My image of NGC3132 or the Eight Burst Planetary Nebula taken with 8" SCT with 6.3 focal reducer on the G11. Autoguided using PHD and an 80mm achro + QGuider.
It has been a while since I last posted an image. I think that I have nearly solved all of the little issues associated with polar alignment and set-up of the G11. There appears to be some field rotation so I still need to work on the polar alignment.
I used a 2" IDAS-LPS filter to reduce light pollution. Image taken from my suburban Perth location.
Exposure of 2hrs (using 3min subs) with a modified Canon 350d @ ISO800. Dark, Flats and Bias used. Image stacked in DSS and post processing in PS.
Any comments or suggestions greatly appreciated.
