Thanks Warren!
My focus problem may be more a ID-10-T error (yes, it spells idiot).
I don't understand Sharpcap and therein lies the problem. I got perfect focus on the moon last night but had trouble with star fields so it's my miscomprehension of the software or how to use it. The moon was after attempting focus on stars and with a different lens (80-200 f2.8ED Nikon) I had been using a 35mm f 1.4 Rokinon on star fields. I had however checked focus during daylight and having no problem. However once I pointed my 200mm already infinity focused lens at stars I got nothing on the screen. I really have to read up on how to use the software.
This after years of using SLR and DSLR cameras for astronomy, the little dedicated unit requires software I just don't seem to be able to get settings right in.
In saying that you may have noticed the Polemaster mounted on the Astro-Trac, I got to try it out with my sons help. The screen came up and said "Rotate the RA around 30 degrees in the direction of the arrow". It's not a proper astronomy mount (obviously) and I started rotating the Dec axis instead while watching the screen expecting the software to give me an alert when I was close.
Well that never happened and now I'm going to RTFM and get my axis correct (I do know the difference, I'd had a stressful day).
I completely messed everything up and just packed up (I was crook and really shouldn't have been out playing).
Plus I'd levelled the head not the tripod in a sloping yard and that was a major mistake once the head was rotated. Now I'm determined to get my pier in within the week, I'll order the aggregate tomorrow from the local landscape supplier and buy cement at Bunnings. I have 5 bags here, probably old but I'll break one or two up in my pit with gravel in it and tamp it down with the crowbar (today) because of the clay, it absorbs water out of the concrete mix and destroys the final result. My gravel and cement mix should theoretically prevent that.
