Astrometric Calibrations

Attendance Gabriel, Roy, Olivia, Sophia, Em, Luna

Date & Time 11/09/2022, 1730-2130

Spaces Occupied

Goals

1. TCP/IP Connection Investigation

2. Point Scope

3. Astrometric calibration with M67 or NGC188

   1. Need sidereal tracking, not solar

   2. So point on high star

   3. Use https://archive.stsci.edu/cgi-bin/dss_form to find images

4. Write up tracking vs (auto)guiding

5. Write wiki for general telescope use

Log

1. When opening mirror doors, South mirror door was super slow again

2. We figured out how to send simple (setting set rate) commands over TCP/IP from DC-TCS

3. Pointed with Deneb, couldn't be sure due to what might have been reflections or dimmer stars

4. Moved to Jupiter, moved around a lot (~10 min). Reflections down light baffle complicated pointing.

5. Finally found Jupiter, and used this to point.

6. Then more finely adjusted pointing with Scheat in Pegasus.

   1. Best FWHM was 13.7, but not constant

7. Moved to Saturn.

8. All objects were very fuzzy. Not a good night for seeing.

9. Then went to NGC 188 in northern sky.

   1. Took 2x 300s exposures

   2. Took 2x 450s exposures

   3. Stored in "D:\SharpCap Captures\2022-11-09"

10. Closed everything down.

11. YEP

Other notes

Still need to write up closing/opening procedures

Need to connect Sophia with Don Engel

Need to connect Olivia with CSST folks (perhaps via Don Engel)
