…-> Now plate solves but chart doesn't move when PiFinder moved
…. Smoother. BUT IMU tracking is L/R and Up/Down reversed!?
…explicitly as "F"
…ized_solved_dict()
Add support for Stellarium+ Mobile The critical command here is the ack command. Most of the additional commands aren't strictly necessary but speed up the connection process (otherwise Stellarium times out and moves on).
* Use J2000 as epoch when Stellarium is connected Stellarium seems to use J2000 as its epoch, while SkySafari uses JNOW by default. Technically we don't need to do position_of_radec etc. when J2000 is the input, but I thought this was a simpler change. Reference to Stellarium using J2000 - https://sourceforge.net/p/stellarium/discussion/278769/thread/fc15d042/ Update to Cedar was done here - smroid/cedar-server@f2f6b69 * Skip epoch conversion for Stellarium
…Alt and vice versa. Reverting change from commit (d364fef) seems to fix this.
…ils to integrator.py

There are some untested issues but I would like to get the review re-started again. Thanks! |

@TakKanekoGit This is a HUGE contribution and I know it took a big effort. Thank you so much, this will serve as a great foundation for future PiFinder work 🥇 |

Features:
Changes:
imu_pi.py: IMU data coordinates are no longer altered here depending on the PiFinder type. IMU outputs will be they are from the IMU. This is now done inimu_dead_reckoning.py.integrator.py: Substantial changes. Tracking is done in the equatorial coordinates rather than altaz coordinates. Use quaternion for the IMU dead-reckoning. Setssolver["Roll"]depending on the mount type for chart display.pointing_model\: The new classes and functions are grouped up here. It's possible that we could extend this in the future?requirements_dev.txt: Requires numpy.quaternion.This PR touches the core of the IMU functionality so it still needs to be tested thoroughly on all PiFinder types and also on altaz and EQ mounts.
Issues:
East showed up as moving to the right.
Sky test IMU orientations
