Hi All
Well, I have finally taken leave of my senses, I knew it was going to happen sooner or later what with with all these sleepless nights. I know that narrowband imaging is more associated with emission nebulae, SNR, planetary nebulae and the like but I decided to do this as an experiment while I was waiting for IC 443 to come from behind my house. The moon was almost full so the sky was very bright and as I already had the emission line filters loaded in the filter wheel (LRGB set is still in the boxes), so I did 6x10 minutes unguided for each filter and combined it SII=Red Ha=Green and OIII=Blue (HST palette). Although I wouldn't recommend people spend valuable imaging time taking pictures of star clusters with NB filters I am always wanting to try new things even if they don't sometimes work, I am reasonably satisfied with the way that this has turned out although some of the colours are a bit more muted than what I have seen elsewhere. I last did this late last year with a WO 66 and Starlight Xpress M8C and this image can be seen for comparison in the star cluster section of the image gallery on my website

Further details about the equipment used is also on my site with the image
Thanks for looking
Best wishes
