OK, since we're looking at Orion, here's mine from Dec 24, 2011:
Image details: An extensive rework of this set of images from Dec 24, 2011 at Montebello OSP.
Taken with my full-spectrum modified Pentax K10D camera using the Stellarvue SV4.
Guided with PHD using the Orion SSAG on a SV70ED. Sitting on a Losmandy GM-8 that I've recently upgraded with the OPW and high precision gear.
Stacked with DSS using:
Stacking step 1 ->2 frames (ISO: 100) - total exposure: 1 mn 56 s
Stacking step 2 ->6 frames (ISO: 100) - total exposure: 11 mn 54 s
Stacking step 3 ->3 frames (ISO: 100) - total exposure: 15 mn 0 s
Stacking step 4 ->1 frames (ISO: 100) - total exposure: 10 mn 2 s
Processed with PixInsight. DBE, 50 iterations of Masked Stretch to .09 median value and then another 50 to .1 value. Slight histogram stretch to tweak. Exported to LR3 where I did final touchup.
This one made it into the Pentax Photo Gallery.
