camera FOV in Cartes du Ciel

[alacant]

Hi everyone

I put my camera into CDC and can see the rectangle it gives. It seems that the default orientetion is with the camera's long axis at right angles to the telescope focuser knobs, what I'd call portrait. Is there any method for rotating the CDC rectangle to be able to frame a little better?

TIA

Go to "setup" then "display", There are various tabs across the top, go to the finder rectangle (ccd) and change the number in the rotation column.

.......... or you can do it 'on the fly' by pressing SHIFT S and using the keyboard arrow keys to rotate to any angle you want. The angle you have selected will be shown on the reticle's base.

Thanks. Can anyone confirm my camera orientation theory corresponding to 0.0º in CDC? I think it's with the camera at 90º to the focussing knobs.

Assuming an equatorial mount and a refractor then 0.0º (i.e. with the long edge of the sensor aligned with the RA axis)  then the camera will be at 90º to the focussing knobs.

It depends on the order that you enter the sensor dimensions into CDC. I.e. bigger or smaller first. CDC does not know whether your camera is landscape or portrait ?
