The next clear opportunity came with the intention to try for the Witchhead Nebula in Orion. This proved to be less than successful when I discovered that my current positioning of the guidescope wouldn't allow me to acquire a guide star for sufficient duration to expect a decent result. An unexpected visitor then occupied a couple of hours before I could return to any imaging. I noticed I hadn't previously tried M44 (Praesepe) with the apo so now was as good a time as any. The TV news had mentioned a chance of some auroral activity being visible so once I had started the imaging run I took myself off down the local fields where a decent north horizon was available. After 30 minutes peering at the sky with no signs of aurora I returned home to find the transparency had deteriorated a fair bit due to some washed out contrail drifting through so I stopped exposing after a dozen subs. Details: Megrez 88 apo. 12 x 5 minute exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
