Re: Close up of M81 without CCDT67

How good would 2.5um pixels look on a 2.5m focal length at 0.21"/pixel? Pretty good provided you have the extra time that will be required to expose the target and if "normal" seeing for you is also in the realm of "pretty good." You'll certainly have the roundest stars on the block, assuming your mount and other mechanics are also up to the task.

Oversampling isn't inherently bad if you're blessed with time and stability. Most people in that situation would start at 2x2 binning, maybe 3x3... at which point you must ask yourself if you're really using the right tool for the job because you would be paying for a lot of sensor real estate that is being used just to make up for the time and conditions.
