A couple of clear hours!

Unbelievably there were a couple of hours of clear sky (and no Moon) last night 🙂  As both the mini-WASP and the new Hyperstar III setup need tuning it was a hard choice of which one to work on.  Expecting to finish the Hyperstar III and maybe even grab an image too – I went for the Hyperstar.  Needed to refocus-train the system as there is a new camera on board, and then it was the old collimation routine.  Got to a point of pretty good collimation but poor star shapes around the edges.  Think this needs another bit of optical hardware to get rid of that – so next outing I suppose.  Three hours work done before the clouds rolled in – can’t complain – better than nothing.

    So what’s the extra bit of optical hardware to help with star shapes?

    It was an extra aperture that I have now removed as I took off the little fan that bolts to the side of the M26C CCD. The aperture “hid” the fan.
