I am wondering if someone could check my numbers here to see if I am on the right track.

I am using a Canon 5D Mark3. And scope is a 120 mm Skywatcher… refractor.

Here is the numbers I have and am using in SGP for plate solving…:

Pixel dimension -5760 x 3840

Pixels 23.4

Pixel size 6.25 um

I took those numbers and ran it through framing and mosaic in SGP to produce a scale number.

Here is how I did that:

I entered the following in Framing and Mosaic:

Pixel size 6.25 um,

Focal length 840mm

Calculated Scale of 1.535

That is where I am . I entered this Scale number in Scale for the camera. and Pixels 5760 and 3840 for the other areas. Nothing more to enter.

So with that… could someone tell me if these numbers are wrong? And if so how.

Plate solving by the way does not work with these numbers…
