Lightning from Kitt Peak

Saturday night featured some impressive lightning storms in the distance as I was preparing to observe from Kitt Peak.  Most of the lightning storms were probably at least 30 miles away.  Here are a few of my favorite shots from the evening.
Here is the storm around sunset when it was south of Tucson.  You can see precipitation and there was plenty of lightning.  Lightning is hard to capture with short daytime exposures and the only bolt I got before sunset is blurred by camera motion.....  This image was taken with my 18-250mm telephoto at 18mm focal length on my Canon 70D with an exposure of 1/15 seconds at f/8, ISO 100.

These 2 shots are looking southeast past the McMath Solar Telescope with the Spacewatch 1.8-meter telescope dome at the far right.  The images were taken with my 18-250mm lens at 18mm focal length with an exposure of 15 seconds at f/5.6, ISO 1600.

This final image is looking back towards Tucson where the storm moved over the western half of the city.  This bolt is hitting near Ajo Road just right (southeast) of Cat Mountain and there is lots of rain falling left (north) of the lightning strike.  This image was taken with my 18-250mm lens at 87mm focal length and an exposure of 25 seconds at f/8, ISO 1600.

Tonights Moon

I set up my Celestron 8 inch EdgeHD today on the off chance I might be able to see the Falcon 9 Jason 3 launch from Vandenberg this morning.  I didn't (except for the live feed on the web) but I did test out my 0.7x focal reducer on the Sun (with solar filter) and then after the Moon rose a bit later, I slewed over to take a look at it.  The first photo below is from about sunset while the 2nd one was taken earlier in the afternoon with the image in bright blue daylight.

This image was taken with an 8 inch f/10 EdgeHD telescope with my Canon 70D with an exposure of 1/200 seconds at ISO 400.  I applied an unsharp mask to sharpen the image a bit. 
This image was taken earlier in the day in bright blue skies with the same setup and an exposure of 1/1600 seconds at ISO 400 with similar use of an unsharp mask.  Seeing was less steady.

Bandon LIghthouse

In the Summer of 2014, we visited Oregon, doing volcanoes southbound and then up the coast visiting lighthouses.  This is the Bandon Lighthouse on the south side of the Coquille River.  I was born across the river in Bandon and spent the first 8 years of my life enjoying this lighthouse and the beach south of the South Jetty across the river here.  This image was taken with my Canon 20D using my Sigma 18-250mm zoom.

Here is the same image but converted to black and white.

Kitt Peak covered in Snow and clouds.

Not a good night for observing on Kitt Peak.  The Steward Observatory 90 inch Bok Telescope is just visible through the summit level clouds as the Sun sets on the western horizon.  This image was taken with my Galaxy Note 4 camera on Friday night, January 8th.

Morning twilight from the 90 inch.

We were observing at the Steward Observatory 90 inch Bok Telescope last week and this was the view we had of the morning twilight sky.  On the left is the dome of the telescope and you can see the lights of Tucson on the left near the dome in the distance.  In the sky, the brightest "stars" roughly in line is Jupiter, Mars, Rigel and Venus bottom to top (Venus is the brightest).  On the right is the McMath Solar Telescope.  This image was taken with my Canon 70D and 10mm fisheye lens with an exposure of 13 seconds at f/4, ISO 400.

This is the view south from the Bok Walk on the south side of the 90 inch dome.  High overhead is the slightly brighter than last quarter moon with Orion to its left.  The Spacewatch 36 inch dome is the most prominent dome below the Moon.  This image was taken with my 10mm fisheye lens on my 70D with an exposure of 13 seconds at f/4, ISO 400.

Colorful sunset

Here are two views of last nights sunset from our backyard, both taken with my Galaxy Note 4's camera with different white balances.  The shadows on the upper clouds caught my attention first and you can see them change over the 5 minutes or so between the two shots.  You can also see virga from the clouds below.  I am almost spoiled by the extra processing that my cell phone camera can do even before the images are stored compared to what I might need to do after the shot with my "real camera".  According to the image information, the exposures were f/2.2, 1/121 seconds, 4.8mm focal length and ISO 40 for the first image and f/2.2, 1/30 seconds, 4.8mm focal length and ISO 64 for the 2nd exposure.  I think the first was in auto white balance and both used HDR mode for the exposure.

Lightning over Tucson

I watched a nice lightning storm over the Tucson area tonight after sunset.  Lightning appeared over Oro Valley and Mount Lemmon while it was mostly clear overhead on Kitt Peak.

 This image is looking over Oro Valley, in the general direction of Biosphere 2.  Twilight was still heavy when I took this exposure.  The exposure is 2 second at f/4, ISO 1600 with my 70-200mm f/2.8L lens at 70mm focal length.

Looking over Tucson with the Tucson Mountains in the foreground and the Catalina mountains behind them.  A few strokes of lightning hit near the summit of Mount Lemmon with lots of other activity overhead.  This image was a 30 second exposure at f/8, ISO 800 with my 70-200mm f/2.8L lens at 100mm focal length.
