Camera change on P3, Mount fix on P5

Filed under: PROMPT-Related, Telescope & Camera Status — mrbook2 @ 4:36 pm

The camera on P3 is having shutter problems, so for the time being, we have moved the camera from P2 (which is awaiting a replacement computer) to the telescope P3.  The most important thing this means is that you should NOT USE old calibration images from P3 on new P3 data.

We think that the really bad mount issues on P5 are mostly resolved now.  PEC has been modeled and the correction implimented, and it seems pretty steady now.  Let us know if you see more double and smeared stars (it had a PEC drift of about 7 arcseconds over 2.5 minutes, so you will know the problem when you see it.)

We have been seeing some weird errors from the focusing system, so if you happen to get an image that is horribly out of focus, let us know.  This will help us track down when the problems are happening.
