Adjusting the SkyWatcher Crayford Focuser

Since we're in the testing phase, I thought it might prove helpful to try a post with a couple of attachments in one of the sub-forums...

I have three Skywatcher telescopes (one 100mm & two 80mm). The SW focusers can be a little tricky to adjust, even to those accustomed to "regular" Crayford style focusers. I came across this piece when helping a friend in Florida a couple of years ago.

I have the entire article in PDF format, but can't attach it to the forum. If anyone needs it, please send a PM with your email address.

Okay! I had two files that I attached, but only one showed up above. I'll post it here...

It seems that the forum doesn't like two files placed in-line in the same thread. It's not a major issue, as one can simply make two separate posts (each with one pic).

I'm gonna try it one more time without trying to stack them myself, omitting a "Return" between the placement...

Bingo!

By just letting the forum place them in-line without any spaces or return, they will be stacked as we like 'em.

Not a big deal, but something to remember for the future. 8-)

Thank you for the write up John, hopefully the PDF upload is a minor fix to activate.

Thanks for uploading!
I have had this manual on my computer and used it two times.
Very useful!
So owners of this focusser: Download it!!
Sooner or later you'll be thankful to have done so!
Thanks Lowjiber and Gordon!

Thanks for the pdf,
I have recently bought an ED80 and was thinking that the focuser was a bit loose and feeling a little nervous about hanging a dslr from it.
I'll give this procedure a try!
