SkySafari | How to use Field Rotation Angle

    Follow

    Originally from ticket #26651.

    I don’t understand the Field Rotation angle and its use in observing (I’m pretty new to all this) so I don’t know what I should set it at or if it has any use for me. I have an alt-az mount.

    I’d appreciate any assistance in these matters.

    Thanks.

    Gene,

    The field rotation angle is really only useful if you have a rectangular (camera) field of view indicator. It helps you to frame an image. For circular indicators it really serves no function.
