We had a lot more haze in the sky today and the result is longer exposure times as well as more detail loss.  Especially with the faint prominances at the limbs.  Having a larger aperture such as a 90 would help in better bringing out these details I expect, but my 40 mm did not bad either.  Today AR1232 is still visible and 1234 with some faint proms in H-alpha and CaK.
