18mm vs 1340mm

That Titan camera has an absolutely tiny sensor so the crop factor is huge. The test isn't really fair unless you present them either as equivalent format focal lengths e.g. 35mm equiv. or you crop the 600D image until it's the same size as the Titan's sensor would give.

Yes it's a small sensor with 659x494 7.4µm pixels, I couldn't use the 383L+ at 3362x2504 5.4µm pixels as it has a minimum of exposure time of ~3 seconds - it saturates with just a

Cannon 600D has 5184x3456 with a pixel size of 4.3µm.

Here's a RAW crop at the Cannon 18mm native resolution:

@ K_D - I can't verify if it's 18mm but I just turned the cannon zoom to 18mm.. but that's all related to old school 35mm sensor sizes. In astro we refer to either the field of view as degrees, arc minutes or arc seconds as well as arc seconds per pixel.

There's the crop of the cannon 18mm at Titan resolution.

I think he's referring to the crop factor, 18mm is 29mm on a Canon crop SLR.
