Distributed as part of the ASCOM package is the FocusAPI plug-in for CCDSoft. There are some basic instructions provided to get FocusMax integrated. The plug-in enables CCDSoft to communicate with an ASCOM focuser, by translating the FocusAPI calls from CCDSoft into ASCOM equivalent calls.
Bisque's @focus 2 capabilities I believe are now comparable with FocusMax. @focus 1 was rather lame. FocusMax is still evolving (as is @focus) as per my previous post
(FMx 3.4.1 released). I don't think either have the edge on the other. Depends on your preference and ultimately whether the software gets your camera's focal plane into the CFZ
every time.
If you're scared of ASCOM and prefer to stick with proprietary code such as that developed by Software Bisque. You are stuck with @Focus 1/2 for automated focusing. I'm not saying that's a bad thing, but I feel its important to have a choice. ASCOM opens up a wealth of device support.
