Hi All,

I am setting up my eyepieces in Stellarium's Ocular plug-in and was wondering if there was a spec sheet or similar for the various size pieces.

I have a Celestron Nexstar 130 with the following Celestron eyepieces:
1 x 25mm
1 x 15mm
1 x 9mm
1 x 6mm

The plugin asks for aFov (which I am taking a guess to mean apparent field of view, focal length (easy enough - 25, 15, 9 or 6) and field stop.

I whipped out Professor Google and there seems to be no ready specification sheet that I could find that is if use.

Any help would be greatly appreciated.

Pete
