Hi Mark
If thats the case, do all the comments made so far equally relate to the ccds with the alternate cooling options? Like being less noisy; or being less affected by light pollution than a DSLR?
If we are talking mainly about noise, and the peltier fan and heatsink ccds are at one end of the scale (less noisy) and the DSLRs are at the other end of the scale (more noisy), do the QHY6 and MeadeDSI-III ccds slot in between. If so, are they close to the QHY8 end of the scale; in the middle; or closer to the DSLR end?
Hope all that makes sense.
Darrell
