and Focuser.

Achromatic Refractors have certainly come a long way.

First light

Thanks FLO for great service again.
For its price point this is a great scope and will help any budding astronomer get into the hobby and give plenty of sleepless nights.
It is well made and even the standard focuser works very well, also reasonably light, portable and fast.
I didn't buy this for normal astronomy or terrestrial viewing so cannot comment on how good it is from that side - check other reviews.
Attach a daystar quark, mono camera, put 82mm ERF at the front with FLO's blacker than the blackest black stuff (flocking) in the middle and you are looking at a scope that out performs my Equinox 80 and WO71. As I use the Quark Prominence it even out performs my old Coronodo Solar Max ii for Prominence's. WARNING - DO NOT make these adjustments unless you are totally sure of what you are doing - eye damage will result I am an experienced solar imager.
.FANTASTIC for solar with adaptations made and no need to change the focuser.

Stay safe and clear skies
