On the brighter stars the ADU is the limit at 65535. I swapped my U16M and now have a brand new Proline 16803. The cameras give 2 different image scales much like having 2 scopes one long focal length and one shorter. The smaller chip is better for close ups and the 16803 for wider field. The 8300 does max out at 65535 more easily and bleeds harder hence the bloated brighter stars. Perhaps shorter subexposures is in order then. Maybe I should use 5 minutes instead of 10 minutes.
