Just acquired both a Skywatcher 2" Low-Profile Crayford focuser and a Skywatcher Coma Corrector for my old-style blue Skywatcher 200P. Just a couple words of caution for anyone with one of these scopes.
Firstly, I originally intended just getting the Coma Corrector, but found that it couldn't come to focus with my DSLR using the stock Rack and Pinion focuser, even though the DSLR focussed OK without it.
So, Caution 1 is that even though the CC is intended for f/5 200mm Skywatchers, it doesn't necessarily work for all of them if they've got an old-style focuser.
Secondly, I therefore subsequently had to invest in a Skywatcher Low-Profile Crayford to enable the DSLR to focus. The instructions indicate (and some postings here confirm that some people have been lucky) that the four fixing bolts are in the same position as the original ones, so will fit the original tube without drilling new holes. Not so with mine! I had to drill new holes about 6mm either side of the original ones.
So, Caution 2 is that you may need to drill new holes even if the instructions indicate otherwise.
So I'm now more than a hundred quid lighter than I was expecting to be. Ouch! But that's par for the course with this game.
Anyway, I'm now the lucky owner of a georgeous shiny new Low-profile Crayford focuser and Coma Corrector. Hopefully a first light report to follow.
And many thanks to FLO again for their superb and speedy service. It's amazing to order something at lunchtime and receive it at 8.30 next morning!
