With recent clear nights I did these
Eta carina Neb, 2 x 10 mins ISO 1600
Horsehead nebula, same
Both with 10 inch F5.6 off axis guided, Coma Corrector and UHCS filter Eos 300d Unmod. I manually subtracted darks with Photoshop CS by adjusting the levels of the 3 colours of the Dark to avoid coloured spots on nebula. This seems to give best results.
Weather around 20 degrees.
