After a big 50th Birthday bash last night (for moi
) I was looking forward to recovering with some image processing
. Just sat down to put together about 15hrs of data...and after doing all the preprocessing...wondered why my brand new set of flats wasn't working properly for my OIII calibration, then I realised when I had re loaded my Astroart software recently after a hard drive failure, I must have assigned the wrong labels to the filters in the filterwheel control panel? Lo and behold when I used the SII flats (collected before the software reload) my OIII data flattened out beautifully. So my 6hrs of OIII was actually 6hrs of SII
..Dang! it was OIII that I wanted because it is a tiny Planetary
...I wondered why the OIII data looked so similar to the Ha
.....now I need another night...and the Moon as growing fuller and the weather isn't looking good over the next three days, I need no Moon for OIII...fun hobby
