Celestron C6-N: A good-quality 6" Telescope for just £99!
Saturday, 18 July 2015 | Des
I've just bought this telescope OTA at the amazing clearance price of £99.
It's very lightweight, but of robust construction.
The telescope is supplied complete with a 6x30 Finder which provides a clear, bright image at night, plus a 20mm Plossl eyepiece (I haven't used this, so can't comment on its quality).
After collimating the primary and secondary mirrors, I found the optics to be remarkably good. The fast focal ratio of f5 gives lovely wide-field views, with crisp star images across almost the entire field of view, although with some softening at the very edge (as you might expect with such a fast focal ratio).
The rack & pinion focuser looks very basic, but functions well. It accepts only 1.25" eyepieces, but with a moderate focal length of 750mm, satisfyingly wide views are available using a basic 25/32mm Plossl, or 8-24mm zoom eyepiece. I therefore don't feel I'm missing out by not being able to use my 2" eyepieces.
On the first night's use, with less-than-ideal seeing conditions, the telescope gave me lovely views of the Double Cluster. With a 6mm William Optics SPL eyepiece, Saturn was well-defined. Albireo showed a beautiful blue-and-gold colour contrast. The Double Double in Lyra showed a reasonably good split of all four component stars.
Although the C6-N can't beat my CPC 800 Schmidt Cassegrain, or my 5" triplet refractor, at the price I paid it's absolutely unbeatable in terms of value for money and complements my other telescopes very well.
