Ross,
Thanks for the compliment!!
I've already started on a rework of this data taking into consideration Marcus' comments and his fantastic image. I've improved in several places, however I'm now just trying to work out a methodology to tame my blood-shot stars. I'm almost positive that the UHC-S filter I use to tame the LP is reducing the yellow in my images but I guess this is one of the things I have to deal with living in the middle of Brisbane!! Anyway, when I'm happy with the result I'll be posting it here - don't you worry about that! (Hey, I live in Queensland with the ghosts of Joh...)
However there are a lot of positives that I take from my latest night under the stars. Firslty, I am very happy with my new rig, the GSO RC8. Not only does it do a fantastic job at capturing those photons, but it holds collimation and focus well. I'm impressed at how sharp my images are compared to the newt, pre-processing. Also, at half the length and about 2/3 the weight of my old 8" newt, it's a lot less of a strain for my HEQ5 Pro mount.
Secondly, I'd made some slight changes in my PHD parameters and I no longer seem to have guiding issues. I'd lowered my calibration step from 2000 to 1000 and it seems to have worked a treat. MY alignment was also nearly spot-on with PHDLab giving me a mis-PA of 3.84 arcminutes, not quite 1/15 of a degree. Thirdly, if I could get this baby to a dark spot then I could ditch the light pollution filter and get some yellow back into my stars!
Well that's enough from me - as I mentioned before, stay tuned for a repro...
Cheers,
Mario
