Hi,
More experimentation with ISO 6400 with 1600 for blending.
It's quite tricky to tame the blown stars, I was partially successful.
ISO 6400 really gives vibrant colours!
I've also supplied the original stacked 6400 image from DSS to show the level of burn out with stars and core.
8" F/4 astrograph HEQ pro 5 mount. Orion mini guider.
Unmodded canon 1100D, baader type III coma corrector.
20 x 2 minute subs ISO 6400 and 5 x 2 minute 6 x 30 sec ISO 1600. Stacked in DSS, processed in PS Cs2.
Image cropped.
Cheers,
Justin.
