astrophotography

I decided to create a diary of sorts of my astrophotography toying, since it’s not exactly quality material yet, but might still be interesting reading. If you want to follow along, check it out

milkyway-stacking

Here’s something fun: around 10 years ago, my family went to Cape San Blas, FL for a week. I was just getting into photography – I had a Canon 20D, a wide angle lens, and no idea what I was doing. But the views of the Milky Way from the beach were spectacular. I tried taking some long exposures, but between the noise of my relatively old crop sensor and the heat, the results were riddled with noise and hot pixels. I gave up and never posted any of the shots I got that night.

Skip forward ten years, and here I am playing with astrophotography and learning all about image stacking. It occurred to me I might be able to salvage the original data. I had the 10 original raw images and I gave it a whirl. I was stunned by the results!

Before After

On the left is an example of an uncorrected frame I got that night. On the right, the result of stacking & cleaning up. Modern software is pretty cool.

  • Camera: Canon EOS 20D
  • Lens: EF-S 10-22mm (shot at 10mm)
  • ISO: 3200
  • Aperture: f/3.5
  • Shutter Speed: 30”
  • Total Exposures: 10
  • Software: DeepSkyStacker for stacking, darktable for levels correction & post-processing.

astrophotography

Somewhat a break from the normal fare here: I bought a telescope! I pointed it at the moon and some planets, which is probably about the extent of its capabilities.

Jupiter – and technically all four moons (though at this resolution admittedly they are hard to differentiate from pixel noise).

Blurry Saturn.

lightning

From the archives: lightning during a storm downtown – pre-Pinnacle tower and with the Encore under construction. And before I learned how to clean my camera sensor, clearly.

April, 2007.

These are as close as I get to selfies.

Paradise Park, Opening Night, March 2007

I didn’t realize the extent to which people considered Paradise Park a cultural cornerstone of downtown Nashville – which I suppose it is, at least in the 4AM corn dog territory.

So, rest in peace, Paradise Park – home to cheap pitchers, and, for a long time, this guy:

printer's alley

From this end it’s almost possible to see some of the old printer’s alley left. Though personally I still prefer the old painting over the reproduction.

fog

It was foggy out so I took photos of the fog and stuff with the fog.

solar eclipse

A few photos of the solar eclipse, taken from near Gallatin, TN (close to the center of the path).

Money shot of the diamond ring:

Nice closeup showing some of some prominences:

More pics (more than are necessary really) on my flickr site.

I also put together an animation of the eclipse, which I didn’t really plan, so it’s a bit choppy:
