Hi All,

Just received my Microline camera.

It has a Mode1 and RBI flush readout modes.

The latter takes much longer to download.



The two modes does pose a problem for automation.

For fast downloads, you want the normal mode for pointing & synch, focusing, skyflats, etc, but because you want RBI flush for imaging, you have to set the readout mode to the latter, losing the fast download benefit.



Anyone have a work-around for this problem?

I use ACP.

ACP supports readout modes through MaxIm DL's features for same. Please read the

info under ACP Help, Using Imager Readout Modes, or simply search in ACP Help

for "readout mode" and pick the first result.

Hi Dale,



Not sure what problem you are having



The RBI feature has nothing to do with download time. What it does is to flush the sensor with infrared (if I recall corectly) light a specified number of times for a specified time in order to reduce ghost images (electrons trapped in the photosites of one image that stays for the next). After that is done there is a normal download. Thus the RBI feature does not change the download per se. It does however change the time needed between two images.



My guess is that your problem is to automatically changing between the two modes from within ACP?



I do not know about ACP, but in CCDAutopilot you can set the mode you want for focusing, positoning and imaging.



To me this should be handled by ACP, CCCDAP. In other words to me it is not a Maximdl issue. But maybe I missunderstand your question?

Hi Matts,

The RBI feature does indeed add time to the overall process. Depends on the binning.

Fortunately I have discovered that ACP can be set to distinguish between the shorter (Mode 1) for focusing pointing etc. and the longer (Mode 1 RBI Flush) for imaging.

Yes! And for data images, yu have the choice, and can control it within the ACP

observing plan.
