Eta Carina in Ha: now with Fickle Finger
Just before the latest deluge I managed to get 7x10 minutes of Ha on Eta Carina. It will need more data for sure as well as colour but I was amazed at how much detail was in the frame. It's spoilt a bit by compression etc and I know its an easy target but I wanted to fiddle with the reducer spacing as well as set up with the DSI guiding through the QSI-wsg for the first time. I was having problems with differential flexture (I think with mirror flop) but internal guiding sorted it out for the 10min subs. No flats, darks or bias frames -didn't have the time.There is still eggy stars in the corners but not as bad as it has been.
