Hi,
Here's last nights efforts, IC 4601 in scorpius and NGC 253 the silver coin in sculptor.
IC 4601 was a challenge, just to get enough data, let alone processing to bring out the background dust.
It was one of those nights where murphy's law was in full force. Cloud coming and going, forgetting to switch on the auto guider! I wasted a few frames on this. Then when I went to image NGC 253 I managed to trip on the main USB cable to the observatory, which screwed up the auto guiding. So I went for 2 minute unguided subs.
IC 4601 is interesting, for want of a better word it's the first white nebula I've imaged.
IC 4601 75 minutes of data in 5 minute subs ISO 800.
NGC 263 30 minutes 2 minute subs.
Darks, flats and bias applied to both, post process in PS.
Cheers,
Justin.
