Sounds like one of those nights,
last night i tried ngc 4945 a nice little galaxy, lined it up took several test shots all good so far, turned on the guider (phd still calibrated from last run,) shoot 3 x 6 min frames only to find not tracking properly, tried recalibrating only to discover i left the hand controller in the port from lining it all up
ok so i put the guider cable in and do another run, guider drops out, another image not tracking properly, why???? apparently when the cable was out of the port the guider being unable to guide switched off the DEC guiding in the settings panel
ok so i do another run after an hour since i set up the run the focus has gone.....

its too late in the morning and at 3.30 theres not enough time left to do a full run...... i gave up
Going to realign the guidescope to the main scope tonight, i dont want any stuff ups next time round.
Still i enjoy my hobby ....next time.... cant wait.
