Ok I have got a copy of ezycap (2.4) something to be aware of is that the planner table and the capture output vary.

You should shoot ALL your frames through the planner table, even though the settings are done through the capture tab.

Offset settings is so that during a bias frame ( fastest possible fully covered frame) you should get a reading that in a histogram shows a value of say 600 give or take it will be a bell shaped curve that MUST have all values greater than 0 preferably >400.

Your gain setting will be set by doing a fully exposed shot say 5 sec with a torch shining down the tube of your scope, you can do 10 and more just to check. But you will possibly find nearly all pixels at one value, it needs to be set so value is about 65000, if you find your max value is 58000 or so you will need to increase the gain.

The two can be somewhat interrelated so go back and forth until set right. Again you must do this through the planner table, I found doing single exposures through just the capture tab to be WILDLY different.

Hope this helps.
