This is taken with the Canon 10D at f5 through the LX90, IDAS LPS filter, guided with the STV autoguider. 4 shots at ISO 800, 8 minutes each, calibrated with adaptive dark frames (ImagesPlus), registered in Registar, and processed in Photoshop 7. I purposefully didn't enhanced color too much- I like a more subdued look for this nebula. Hope you like it! Steve Cannistra --- End forwarded message ---
