-Faulty encoder in the Y axis od the guide probe (must be fixed)
-Iman camera images first were saturated without light, then were scrambled...problem with video cards and frame grabber supposedly.
-nevertheless, putting the guide probe in the center field (by hand in the Y) and using the guider camera 2000, the TCS software fixes were implemented (e.g. maintain coordinates after offsets during active M2 corrections)
-starting around 2am after it became clear Iman would not work, a donut skymap to check that M2 correction is happening all over the sky, was done using the SBig camera. All sky was covered.
