While set up with the apo a look at M42 was an obvious choice. At least there are no difficulties finding the Orion showpiece as just a few seconds exposure show it clearly and hard processing is definitely not neccessary. Indeed it allows so many options that choosing a version to post is the biggest problem. I took a variety of subs from 10 seconds to 10 minutes. Details: Megrez 88 apo. 15 x various exposures @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
