Reviews

  Excellent Service from Harrison Telescopes  I had done some research before deciding on the Sky Watcher P150i but the next task was finding a trusted retailer. Going with a specialist quickly proved to be the right decision. Super fast delivery through a proper, premium courier and all questions answered promptly by email. Top service!  (25/08/2025) Christopher Latham - Northwich, Cheshire

  Excellent product and service  I ordered this telescope as an upgrade to my old Meade 70mm refractor and I am very pleased with the quality. The service from Harrisons was excellent as they dealt with a minor issue straight away without any problems. I will definitely be buying from them again.  (09/09/2024) Paul - West Lothian

  Great purchase   Bought to help get my son into astronomy and what a scope for the money. Harrison are really helpful, delivered fast and was the cheapest I could find. Will definitely buy from these guys again  (15/10/2023) Mark - Rotherham

  Great beginner's telescope  This telescope was easy to set up and connected to my iPhone over its own WiFi without a hitch and was then able to use the built-in alignment function and use the app to find and automatically point at objects in the night sky. Just need some clearer nights to get out and enjoy it more now!  (28/01/2022) Neil - Cheshire

  Can't wait till the rain storm   The Telescope arrived and was so easy to set but have not been able to use it yet. Having made my own 6in reflector 35 years ago but was unable to make a standard had to use a workmate. This ket is perfect for me.  (08/08/2021) Chris - Kingston Bagpuize

  Between the clouds it’s fab (as are Harrison’s)  Sod’s law - no clear nights some this arrived very quickly, well packaged and easy to set up. Between the clouds the moon & random stars have looked awesome. The app seems brill, but needs more testing.

  Outstanding value  This scope is a must for beginner and veteran observer. Been observing for around 40 years now and I am enjoying using this scope very much indeed. Very easy to set up and a joy to use. Can think of no negative aspects as it does 'what it says on the tin' very well indeed. Roll on winter nights!   (30/08/2019) Ian K - Paisley

  Great Service and a Great Telescope  quick & helpful advice from Ed at Harrison Telescopes. I've only been using the scope for a week or so, but setup is straightforward and the Go-To capability is so useful.   (31/12/2018) Andy - Bexleyheath

  Firts serious telescope  I bought this as my first serious telescope. I was delighted with the service and the speedy delivery I received. I found the set up to be really easy and I was star spotting in no time. I’m now looking for more clear nights in which to explore the night sky. Thanks for the exeptional service.   (20/08/2018) Paul Thomas - Newcastle upon Tyne

  Excellent   Purchased in November last year, has really helped me locate objects, each object has been bang on target and tracks very well. Its also a very light version of the 150p aperture telescopes, so very easy to carry around! As usual excellent service and v fast delivery from Harrisons!   (22/01/2018) Simon - Biggin Hill

  First proper telescope   Received the telescope amazingly fast and well packed. Opened the boxes to check everything was there and intact. Got my son to check it all out he said it works great and even only looking at a twilight moon the image was lovely. It's be reboxed as it's hubby's Christmas present but he'll be happy.   (01/12/2017) Mrs Hilary Austin - Bognor Regis

  Fast Delivery  The delivery was fast and on time. The telescope unfortunately i couldn`t test it so much do to weather conditions. Good Communication with the seller.   (27/11/2017) Angelica - London

  Outstanding All Round Scope   Continued - I would also like to say the service I received from Ed to source me one of these was impeccable. Great communication and information and fast delivery. Will definitely be using using you for other products many thanks.   (27/05/2017) Gary Yule - Stretford, Manchester

  Outstanding All Round Scope  Upgraded to one of these from a 130 on a EQ2 Mount. The difference is out of this world (excuse the punn) At first light after a extremely easy alignment process I managed to see Jupiter's cloud bands red spot and all four moons, The dumbell nebula and whirlpool galaxy. Really is a excellent scope   (27/05/2017) Gary Yule - Stretford, Manchester

  First proper telescope  I took up Astronomy very recently using Celestron binoculars. Got the bug & decided to take the plunge to get a beginners reflector telescope. I have not regretted it. A very good scope for the price; extremely pleased with it and the extra plossls/filters I added. Good service from Harrisons.   (07/04/2017) Tim - Herts

  My first big telescope  I had a 60mm telescope but wanted goto and tracking. This 150 allows me to see much more and the tracking is much better than "nudging". If you want a big telescope with the find and track this is perfect. The setup took a bit of practice but I am very happy with this choice.   (11/12/2015) Robert Parsons - Brighton Sussex
