As was present with the old Long Camera a tube is required that contains the camera mirror and extends beyond the folding mirror to baffle light. It needs to have a provision for easy access to the Hartmann mask such as a slidable door, or equivalent. Action Log : January 13, 2000 1:26:57 PM gandreon More analisys is required. Tube may not be the best solution and it will be an heavy job. Currently the main source of parassitic light seems to have been cut (all LEDs off in Fiera). February 03, 2000 3:43:18 PM gandreon Tests performed by R Tighe were satisfactory. To be confirmed by Martin. February 10, 2000 4:22:45 PM gandreon A temporary solution has reduced parassitic light by a factor of 9. Therefore a permanent one should be devised. Deadline to be negotiated.

The report should include a proposal for the remedy of the imbalance problem. The study should also include the impact of the leak from the pistons on the stability of the telescope pointing. Action Log : Responsible : Mechanics Support Team Deadline : August 30, 2000 11:00:00 PM Deadline Status : Pending ________________________________________________________________________________ Telescope : ESO/MPI 220 Create-date : July 02, 2000 4:46:02 PM Problem Short Description : Check and repair dome for water leaks. Action : We found water acumulation on the telescope top ring. This water was discovered after tilting the telescope to the horizontal position for balance, at which time it droped onto the floor. Because we are not certain of the origin of this water, we request that the dome be tested for water leaks. Mirror is in rather dirty conditions only one month after re-aluminization because of water dripping on it. Thus, this is a very important problem to solve (FSE). Action Log : July 13, 2000 3:46:24 PM gandreon Delayed by bad weather. July 27, 2000 3:44:09 PM gandreon To be done this week. August 03, 2000 3:33:36 PM gandreon Holes have been located.

Action : Dome should be made reasonably light-tight. The rubber on the slit should be overhauled. Action Log : June 01, 2000 4:11:27 PM gandreon Emanuela Pompei wrote: as preliminary criterion for light tightness for the danish dome, I would say that if I take I a 5min I band FF with mirror and shutter open and no light on, I should get something of the order of the bias level (1200 ADU) and not a good flat (like it is now, 30.000 ADUs). June 08, 2000 4:13:06 PM gandreon Measurement of "dark" value (Flat field with no FF lamp on) in a similar telescope should be done in order to confirm that the requested value is realisitc. June 22, 2000 8:32:42 AM gihle The problem is related to the motor that activates the slit and the the actual rubber seal. As the slit is closed, the seal acts as a spring and force the slit to open. This can not be prevent by the motor that has no braking system. We are looking for a motor with brake that can be changed with the actual one. June 22, 2000 4:29:35 PM gandreon New deadline TBD when the motor is found or ordered. July 13, 2000 3:48:46 PM gandreon A suitable motor was found. To be mounted. August 02, 2000 4:08:32 PM gihle The motor found was not the correct one. It ha no brake, therfore we have to change our plans. August 10, 2000 4:13:09 PM gandreon Since we'll have a crane, a rubber strip will be applied internally to solve the problem.
