Due to focusing issues the OIII data is quite out of focus which has left some strange teal halos around the stars (I used the Ha as the luminance which has half the FWHM). Was the first light with my ASI1600 and my first attempt at unattended imaging (automated focusing)... Need to get better at that last part!
