After almost a year, I finally dared to collimate my Vixen VC200L astrograph and brought my Vixen Cassegrain back to life. I think it was definitely worth it. This evening marked the beginning of a longer series of crystal-clear nights.
Session Analysis
There is nothing particular to highlight about the session. The guiding that evening, as well as for the rest of the week, was rather below average—but okay.
The ambient temperature dropped from +1°C to -1°C during the session.
