Customer Reviews

  Excellent   My telescope arrived in excellent condition. Also the guys at Harrisons are extremely helpful, I havent even been able to use it yet since it has been so cloudy, but already I have phoned for help and been given very friendly support. Fingers crossed for clear skies! Thank you Harrisons :-)  (08/12/2017) Tracey - Surrey

  Excellent service  I bought this telescope as a thank-you to a staff member for all his hard work over the past few years. He is keen on anything to do with the cosmos and I thought this would be an ideal gift. The service I got from Harrisons was outstanding. Will review the telescope itself later.   (11/08/2017) Philip - Morland

  Celestron NexStar 127 SLT Telescope  This is a lovely compact piece of kit but not at the expense of viewing quality. I've Never been able truly master the manual equatorial mounts but the computerised mounts are certainly the way to go. I'm very pleased with it and got the best price from Harrison's. Great delivery too. Many thanks.   (23/06/2017) Rowan - Hookwood, Surrey, UK

  A Great Step-up 'Scope  Easy to assemble, carry (compact), align (with practice), aim and use (tracking is a boon). x240 no problem (Moon at least). Footpads with extra drilled recesses aid stability and visibility. A dewshield made from a piece of camping mat is a simple and useful accessory. Ready to go! Great results.   (17/12/2015) geministar - Merseyside
