Got things going eventually last night, cloudy UK skies being the problem until now. After my previous experience I wasn't expecting much but everything went pretty well, the mount slewed to target well and astrometry was obtained probably 95% of the time. When I started stacking I was astonished just how quickly and vividly images appeared on my Ipad, there is obviously some fine tuning to be done.
The problem is that absolutely no images were saved. I have read the relevant sections of the online manual and it seemed to suggest that images are saved automatically. Luckily I took screenshots of each target but I would like to record an image just for record purposes. Be grateful for any ideas.
