Focus is hard at night

Filed under: Uncategorized — larry @ 12:21 pm

I took this shot Thursday night up at Mauna Kea. I thought I was doing really well with the photography, but when I got home and imported the images, all of them were blurred. There wasn’t any wind, and I thought the scope was polar-aligned well enough, so for the moment I’m blaming this on manual focus.

The purple stuff is digital sensor noise, which I find kind of shockingly high. I took a “dark frame” (photos of similar exposure, but with the lens cap on) and can use Photoshop to subtract out the noise, but it’s not worth it for a fuzzy photo like this.
