Radial Guider manual question

I purchased a Celestron Radial guider but found no manual in the box. I was told by the dealer that it is not required as the guider is very simple to use. Is there anyone who purchased this item and can tell me if manual is supplied or not?

Thanks,
Levente

No real "manual" per se, but there was a one page "flyer" in the box as far as I can remember (been a few years since owning). I'm sure Celestron would mail, FAX, or email a pdf file (Have you checked the Celestron site BTW?) for free.

On the other hand the dealer is kind of right - it's a pretty straight forward item to use. What questions do you have??

I read and printed the doc mentioned in this forum and noticed it speaking of a "Drive Corrector". Can any of you explain what a drive corrector is, and is it really neccessary for astrophotography?
