🚀 New

* [17](https://github.com/sdss/HAL/pull/17) Use 730 second exposure times for bright designs.

🏷️ Changed

* Increase slew timeout to 300 seconds.

✨ Improved

* Retry lamps at LCO to deal with cases when `TCS_FF` fails.
* Use `/screen` flag for LCO slews.

✨ Improved

* Reset cherno offsets when goto-field is called.

🏷️ Changed

* LCO: added a 25 second delay before acquisition / guiding to give observers time to remove the FFS.

✨ Improved

* Added the option to define goto-field calibration slew offsets.

🔧 Fixed

* Add 3 second delay before running `goto-field` cleanup at LCO to prevent lamps being switched on/off too fast.
