Just by way of feedback. I used that calculator for my CDK and Trius. I set the min move to .5 like it recommended up from .1 that I normally use. It worsened the images quite a bit. My guide errors even with PEC and Protrack on are .05 to .3 for 80% of the corrections and the rarely over .5. So that meant it was not being corrected for 85% of the time if not more.
The bottom line very often with these types of calculators etc is its hard to beat empirical testing - ie. the actual performance as opposed to a theoretical. Trial and error whilst slow tends to get you involved and you know what is best for your system under various conditions.
For my PME with a guide scope at 2 metres its 2 second guide exposures, .1 min 2 max move. aggressiveness 6.
At 3 metres and a MMOAG it is 5 or 6 second guide exposures and same min/max.
Both with PEC and Protrack (300 point model) on.
For PMX I use about 5 second exposures with MMOAG, 6 or 7 aggressiveness, .1/2 min/max at 1260mm focal length and PEC on (no Protrack as I don't have a good enough model yet). If its a bit windy I would reduce guide exposures to 2 secs. No delay on any of these. Direct guide on all of them. Quite an accurate polar alignment on both and of course this is the first step to get perfect and worth the effort.
