Newbie here. I have a TMB 105/650 CNC telescope, focal length is 650mm. The 174 chip-based cam has a 5.86u pixel size and will produce a 1.86" arcsecond/pixel size based on my FL. The 183 chip-based cam has 2.4u pixel size, 0.67" arcsecond/pixel

Which one is the best match for my scope. The camera will be used primarily for solar and lunar photography only. Thanks :)
