Short? No way. This is no CMOS super low read noise fancy shamncy but ole fashioned large pixel rev head large full wells super charged.

John Gleason does 40 minute subs for his FSQ and Ha images.

105,000 electron full wells means you can go very long exposures without filling them. The 16803 has great dynamic range and rarely overexposes an area.

You'd have to really thrash it to do that. Full well capacity is often not considered that important but in my experience its very important.
