Coude
When using the coude focus, there a few hardware items that observers should be aware of.- There is a polar axis cover in the coude slit room. It is the observer's responsibility to remove the cover before observations begin and when they are completed at the end of the night.
- When observing at declinations greater than 55 degrees, the 5 mirror system must be used. It takes approximately 5 minutes to switch from the 3 mirror to the 5 mirror configuration.
