Winter Canis Major Targets — Seestar S50 | Rockwood, TX | January 17, 2026

It is a good night for imaging at Starfront Observatories using my Seestar S50. My broader objective is to conduct systematic observations under Bortle 1 skies in Texas and compare those results with equivalent observations obtained under Bortle 7 skies near my home in Columbia, Missouri.

Tonight’s session will focus on Canis Major, imaging Thor’s Helmet (Sh2-298) and Caroline’s Cluster (Collinder 58), with the goal of evaluating nebular contrast, star-field resolution, and fine-detail recovery under dark-sky conditions.

At present, the Seestar S50 is the only instrument available to me at Starfront Observatories, which limits direct Bortle 1–to–Bortle 7 comparisons to this platform. In Columbia, however, my comparative imaging program will expand across multiple systems, including the Seestar S30, Seestar S50, Dwarf 3, Dwarf Mini, Celestron Origin, Unistellar Equinox 2, and my dedicated astrophotography rig. The goal is to evaluate relative performance across varying sky conditions, with particular emphasis on angular resolution, sensitivity, and fine-detail recovery.
