I thought about packing up, but checked all kinds of weather channels:
One says clear all day and night (and it's destintively not clear right now!)
One says clear from 5pm.
??? What to do ???
5:15PM: I decided to stay. And the clouds seem to get thinner!!!
... and it totally paid off: one of the best nights ever!!! Clear skies, no clouds, and pretty much everything went well with the equipment. I could finish my image of IC 1318. The Baby Eagle image needs some more data (lots of noise in the background but also in the nebula itself):
But I took an ultra-wide angle of the Cepheus region with my Polarie:
I should really get my camera modifies - or buy a second without the IR filter. This region has A LOT of nebulosity but you need to look very carefully to see it :-(
