Hi
This is the first full narrow band image that I have done with my new ML8300 camera as weather hasn't been playing ball lately. It is of IC443 taken in the wavelength ordered palette of SII:Ha:OIII = R:G:B (commonly known as the HST palette). It was taken over three nights with 10x30 minutes for SII, 11x30 minutes for Ha and 9x30 minutes for OIII. We have had a lot of problems with freezing fog recently and the seeing conditions were very hit and miss on all three nights with the FWHM number varying between 1.3 and 2.4 from one minute to the next, it made focusing quite interesting!
Taken with Takahashi FSQ106ED f5 and FLI ML8300 on a Paramount ME with auto guiding by a lodestar and OAG using dithering. I may add some more OIII data as this was very weak and needed to be pushed more aggressively in the processing so there is a bit of noise in the image but overall I'm fairly pleased with the results. I added the difraction spike on after for extra effect, the ML8300 and FSQ combination often gives smaller difraction spikes (?due to the microlenses on the chip)
I have had a few goes at this subject over the last few years with different scope/camera combinations, these can be seen on my website
