Hi all
Here's another from Sunday morning.
20x 90s lights, 10x 90s darks
+
20x 20s lights, 10x 20s darks for the core/trapezium
masked in Photoshop.
EQ6, ED80, 350D (unmodded), unguided, ISO1600.
Calibrated, aligned and stacked in ImagesPlus. DDP in ImagesPlus, noise reduction, masking and saturation/curves in Photoshop.
This one suffered more from the inaccurate polar alignment (due to the larger number of exposures) and after combining in ImagesPlus, you can see some field rotation around the corners, and in the hi-res version the stars are most certainly not round. Some of that is most likely due to the method I use to combine them.
Lucky for me though, reducing to 780px wide hides those nasties
Anyway I'm really happy with this image, it's a big step up from my previous M42 thanks to the longer exposures and dark frames.
Comments/critiques welcome, thanks for looking.
