Date: 20230110 1300-

Attendance: Connor, Nathan, Matt, Gabriel, Eileen, Roy, Erik

Spaces Occupied: 401, 433C, 306A, Machine Shop

Goals

1. Install GAM-lite

2. Attach small CMOS

3. Find CMOSs (3x Small, 2x Large)

4. Attach Autoguider

Log

1. Eileen/Roy met at 1300.

2. Met in 306A at 1330. Erik delivered GAM-lite

3. Moved to 401/433C.

4. Prepped DFM Scope for GAM-lite install

   1. Found screws

   2. Ladders

   3. Jack

5. Held up by misalignment between jack plate and North

6. Could not attach small CMOS to GAM-lite

   1. Adapter plate screws wouldn't allow CMOS adapter to screw in

7. All met Erik in PHYS machine shop

   1. Gabriel talked to Erik about "SCREW NUT Part# Kerk BF6008N" found on page G32-081A

      1. Part seems to be hard to find.

      2. Gabriel 3D printed a replacement, but this didn't work

      3. Gabriel ended up doing something really weird. But it works. We may want to engage with Erik to lathe a new part per the specs in engineering manual

   2. Erik is going to:

      1. Finish FinderScope attachment for digital pointing

      2. Drill two additional holes in the GAM-lite bottom plate for attaching the old SBIG ST-4 CPU (autoguider)

      3. Also drill four new holes for the instrument rotator

8. Back in 401/433C.

   1. Erik completed the two additional holes for the old SBIG ST-4 CPU (autoguider)

   2. Under Roy's direction, Nathan and Gabriel forced the screws onto the bottom GAM-lite plate around the adapter plate.

   3. The small CMOS was attached the the bottom plate of the GAM-lite.

9. Gabriel demonstrated that if the DFM Scope is too far from zenith, engaging the "HALT MOTORS" button allows the DFM Scope to fall.

   1. We're not sure if this is a bug or a feature

   2. Probably Onkar's fault.

ToDo

1. Confirm GAM-lite plate places CMOS/attachment plate on-axis, w.r.t. focus: Need a clear sky

2. Determine focal range of DFM Scope to see if GAM lite is necessary (this would be good to know, but doesn't matter at this point)

3. Perform tracking sensitivity study with obs crew

4. FIND ALL THE CMOSs

Notes

1. Connor has C8 Laser Spotters
