OOPS!!! CHECKED MY DATA AND FOUND THAT THESE SHOTS WERE DONE AT 100mm NOT 280mm AS POSTED!!!



:ashamed :
Hello all,
Bit of an experiment - wanted to see if the Witches Head Nebula could be captured with my DSLR.
Verdict - very tough!!
Total of 9x10min subs (need heaps more),280mm f5.6, iso1600 ICNR on, Flats.
Canon 40D modded
Canon 70-200mm f4L + 1.4x extender, Hutech IDAS LPS2 filter.
Skywatcher Synscan EQ5 GoTo mount.
Autoguided with PHD
Had to do some rough ad hoc processing - removed starfield from one image to accentuate the nebula then recombine with the original image.
My skills in this area are poor so apologies for the roughness of this one!

All the best, any suggestions gratefully accepted.
