![]() ![]() Scale = 206.3 * pixel size / focal length We can calculate pixel scale for given setup with the formula below: 10um pixel camera will give exactly the same result as 5um camera used with 0.5x focal reducer. Fast instruments their own drawbacks and are expensive, but this is out of scope of this entry.īut, but, doesn’t “when you attach 10um pixel camera to 100/1000 telescope you will get the same result as with 5um camera to 100/500 telescope” sound like focal reducer? Sure it does. But more important is the fact, that for fast instruments you can use smaller sensors to achieve larger field of view. Fast instruments are smaller and lightweight, so more handy and require also smaller mount. In real life (especially among amateurs) people tend to use fast instruments due to few reasons. aperture is the most important factor, focal ratio is secondary value.And this result will be much better than for 5um camera and 50/500 telescope when you attach 10um pixel camera to 100/1000 telescope you will get the same result as with 5um camera to 100/500 telescope.larger aperture setup will give better quality images (in terms of SNR).There are few thoughts that come from this example: Large/small aperture effect at the same pixel scale And since the pixel scale is the same in both setups, so each pixel from first setup will get four times more photons, and the image it will provide will be much better quality – signal to noise ratio (SNR) will be better. 100mm aperture telescope will collect four times more photons than 50mm aperture telescope, because it has four times larger surface that collects light. In astronomy aperture rules, that is why telescopes are first of all large, not fast. But these setups differ with fundamental parameter – with aperture. Do they also provide the same quality images? One could say yes. second camera with 5×5 um pixels with telescope 50 mm aperture and 500 mm focal length – so 50/500īoth setups have the same focal ratio and also provide images with the same 1Mpx resolution and the same pixel scale about 2″/px.first sensor with 10×10 um pixels with telescope 100 mm aperture and 1000 mm focal length – so 100/1000.At both setups we have camera with 1Mpx resolution (1000x1000px): At start let’s consider two setups with the same pixel scale. I also do not deal with optics aberrations here. Two setupsįor this article’s scope, I assume the sensors I describe have the same noises and the same sensitivity (quantum efficiency).
