Another problem with the MX has been that it's clear SB never tested it in the Southern Hemisphere. That's assuming they even have a test suite. They probably don't have a dedicated software QA person. Their development methodology is rather suspect to me. As with many small companies, I don't think they actually follow a formalized software development methodology.

you need to setup the FOV indicators in the Sky X

For image link? Huh? What are you smoking there?

index error out of range error 731 (no reference in the manuals as to what that means).

That's the pointing sample criterion advanced setting that was alluded to previously. It needs to be increased, especially if you have a scope with a low focal length or a camera with a large chip. The default pointing sample criterion appears to cater to those of us with long focal length instruments and small chips.

Sky X appears to want the value based on the binning you are shooting - I may still not have that right though!

Correct, TheSkyX image link wants to know your guesstimate of the actual image scale, not the 1x1 binning image scale, the actual image scale. Entering 0 and letting image link figure it out is often better than guessing. I don't remember TheSky6 being any different, but it's been many years since I used TheSky6 on a regular basis.

The camera window where you can change binning etc was clicked off at some point and its unclear where to reactivate it.

Huh? It's clear as day: Display->Camera

The camera tab that comes up if you do this is a different one that does not have the ability to change binning. Apparently there are 2 camera tabs not one - very confusing and hard to find in the software.

Second camera tab? Hmm. Maybe you're referring to the automated calibration settings and the fact that although you can set the exposure there, you can't set binning there. It uses the binning as set in the camera tab and if the camera tab is not being displayed, then you'll not know what binning you've set there. Yes, that is confusing. They should let us set the binning in the automated calibration settings. Please do me a favor and suggest this as an enhancement. It's already been suggested, but continues to fall on some apparently deaf ears over at SB! (Just wait until you realize that other settings, such as which filter you're using, are also set only in the camera tab. Good idea to have the camera tab displayed.)

The PMX manual is a superbly written document and I have to acknowledge it is one of the best technical manuals I have ever seen. However it is not complete and you will still need access to fine details when things go wrong that are not in the manual.

When you find an area of the manual that has incomplete information, doesn't have information that you think it should or could include information you think would be helpful, document the additional information in detail and post it as documentation errata for Daniel Bisque to add to the manual. Post it publicly on one of the SB support forums so that all may benefit (via search if not directly). If everyone would do this, then the manual would get better very quickly and the newbie frustration level would decrease (for those that actually read the manuals).

I'm starting to get the impression that a contributing factor to your MX frustrations is your TheSkyX learning curve frustration. Those are two different things that should not be confused.
