I don't know about everyone else but I find it very hard to see the centre spot through the cheshire collimation eyepiece in amongst all the crosshairs and images on images on images.
Well I was thinking what would happen if I put an SLR lens on my DSI Pro, mounted it on a tripod and pointed it straight down the pinhole on the collimation eyepiece.
Lo and behold there is an easy to see image of all the reflections complete with centre spot displayed in all its glory on my laptop screen. Here is a picture of the setup and a before and after shot. Collimation is now a breeze.
