During the two weeks leading up to my trip to Spain to observe the solar eclipse, we enjoyed a fantastic spell of clear and sunny weather.
While I was simultaneously imaging several objects with my second telescope during that week, I used my Baader APO to capture my first complete dataset with my ultra-narrowband filters over the course of three nights.
Unfortunately, the equipment caused a few issues during those three nights; otherwise, I would have been able to collect a little more integration time.
As a result of these problems, I have now purchased a second Stellavita.
