Thanks for the kind words guys. Bob, I couldn't be more thrilled. A lot of the problems were with FocusMax failing. Turns out there's a table that defines the minimum and maximum exposure times. Those maximum exposure times were way too short for narrowband imaging, causing the focusing to fail. I upped the exposure table times up to 30 seconds as well as increasing the base minimums. Now, FocusMax is working with individual exposure times upwards of 13 seconds. Now that FocusMax is working, everything else is falling in line.
