…for hydrogen-alpha infrared. This mod will give it about 3.5 times the sensitivity to the glow of emission nebulas, and so enhance my ability to shoot astro photos.
In a fit of doing something that will be useful to almost no one, anywhere, I have created a calculator page that will tell you how many pixels a solar system planet, or an object of your own choosing, will consume in your final DSLR image.
In order to figure this out, you tell the calculator just a little bit about your camera, your lens system, and optionally, an object of particular interest to you.
If you actually use this thing, let me know in the comments. I suspect that I may, just possibly, get one comment. From me.
…and of course, if you find any bugs, let me know.
A lot of people seem to be quite confused about the idea of camera “reach.” This idea relates to how much variance in magnification you actually get between different camera bodies. I thought I’d take a few minutes to clear this up once and for all. I assure you the following information explains the issue correctly. Once you’ve read and understood this post, you’ll have a perfect understanding of reach.
For most 40D owners, the issue is simply: What has changed? I took a hard look at Canon’s specifications, press releases, and an early preview, and here’s the scoop:
Canon’s successor to the EOS40D is now a matter of public record.
The most important issue for me as an EOS40D owner is the degree of light sensitivity the new model camera offers; the 40D goes to ISO 1600 and will “push” to ISO 3200. The 50D goes to ISO 3200 and will “push” to ISO 12800, which is a huge improvement, particularly for wide-field astro photography which is an interest of mine, but also for low-light shooting in general. Higher ISO capabilities extend the range of situations any lens can be used in, a very welcome upgrade.
Among the sample images is one of a race car that was shot at ISO 1600; examining the dark areas of the shot, much less noise is evident than I would have expected based on my experience with the 40D. This is hugely encouraging.
The leak exposed a number of photos and diagrams that relate directly to the EOS50D; you can view those here, in a new flickr group I’ve created to support the camera and its users.
There exists a fairly vocal group of people who would tell us that a picture should be an exact representation of what you would see, as a human, had you only been there to see it. At least, as best as can be managed; that’s the goal. I find this to be only one very limited way to look at the world with tools of higher resolution and capability than my own. My own approach is… other.
These images show some views of my music studio, which is set up in an 11′x19′ open loft above our main living space. You get to it via a bridge from the master bedroom loft on the other side of the building. I’m into rock, blues, metal, and I dip a bit into almost everything else. I just like to play, frankly. Even music I don’t like to listen to is fun to play.
