  1. Hello everyone I've just bought my first telescope, a 10 inch Dobsonian, Saxon brand (same as Skywatcher). In daylight I've collimated it with a laser collimator. Also in delight I've centred the finderscope on a house on the horizon (probably 5 km away). The image is inverted and the left side appears on the right. I understand that's normal. The house is also centred in the eyepiece and the view is inverted and left appears right, as with the finder scope. BUT the horizon is at about a 60 degree angle ( see pdf sketch attached). Is this normal? Or am I doing something wrong? Or is there a problem with the telescope? Many thanks in advance Susan telescope views25082020_2.pdf
  2. SkyWatcher Skyliner 250 PX 10" Dobsonian Telescope. This telescope needs a new home as I have used it very little, having become more interested in astrophotography rather than observing. In good condition with base modified with lazy Susan bearing, angle scale with pointer and bubble level, Machine-Dro digital RA angle gauge (needs new battery) to complement the scale on the base. Also included is a sturdy plywood base with adjustable feet to stand the telescope on so it can be leveled easily. Two eyepieces are included...10mm and 25mm. No finderscope is included, but these are readily available. There are a couple of small smudges on the mirror (see photo) but I expect these will wash off easily and don't affect performance. Focus wheel rubber grips have split, but operation is not affected. Collection only due to size from Swindon or possibly Abingdon in office hours. £225 Thanks for looking.
  3. I have decided to sell 'Big Blue' my 22" computerised dobsonian telescope. I would like somebody to get the benefit from the scope, otherwise it will be sitting in storage indefinitely. Many people on the forum will know this scope well. This is a big telescope, built by Arthur Edwards, 22" mirror, F4.8. It comes with GOTO Servocat / Argo Navis. I have added locking castors to the base so it can be wheeled on a flat surface, I use long strips of plywood to move it easily. It has a shroud, mirror box, moonlite focuser, telrad, battery, bag for the poles, step ladders included. Will not split any of the parts. I will get some images up next week. Telescope is at Loch Rannoch, Perthshire, Scotland. £2500
