Subject: Re: [Astro_IIDC] New GX camera
Just a note.. PGR now FLIR sponsors my nonprofit solar Astronomy program with Grasshopper xpress cameras yearly. We give away imaging setups routinely.
All of the FireWire 800 native cameras work flawlessly on our 2009-2013 Imac’s using the last version of ASTRO IIDC on the golden key. None of the USB native GX cameras will work even with a converter cable.
The only Macs I have seen them not work on intermittently are MacPros like mine with after market video cards. Mac pros with souped up video cards will also not stack .mov files at all.

Hi Phil;
Those cameras did not exist when Astro IIDC was last tested, so it’s hard to say if it will work.
A few things to check, besides what Stephen suggested.
Are you using a FireWire 800 to FireWire 800 Cable?
Does your Mac have a real FW800 port or is it using those Thunderbolt to FW800 converters?
Are you using the last version of Astro IIDC? Those cameras are all FW 800 IIDC 1.3.2+ compliant and earlier versions of Astro IIDC may not support all the modes.
Check the Console log and see if there are any error messages being reported for it.
Lastly try using a smaller video size and / or a lower frame rate too.
HTH..

>> I just purchased a new Point Grey Grasshopper Express camera, firewire version to use with Astro IIDC. Plugged it in and was recognized in Astro IIDC with a lot more options than my old DMK 31 cam. Now here's the issue, I get about 1 second of live video before it freezes. If I change shutter speed or frame rate I get another second of video before freezing again. Seems like it loads and reads from a buffer then stops.
