It will give greater functionality, and the use of a common system at all three telescopes is expected to reduce maintenance costs. In conjunction with the new CCD autoguiders at cassegrain and prime, the closed-loop tracking performance of the INT will be improved. Jacobus Kapteyn Telescope 23. A more detailed breakdown is given at Annex 1. 24. Bi-monthly CO2 cleaning of the JKT mirrors continues with encouraging results.
Light leaks are still evident when imaging with narrowband filters.
Filter masks, similar to those used on INT prime focus, have been manufactured to eliminate such leaks. Two bulky and noisy electronics racks have been removed from the control room, giving a far quieter working environment, and more workspace. Work is underway on new primary and secondary mirror support systems, in order to bring the optical image quality of the telescope within specification. This work is expected to complete during 1997. May. The results from this run are likely to be important in determining the direction of future instrument developments on this telescope.
