Couldn't find planetary CMOS with adapter
Chose to just use deep-sky CMOS on finderscope (since that's all we need)
Deep-sky CMOS connected to Icron USB Extender – connected to SharpCap without issue
No changes to focus needed to be made while reattaching
Dome shutters didn't open via DFMTCS > Telescope > MISC > Focus & Shutter Tab
When we used ASCOM Dome Control Panel, they worked.
WE DON'T KNOW WHY
We set auto-doming up
We assumed pointing was good from the last session
And it was
We slewed to NCG 188 and began taking a series of 1min-15min exposures
Remembered to set tracking rate to Sidereal Rate
We found a few good exposures
We tried comparing the captures to the STScI Digitized Sky Survey result, but this was hard.
We used AstroMetry.net to locate NCG 188 in our finderscope captures. This was much easier.
See results HERE.
Seems like Finderscope FoV with Deep-Sky CMOS is ~1.5deg x 1deg
We set the tracking rate to 13''/s and captured some images of NCG 188 trailing.
Put these on the Auto-guider webpage
We reset the tracking rate to 15.042''/s and began a series of exposures
We installed SAO DS9 to C:\ and added it to the system PATH
We wrote the AutoDoming wiki page
Closed up
Disconnect TheSky6
Telescope > Movement > Offset/Zenith > Set Zenith Position, then press "Apply" – this sets the scope's "Next Position" to the local Zenith.
Disable all tracking
Then press "Start Slew"
ASCOM Dome Control Panel > Close (Dome Shutters)
Disabled "AutoDome" switch
Disabled "DRIVES"
Disabled "MTR DRIVER CHASSIS"
Stored Deep-Sky CMOS
WE LEFT
ToDo
Notes
We figured out that the deep-sky CMOS cooler needs to be turned on via the SharpCap Camera Controls panel (right-hand side of window under "thermal controls")
Need to figure out what the home position of the dome is
