A quick update on the trip to McDonald Observatory in Texas (more to come later):
Purpose of the trip
To install the HPF thermal enclosure and start subsequent temperature monitoring (using Paul's awesome LakeShore - Raspberry Pi setup). The HPF - which needs to be extremely stable temperature-wise - will sit inside this enclosure which will buffer the temperature variations in the basement of the Hobby-Eberly telescope dome. We are hoping to achieve a factor of 10ish buffer; we can deal with a facor of 5ish.
Skies and weather
Excuisite, but cold, (~ -5 Celsius at night). Pictures below:
The 107-inch telescope
Or 2.7m in real units!
Can you spot Andromeda?
