There were a few starry nights in the May, so I had a chance to test my complete astrohpotography setup including guiding. The common truth is – we want much and fast, so I had several targets, each one exposed ten times for five minutes each frame. And it quickly turned out that is not much for Canon 20D and it requires more time for each object. Anyway, first lessons learned, now its time to get coma corrector and do some flats.
Achromatic 70/500 guider works well, and there is no significant bending so far. PHD software is ultra easy and also do its job. Setting all up takes pretty much time unfortunately, however I am able to do it wihin half an hour (including GoTo calibration).
