Successful Shutter Seal Replacement

By admin - Posted on 03 July 2018

In preparation for the shutter seal replacement, the Blue Channel instrument and the f/9 secondary mirror were removed on June 18th and the telescope was parked horizon pointing and covered with a tarp. Kappcon, Inc. then began the process of replacing the EPDM material used to seal the two MMTO shutter halves when closed. The horizontal seal section was replaced using a custom access platform borrowed from the LBT Observatory (as seen in the image here). The vertical seal section was replaced using a rented boom lift. This work was completed on June 26th, and after completing other maintenance tasks, the telescope was returned to normal nighttime operation on June 30th.
