.....don't mess about when great opportunities come along. Great skies tonight and what did I try to do? Something different that's what. I thought I'd mount the camera with the stnd 75-300 lens and guide via the ZS66SD. Nowt but so**ing problems. Co-aligning and focusing being the two biggest probs. Which do I align as primary with the mount or does it matter ?-ummm well surely it should when it comes to synching the mount with planetarium s/ware. Anyways, having gone out in bare feet and slippers, thinking it wasn't going to take long......2hrs later and frozen tootsies and nothing achieved, other than highest order frustration, I packed up. Shiess what a waste !:mad: Shan't try that again for a while
