Reading BME280 Sensor on Windows 11 via USB-I2C (CH341T_V3)
Python service running on Windows 11 that reads a BME280 sensor via USB-I2C (CH341T_V3), publishes temperature, humidity and pressure to Home Assistant over MQTT, and feeds SharpCap’s Observing Conditions in real time.

SharpCap EQMOD PPEC auto enable
SharpCap startup script that automatically enables PPEC in EQMOD at session start. An IronPython launcher (SharpCap) spawns a CPython worker that polls until the mount connects and sidereal tracking starts, then activates PPEC via ASCOM CommandString — no manual intervention required. Compatible with any EQMOD-driven mount (EQ6-R, EQ8-R, HEQ5…).

SharpCap Focus Secuencer
Thermal focus correction for SharpCap sequences — applies temperature-based focuser offset between exposures using a pre-calibrated TCF coefficient, keeping stars sharp throughout the night without interrupting guiding.
-
SharpCap Focus Temperature
Extracts autofocus results from SharpCap logs, removes outliers, fits a focus–temperature regression, and calculates the TCF for temperature compensation.
