014/366: Summer Stars [Uncertain Principles]


Today was Rosh Hashanah– happy new year to those who celebrate it– meaning that both SteelyKid’s school and The Pip’s day care were closed. In an effort to maintain my sanity while keeping them entertained, I took them to the local science museum to rampage through hands-on exhibits. We also caught the planetarium show, because why not.

The show wasn’t really pitched right for my 7- and 3.8-year-olds, but it did make me wonder how the new camera would do at photographing the sky. And it’s pretty clear tonight, so here’s a shot of the sky more or less straight up at about 9pm Eastern:

Stars from the backyard at Chateau Steelypips.

This is a 30-second exposure (the longest setting available) with an 18mm lens (the wide-angle zoomed in all the way) and the ISO set to the maximum value of 12800. I cropped this down a bit because when I scaled the full field down to fit on the blog, you could barely see anything.

Just for kicks, here’s a 600×400 chunk from the full image, so you can see what you get without scaling the JPG:

A 600x400 piece of the full star field.

You can see that the individual stars are stretched out a bit by the long exposure, but not ridiculously so.

So, anyway, the new camera’s pretty good.

Bonus interesting note: The star field I cropped down for these is image 1001 with the new camera. So in two weeks, I’ve taken over a thousand photos (most of these are near-duplicates, because I keep it in the rapid shooting mode, because kids, and the shutter rate is faster than with the old camera). New toys are fun!
