Not wanting to waste the last few minutes of darkness...I sqeeeezed this in, just before sun up this morning

Normally the last hour of darkness the seeing steadies right out here...but in this case I couldn't believe how quickly the seeing deteriorated It was quite ok when I finished the main imaging session (another galaxy ) but by the time I slewed over to the Hunter it had fuzzed up noticably, so I decided to do it in narrowband to maybe save some resolution? While the seeing for the Ha was very average, for the SII it was crap and finally by the time I got to the OIII man! the focus star looked like a pom pom and it all happened in the space of a few minutes ....it was like something was wrong ...about as bad as the worst seeing I saw in Newcastle ...oh well just for fun I threw it together anyway because it was such a simple processing job. At least I could reveal all six main stars but I will be able to do much better under the normal seeing conditions I get here
