Only had time for 3 subs before the clouds rolled in. Not bad considering…

Reprocessed by stacking with frames taken from 20th January 2010 unfiltered. A total of 40 frames stacked. Far less noise and more detail. Had to crop much closer though because of rotation stacking issues.
M42

An experiment to see how this would come out taken with an f/15 Mak-Cass. Certainly not what you’re meant to use for this type of object. It means you can still actually see the trapezium.

2009-01-28 C80ED f7.5 Canon EOS 350D
Guided with ETX-90 Mak-Cass at F7 and SPC800NC unmodded using PHD
2x5m, 5x4m  5x3m 1x2m subs ISO 800 Lumicon Deep Sky filter
Calibrated in DSS, manually stacked in PhotoShop CS3, processed with Noel’s Actions
I find DSS is not giving me good results but manual stacking in PS CS3 is much better for me. I do the calibration and darks in DSS as PS is not good for that.
