Where can i buy telescope lenses in the UK? Or internet?

Question

I have a Celestron Newtonian Refractor, and i need to buy some lenses for it, the lenses that came with it were not only kind of poor quality, (the best resolution i ever had of jupiter, was enough to see the planet and moons, but when i tried to see more, the best i could get was a dak blurry image with terrible colour) and since moving house i believe the lenses i had anyway have been misplaced...

Far and away the best eyepieces on the market are made by Televue. Here is a link to their website, which lists several dealers in the U.K. I would start there.

While you may need new eyepieces, I doubt that the problem you were experiencing was due to the eyepiece. Instead, I suspect:

1. You may have been seeing Jupiter when it was low in a humid, polluted, thermally unstable, or dusty sky. This will always result in poor views.

2. Your scope may not be collimated properly. If it is a Newtonian reflector and you are not familiar with the collimation process, then you will struggle with poor views until you learn how to do it. The following link describes the process. It looks complicated, but once you learn to do it, it takes a few minutes.

Most amateur astronomers using Newtonians have to collimate their scope on every outing to get good performance. I would try this before laying out big bucks for eyepieces (although good eyepieces are also excellent ways to improve your views).

Good Luck and Clear Skies!

Answer 2

if you call them "eyepieces", like everybody else does, ppl may have a better idea what you are talking about.

have a look at the ads in the magazines. try the sky at night, which will be more relevant to you in the u.k.

there is no such thing as a "newtonian refractor", btw.

Check the internet-- many retailers sell there--

Answer 4

It would actually help to hear what model telescope you have.  If we knew the focal length of the scope and the aperture, then we could suggest eyepiece focal lengths that may be of value.

I view Jupiter at 240x most of the time.  But my 254mm reflector can handle that and more.  It would be pointless on a 60mm scope, however.

Dark and blurry suggests you're using too high power for the scope.  Try lower power.

Answer 6

Pick up a copy of an astronomy magazine at your newsagent; it will contain ads from all the British telescope stores. Make sure what kind of telescope you have: there's no such thing as a Newtonian refractor. If you have a Newtonian reflector, follow the instructions which came with it to align the optics correctly; otherwise no eyepiece can help.
