Here's my take on NGC2392 (aka the Clown, Lion or Eskimo Nebula) -this tiny but quite interesting planetary nebula in Gemini. After doing some research I found some very nice results some others had achieved with short exposure but unfortunately being quite low in the sky and through the Sydney heat-haze, I just couldn't get good bang for buck so elected to shoot with shortish 30sec sub lengths instead.
I shot over 5 nights, about 2hrs each night around it's peak of 35degress, and manually sorted each sub to get only the best quality data. My criteria was being able to see the clear divisions in the central bands in each sub - and after this ended up with 2hrs of data for processing.
Not sure I exactly nailed it, but also not sure I can do much better from my location and with only 2hrs integration so will have to leave it there for this season.
