Description

The unthinkable has happened... Houston, TX has become a Bortle 1 site for astrophotography! Ok maybe I'm exaggerating a bit... But it was certainly darker in my neighborhood and across the greater Houston area this week courtesy of winter storm Uri. As I sat huddled by the fireplace for something like 36 hours with a good friend (my wife and his wife had taken the kids to the parents house which miraculously had power and running water) I couldn't help but think how awesome it would be to have electricity and to be imaging! Of course it would have been a little treacherous on my deck which was iced over. And my little generator would have had a tough time running my mount, laptop, dew heater, cell phone charger, and the coffee maker. And it would have been hard to find time between keeping the pool equipment from freezing and keeping the wild animals at bay (we like many others pulled our food out of the fridge/freezer and left it outside). But one can wonder, right? We finally regained power on Wednesday evening and after thawing out a couple pipes and checking the pool equipment, I was able to fire up the laptop today and do a little reprocessing on Andromeda. I've also included some pics of my yards and house from Monday morning. Before you northerners say "that's nothing!", remember our houses (and much less our pools) down here aren't built to withstand weather like this! 10 degrees F with a wind chill below 0 is cold! Thoughts and prayers for those still affected by this arctic blast.

P.S. I'm having a tough time relearning how to live with power... I still wear my headlamp everywhere I go and click it on every time I enter a dark room vs reaching for the light switch!
