Goals
Find missing ZTF/M42 data from 20230126
Setup GoogleDrive Sync
Take Flat, Dark, and Bias frames
Test configuring PHD2on the Control Computer and use it via the finderscope
Log
Turned DC on (Why does this turn off?)
Starting Up Scope
Control Computer(CC): Started DFM TCS, ASCOM Dome Control Panel, TheSky6
Front Panel: Enabled MTR Driver Chassis, Drives
DC: Opened Blue Iris
CC: Dome Control > Connect; Then Open
CC: TCS > Telescope > Initialization > Apply Windows Date & Time; Sync
CC: TS6 > Telescope > Link > Establish
Cameras
Collected Deep-Sky camera and planetary camera from shelves with adpaters
Connected Deep-Sky Camera to Finderscope; powered (still on?); connected to Icron extender with long USB-3.0/B
Connected Deep-Sky Camera to On-Axis port; connected to Icron extender with shorter USB-3.0/B
DC: SharpCap > Cameras > ZWO ASI 2600MM Pro (Deep-Sky)
Finderscope camera is working
DC: SharpCap > Cameras > ZWO ASI 178MM (Planetary)
On-Axis camera is working
Enabled Auto-Doming
CC: Enabled Dome Control > "Slave Dome to Scope"
Front Panel: Enabled AutoDome and Dome Track Switch
DATA FINDING
GON Captures are in "D:\SharpCap Captures\2023-01-26\Capture\20_49_30"
ZTF Captures are in "D:\SharpCap Captures\2023-01-26\Capture\21_32_14"
DATA SYNCING
Downloaded and installed Google Drive Setup from https://www.google.com/drive/download/
Installed on Director user profile
Used Roy's credentials to log in
Setup Sync between " "D:\SharpCap Captures\" and "UMBC Observatory > Observations > Spring2022 > SharpCap Captures"
SharpCap File Save Settings
Toward top-right of the SharpCap window, there is "Capture Profiles"
You can load, save, manage different save profiles, specifying file type and some other fields.
ALSO. On the bottom-right of the SharpCap window, there is a Scope Controls frame with a notes section. This populates a Notes field in the save profile, it's not clear where this ends up – doesn't seem like it gets to the FITS header ...
Open Mirror Doors
CC: TCS > Telescope > Misc > "Switches/Mirror door"s tab
We confirmed that all four mirror doors opened correctly
Weirdness with Lower Dome Shutter
We noticed that the lower shutter didn't open all the way from 2.d.
Fix: Asked them to open again, and the lower shutter opened all the way
Downloaded/Installed PHD2 on Control Computer
Needed Connection from Finderscope Cam to Control Computer
Disconnected Finderscope Cam from Data Computer
Attempted to use Finderscope cam with LBD2 and Control Computer; No result, but it worked fine with Data Computer
Installed ASI Camera Drivers on Control Computer
Still no success connecting cameras to Control Computer
Tried connecting Finderscope Cam to Control Computer using front panel USB ports with LBD1 with no success
Connected Finderscope Cam to Control Computer front panel with the USB Extender Box
Successfully connected Planetary Cam with LBD1 to Data Computer
Continued working with PHD2
Camera Selected: "ZWO ASI Camera"
Telescope Focal Length entered: 952 mm
Put corkboard sheet thing over Finderscope to build dark library in PHD2
Took dark library with "Min Exposure Time" set to 1.0 s, "Max Exposure Time" set to 6.0 s, and "Frames to take for each exposure time" set to 5. The bubble for "Create entirely new dark library" was also selected
Uncovered Finderscope
Stopped with PHD2 to try MaxIm DL
CMOS not listed in Camera menu
Installed ZWO drivers for ASCOM and ASCOM Platform on Control Computer
Went back into MaxIm DL and connected the camera
Navigated to the Expose Tab of Camera Control
Took a dark frame (Covering the Finderscope with the corkboard sheet again)
MaxIm DL couln't connect to mount with the drivers
Went back AGAIN to PHD2
Got everything connected and got images on-screen, but couldn't guide because the software crashed early on
Couldn't replicate what allowed us to get it working in the first place (software not working as expected)
Decided it was best to stop for the night and do more research before trying again
Stowed telescope at Zenith
Closed mirror doors
Closed dome shutters
Put away cameras
Disengaged switches on front panel
Note: For thermalizing the dome, the hatch must be closed. The hatch being open seems to heat up the dome according to Gabriel's small thermometer. Reported weather temperature outside was 0C while inside the dome the temperature only got down to 6C with the hatch closed. When we opened the hatch the temp went up to 10.5C. The thermometer was positioned on the telescope pedestal.
ToDo
Configure DC to remain on
Permanently allow BlueIris to run
Need extension cord to allow box fan to pull from roof access door
Need to buy another long USB-3.0/B cable @Onkar Rekhi / @Gabriel Koletsi , spec one of these out and post to "To Buy" discord channel
Notes
Finderscope camera port was not powered off
Finderscope Deep-Sky Camera image suffers from vignetting
Weather
Data
If using the telescope cameras, record the local and any remote location of collected data.
