FLI PDF focuser
I bought this so that when I am imaging I can set up a rough focus on the telescope and then with the aid of the FLI focuser I can sit at the laptop and get a more accurate focus. It only has a focusing range of 0.5 inches but it can do this in 7,000 steps which gives some idea of it's accuracy. As yet I haven't tried it out properly due to time constraints and waiting for brackets, adapters, etc so the setup can be more permanent.
Telegizmos 365 day cover
I sometimes leave the telescope set up outside for days at a time if the weather is looking promising and the Telegizmos cover ensures that no nasty weather causes problems to the equipment. I can thoroughly recommend this accessory, it has protected the scopes and mount from rain, snow, frost and wind and not the slightest bit of moisture or condensation has managed to get to the equipment. They can be got through Widescreen Centre in London.
