Eta Carina Nebula. Relatively short amount of exposure data, only 3 shots. Also the telescope was slightly out of focus, but I was in a rush getting what I could before a storm rolled in.
It is quite clear comparing this shot to the Megrez shots that the Megrez has significant blue fringing on bright stars where the FLT 110 has none.
I did not use the field flatenner (which is supplied with the FLT110) for this photograph and hence the edge distortion is about the same as that

I did not use the field flatenner (which is supplied with the FLT110) for this photograph and hence the edge distortion is about the same as that of my Megrez 80. I'm confident that with the field flanner that would be removed. This distortion is not really visible in the small versions shown here, only in the 2.5mb version that I can't justify putting on this site.
