I compared my observations of the variable V603 Aql with an observer in Spain, who imaged with the same camera (STT-8300M with a JC-V photometric filter), but a larger scope—10” as a I recall, versus my 4” refractor. The AAVSO alert (743) called for a fast cadence since this star shows high frequency oscillations. At magnitude 11.5 I had to image for 60sec with 80sec between saves, compared to his cadence of 20sec. Sure enough he caught a lot more detail than me (black, versus red for my observations).
I’ve been locked in analysis paralysis regarding the next scope, trying to anticipate features that would limit its performance for my applications. There are just too many variables: local weather, the mount, the camera, and the details of the design and construction of the
