    Default The thing stopped during the night...

    God Morning (at least on this side of the ocean).

    I am currently in the "pre-purchase" phase and have my new observatory control center running with a full compliment of ACP stuff. I use the ASCOM simulators for scope, camera and focuser, and the ACP weather simulator to get myself and my stuff in order. A two-foot startup script and a dito shutdown one have been added to the schedulaer and I have submitted three observations.

    At around 17:00 yesterday the scheduler started acquiring images (59°N, dark comes early) and when I went to bed all looked fine. This morning I find that an overflow has occured in one of the ACP-supplied scripts when a CInt operation was attempted. Looking at the code:

    Code:
        Console.PrintLine "    [flip check: " & _ 
            " Tn=" & CInt(timeNeeded) & "s" & _ 
            " HAc=" & CInt(Util.HourAngle12(Telescope.RightAscension) * 3600) & "s" & _  
            " GW=" & gw & _ 
            " HAz=" &  CInt(Util.HourAngle12(z) * 3600) & "s" & _ 
            " DWz=" & dwz & _ 
            " WF=" & wfs & "]"
    And the log section:

    Code:

    So, one of the three CInts in that multi-line statement is going past the 32767 mark. Which can it be?

    Luckily, the system recovered from this and continued with M 81, and I have verified that there were actual images.

    Let me know what further information is needed in order to find it (complete log attached)!

    This is my very first run of ACP and I am truly impressed so far!


    All the best,
