Re: Comet like Ring nebula, or a planet

What tempereature in Celsius is optimal for CCD?


This isn't an ideal object for video/webcam imaging. It is too dim for
such cameras, and it is too large. The highest detail images are likely
to come from short exposures, possibly stacked, made by cooled CCD
cameras with moderately large sensors.
