Calculate Image Scale & Field of View
« on: 2019 November 08 08:31:25 »
I'm brand new to pixinsight.  I've been going through the tutorials.  But I've run across a question about the Calculate Image Scale and Field of View.  The program asks for the pixel size in microns, the width in pixels, and the length in pixels.  The problem is that I have a Canon T4i.  The Canon specs are not listed this way.  Canon shows all their specs in mm.  Can someone help me get the correct specs for way pixinsight wants them?  Thanks

Hello Viren,

See this link:

I think you will find the data you need.

Best regards,

Enzo.

Thanks Enzo,

That's the first site I looked at.  It doesn't tell me the length or width in pixels.  It does list the pixel area, but I need the pixel size.

Can you help?

pixel pitch is the same as the pixel size. as a sanity check, 4.29um**2 is 18.4um^2, so that means each pixel is 4.29um on a side.
