I use a program called Twilight on android, which is set to automatically remove blue/green colours after 7:30pm and re-introduce them at 6:30am.
A great little app but it keeps crashing from time to time.. not the best thing to be blasted with high brightness blue light when checking a forum out just before putting the phone on the bedside table I can tell you!
Well with massive rain and no observing have finished me Denver chair.
Has foot rest and head rest, not bad for someone who failed wood work!
Cost $5 for screws and $12 for varnish yet to do.
What a great wet-weather project, and looks impressive. Symbols are a nice touch
I'm hoping to head down to Kyogle soon and take in some night skies as I have family who live at Green Pigeon.
