Log
* 0128-3C 273 was not viable, too low * 0130-Clouds rolled in * 0142- Slewed to Vega to confirm that there was no pointing error, cloud cover making it difficult to see high magnitude targets
ToDo
Notes
Astropol is implementing a technique to ensure that the detector is “north up” - to decrease the amount of drift that occurs during long exposures. If not “north up”, the RA tracking movements can “leak” into the DEC, and move the target vertically on during captures.
