A chronological archive of raw field notes, technical constraints, and operational insights gathered directly under the night sky during target acquisition.
M3 — Globular Cluster Acquisition Notes
Setup: Vixen VC200L + ASI 585MC AIRFirst engineering frames on Messier 3. Preliminary data analysis shows clipped highlights in the core stars, specifically indicating that the blue channel has saturated. This clipping was likely induced by either the high Gain setting (200) or an excessively long sub-frame exposure time for a dense stellar core. I will evaluate corrective measures—such as reducing individual exposure lengths or lowering the gain to optimize dynamic range—during the upcoming acquisition runs on alternative globular targets like M13 or M5.
