ASTRO: another quick and dirty: this time NGC7K s2/ha/o3
I added three hours and 15 minutes of sulfur and two hours and 45 minutes of
oxygen to my one hour and 15 minutes of Halpha that you have previously seen The total exposure time is now 7H15min it is still grainy and noisy and this was only processed on my laptop. Expect a somewhat better version in the next 48 hours this was taken using the AP155EDF f/7 and PL16803 using FLI branded filters. They work great!

Richard,
looks great at this size, I guess the noise you mentioned only shows up in the full scale image. Stefan "Richard Crisp" schrieb im Newsbeitrag m...
