'Stiletto' Focusers - Anyone got one and using it ?
Found this by accident - looks like a nifty accessory for prefocusing prior to using the Autoguider :

STI Autoguider Focusers were developed by Stellar Technologies International to specifically overcome difficulties in focusing the SBIG ST-4, STV, Meade 201XT, Meade LPI, and Meade DSI-C, Starlight Xpress, and Orion StarShoot cameras.
I did use one some time ago for my Pentax *istDS DSLR and it did work as advertised.
However, I found it fiddly to fit the Stiletto device, focus it and then remove it to attach the Pentax camera. Now that I have a Canon 40D with Live View and my trusty Bahtinov Mask, I can achieve perfect focus more efficiently without that fuss.
I did have one early problem with the Stiletto system (no fault of the Stiletto) in that the T-Adapter on my Pentax *istDS had some play in it, which resulted in incorrect focus after the Stiletto had registered the correct focus. This was due to the slop in the T-Adapter which was fixed when I purchased a better manufactured Vixen T-Adapter for the Pentax.
