That's very interesting. Thanks for that.
Can you tell me if this one is a p model or not? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120607209343&ssPageName=STRK:MEWAX:IT

Hi,
Just a quick bit of advice...
The standard 114 has an additional lense built into the focusing tube in order to achieve a focal length of 1000mm. It also has a plain spherical mirror not often used anymore. I owned this scope once and found the optics are ok at low power, but when using a 10mm eyepiece at x100 and then the addtional supplied barlow for x200, the optics are not really up to scratch giving a blurred view of the moon and planets. And yes, it was collimated. I got rid of it.
Make sure you get the 114P model as this has a parabolic mirror and does not have the additional lense in the focuser. This results in a much sharper image. True, the focal length is half of what it was, but you can just get a good Barlow to get the higher mags if you are moon and planet watching. If you are deep sky watching the reduced focal length is an improvement as you get a much wider field of view.
Even better, the 130P has the same improvements but will give a brighter image due to the apeture increase.
My two shekels...
