Diamond Form Drive System
I bought this as a replacement for the Skywatcher ED80's stock crayford, along with the 97mm adapter and ClickLock. After an initial struggle with the ED80's unwillingness to part with the old focuser, resulting in a sheared screw head, the Baader kit was simple to install (I'd already sourced some M3 x 8mm hex screws):-Adapter to the tube with 3 screws-Focuser to the adapter with 5 nylon grub screw / bushes and 1 lock screw (for rotating the focuser). Careful with these, but there are spares provided-The ClickLock attaches to the draw tube with 6 grub screws (Allen key provided)The action is very smooth along the 80mm or so travel, and I was able to transplant my Sesto Senso motor with minimal fuss. This focuser adds a premium feel to the scope, with strong, accurate and repeatable travel. Well done BaaderI only wish I'd done this sooner!
I bought this to replace the stock focuser on an new Skywatcher ED80, which had proved to be defective from the off, and I'm very pleased I did. The SteelTrack focuser compliments the excellent optics of the ED80 perfectly and gives the whole scope a premium feel. The mechanism feels positive and smooth to use and oozes quality. There are a couple of niggles that might be worth considering if you intend to buy one of these. 1. The unit I received didn't come with any fitting instructions and it took me a few minutes to work out that the you had to remove the existing plastic grub screws to fit the focuser to the correct flange before mounting it on the telescope. 2. There is no finder shoe provided. So I bought the Baader Standard Finder Base to mount on the focuser housing. This is done by removing a couple of plastic blanking screws to reveal M5 threaded holes beneath. Unfortunately neither the focuser nor the Finder Base came with mounting screws and there was no indication in the accompanying guide on what length of screws to use. After some experimentation by cutting down some old M5 screws I already had I determined that 6mm to 8mm was about the right length without damaging the internals of the focuser itself. Once I'd determined that, I bought a packet of black 8mm M5 Hex screws from eBay and the Baader Stander Finder Base is now fitted perfectly.Other things to note; the focuser is rotatable, even though this doesn't seem to be mentioned anywhere in the documentation I had. By adjusting the plastic grub screws used to attach the focuser to the flange you can modify how easy the focuser is to rotate. There is also a knurled locking nut to lock down the rotation once it's been adjusted to suit. Also, it's worth buying the Baader Click Lock adapter for this focuser as it makes fitting and removing the diagonal and other accessories a breeze.Despite a couple of niggles I'm very happy with this after-market focuser. Highly recommended.
