Spaces Occupied

• PHYS 401

• Control Room

• Dome

Goals

• Proof-of-Concept for spectro-polarimeter Bill Sparks designed

• Observe something 

Action Items/Things Done

• Reattached all port plates to instrument box

  • Had issue with a few screws on bottom plate

  • Need to ask Erik to machine new North plate to seal instrument box, absent the star guider

• Reattached CMOS Plate

• Pointed telescope using Deneb (Focus at ~2035)

• Used SharpCap software on data computer to perform fine-adjustments

  • Used Tools > Focus Assistant > FWHM Measurement

• Confirmed pointing by slewing to Vega

• Moved to Saturn, recorded cool wiggles and moons (Titan, Enceladus, Helene, Rhea, Mimas)

• Slewed back to Deneb so that we could swap CMOS for Spectro-Polarimeter

• Slewed to Jupiter to test spectro-polarimeter (Focus ~2609)

  • Looked at Europa, but could also see Ganymede 

• Slewed to AM Herc (circularly polarized)

• Slewed to HD 23512 (linearly polarized)

• Cleaned Up

Notes

• SharpCap has A LOT of cool features we should explore

• Slaving DFM TCS to Data Computer could allow for automatic focus of scope and gain control of CMOS

• Build informative header files (to include stepper motor/telescope info)

• Find a better way to secure CMOS to plate
