Stupid weather, it's cloudy up to midnight but then thins out until near dawn. Even at 3 am the air temp was 27C ! I'm surprised I can get anything with it. Anyway, this is Eta Carina from my new toy, 8" F4 Newtonian, steel version. I love it and hate it all at the same time lol. This beast is going to take some taming, so please excuse the worts that I'm sure will plague all my images while I get used to the thing. The flat still needs some adjustment. I've been spoiled by my nice refractor.
Acquisition details: 107 x 30 seconds between clouds at ISO 1600, 8" F4 Bintel Newt, Baader MPCC MKIII, HEQ5 Pro unguided, standard off the shelf not modified, not cooled Pentax K-5. Image has not been cropped. This is 100% of the frame, edge warts and all.
