From my understanding SBIG has 3 options for guide cameras:
- Remote Guide Head - Plugs into camera can be used with OAG or Guide Scope
- Internal Guider - STL Series Only (?) Has a second chip right next to the main chip...behind the shutter and filter wheel.
- Filter wheel guider - Pickoff prism in front of filter wheel but integrated with camera. I believe this is still exposed as a RGH or "EXTERNAL TRACKING CCD" as SBIG calls them.
I'll update my drivers and see how the STL performs as well as read over the docs (yay). Hopefully this evening but at least by this weekend. I can't promise that it will be the same behavior as an STT or STF...but it "should" be.
It's been a LOOOOONG time since I did the SBIG guider implementation. I do seem to recall now that the shutter was a little weird when using the remote guide head...but it's honestly been too long to recall.
Thanks,
