I had a sniff at about 5pm that the clouds may stay away, so I set up, used the pencil marks on the deck from Thursday night as a guide and aligned quickly and then slewed to my target -NGC 3311 - all while cooking the roast beast on the barbie for the family feast.
All good - wanted to avoid the aggravation of guiding with Maxim so switched on PHD. Nice and solid guiding. Off we go.
And then it all went downhill. After 2 images the mount stopped responding. Took 10 minutes to work out there was no power. Why? I'd used the power from the pool filter box and it was on a timer set to turn off after 6pm.
Restart, align, start guiding - won't work.Wrestle with the mount, change balance, change aggressiveness settings etc. Still no good. Do a meridian flip - lovely tight guiding. Great.
Then the dew on the CCD window starts.
Raise the temp, let it sit, wander inside for a bit and try not to stew.
Back to it and - lost guide star. Of course the clouds have rolled in. Not big ones, just faint whispy high level cloud that you might not notice without a telescope.
Unpack, lug it all inside, notice the serious dew for the first time (am glad I didn't zap myself somehow!) and then realise that the building dust from home renos have infiltrated the scope - with the dew on the primary, the mirror looks like its coated in a thin layer of mud.
The bride has already finished the bottle of wine so no solace there.
And yet....
at 7am tomorrow I'll be checking the weather reports to see if there is likely to be a cloudless night tomorrow night.
Damn this addiction!!
