- Followed opening procedure
- Connected cameras to scope
- planetary on axis
- deep sky on finderscope
- pointing at Capella
- Attempting to focus
- Attempted to measure Seeing via FWHM reported by SharpCap in pixels.
- Calculated 25'' for planetary camera (13.8 pix average for best FWHM measure)
- 2.4um/pix → 6500 mm focus for DFM Scope → pixScale/focalLength*206.265
- Couldn't accurately determine focal length of finderscope, so couldn't figure angular resolution of detector easily
- It was very clear that the tracking is off with on-axis camera
- Moved to ZTF, similar to last time: just fuzzy
- Took some saves with finderscope (darn: saved as PNGs)
- Onkar fixed this. Roy only made it worse
- onkar update: pixel resolution is still off idk how to fix it but still usable
- Moved to a variety of blazar objects:
- m87 - on Eastern horizon. Will rise through haze after clouds arrive
- 3c 273 - in virgo, below the horizon
- ngc 1275 - Sparse
- ngc 3862 - east, lots of light pollution in that direction
- m77 - Galaxy, tried to get good exposures
- unsuccessful, not sure if I was looking at it
- m42 - great orion nebula, beautiful as always
- ngc 1432 - pleiades maia nebula, purdy
- SHUTTING DOWN - Shutters incident
- Shutters no shut
- Onkar pressed "close shutters" on DFM TCS, activity message said "OPENING SHUTTERS"
- Matt visually confirmed, shutters no shut
- Onkar scratched head and had the bright idea to click "open shutters"
- since shutters already open, shutters no open more
- Onkar let it run until it stopped on its own, clicked "close shutters" again
- same issue as before, shutters no shut, same activity message on DFM, very sad
- Onkar went upstairs to shutter panel, flipped switch from "remote" to "manual"
- I forgot if its actually called manual but the one that's not remote, ykwim
- anyway
- after flipping switch, closed shutters via switches in shutter panel
- after shutters closed, onkar put shutter switches back to neutral and the command switch from "manual" back to "remote"
- will test if shutters open and close via DFM software at next working session
ToDo
- Second security camera needs to be installed near dome encoder.
- Get static IP for network switch
- Roy: Bring side table in for control room
