Description

I have been a little scared of collimation, as the 8" Classical Cassegrain is my first reflector. I collimated the primary mirror with a defocused on-axis star and tried to center the central obstruction shadow. This turned out to be less terrifying than I had imagined. I evaluated a shot of the defocused star using Skywave, which confirmed that I had improved the coma beyond what the trial version will evaluate. I now have to decide whether to pay for a skywave model or to align the secondary "by eye."
