Home Telescopes SkyWatcher Telescopes SkyWatcher Dobsonian Telescopes SkyWatcher Classic 250P Dobsonian Telescope
A superb value larger aperture telescope that offers the best and simplest solution to observe deep sky objects with, the 10 inch parabolic mirror will provide excellent views with minimal setup time. Smooth motions in both axis from the solidly constructed rocker box allow the use of higher magnifications for planetary observing, taking full advantage of the high resolution this instrument is capable of.These instruments offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the late 1970’s, is a very simple but effective method of mounting a Newtonian Reflector, based on the alt-azimuth principle. Fast and easy to set up, the Dobsonian mount consists of a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and to use frictional materials, which allow it to move easily when nudged but to stay in position when not. The mount is designed to be driven by hand as opposed to slow motion controls.Radiant Aluminum Quartz (RAQ) Mirror CoatingPrimary mirror and secondary mirror with Radiant Aluminum Quartz (RAQ) coating providing up to 94% reflectivity with optimal durability and long term performance.
Sky-Watcher Dobsonians feature a unique patented Tensioner/Carrying handle. By lifting the handles together, you can easily carry the whole unit in an upright position with the help of a friend.

Excellent service/delivery for gifted telescope (04/02/2024) -
Great service, Great Scope, need better weather. Firstly the ordering experience was superb, the delivery was excellent and the scope has already allowed me to get up close and personal with the moon; will do more when the weather improves. The build quality is excellent and the construction of the base was simplicity itself. Well done all of you. (05/05/2023) - South Coast UK
Great service, great telescope Telescope: I was recommended this as a beginner telescope and after collimating it I am really impressed, easy set up, good starter eyepieces - Great! Service: I contacted Harrison on a thursday with some questions, answered within an hour, had my telescope the next day, I got a great service. (02/05/2023) -
Excellent recommendation, great telescope The team at Harrison Telescopes suggested the dobsonian as excellent magnification but bulky. I found a way to manage the bulk and this telescope arrived the next day. Truly amazing views and and my best ever sunspot sighting. Great camera connector, very stable and smooth focus. Very pleased. (14/03/2022) -
Skywatcher I pwned the 6in version of this for 8yrs so I am now the proud owner of the 10in now, I am real happy with this scope and I hope to use my cannon dslr with it. In all I would recommend this to anyone, even the beginner as its so easy to use. John (28/06/2019) John - Falkirk
Great service Really nice product Speedy delivery and great looking kit. Easily assembled with clear instructions.Also happy with customer service over a couple of queries.The reason for 4* is the use of just three very small Teflon pads on the turn table requiring more than a nudge to turn the scope.Rollers or PTFE would be better.
