- Fixing guide drift: a PHD2 log deep-dive Two weeks of RMS oscillation, one bad RA cable contact, and a lot of wasted subs. How I found it and what I changed.
- M31: two hours from Bortle 7 Andromeda with the L-eXtreme narrowband filter. 96 × 75s subs, stacked in Siril. What works, what I'd change next time.
- First light: Samyang 135mm on the ASI294MC Milky Way core on a warm August night. The coma performance wide open surprised me. Notes on collimation, focus, and the first real result.
