First is the ubiquitous M42. 5 x 5min subs, ISO 500 with 10 each darks, flats and bias. Canon 5D MkII totally unmodified. Focus was maybe a TOUCH soft, as I found my drawtube tension knob a little loose later on, but still pretty happy. Want to add about an hours more data, but how far can you take M42 before the eripheral cloud predominates? :) As is, the ghostly dust is starting to show, and that is ony 25 mins of data. I could stretch it in PS more, but it lost "the look". A bit over exposed in the core- may add my test sub to bring the core back ;)

Second is of course Eta Carinae complex. 2 x 10 min subs, ISO 500, same D,F and B's as above. Managed only2 subs before the clouds came over at 2am. Was hoping for 50 mins of light at least. I know some edge distortion - was not using a field flattener (will next time).

Working on the Horsehead now - 5 x 10 min subs. Real PITA with suburban mercury vapour lamps, and for some reason, my fluorite refractor does not seem to like the UHC/LP filter I am using much.
All photos through my beloved Vixen FL102S on an NEQ6 with an Orion Starshoot guidecam (which was having conniptions with Eta Carina because of the crud preceding the cloud bank). DSS stacked (finally found a setting I like), PS CS5.1 edited (levels, curves, contrast, vibrance, saturation). Was going to redux tonight, but of course, Mother Cloud rolled over again.
I would really appreciate sincere, honest comments from the pros out there - I am getting better, but a long way to go yet - CCD is on the list, but for now, the 5D MkII seems fairly sensitive to red anyway.
