Bug Description

Dear Stellarium developers,

I have entered these data:

  name: Bresser Everest 8x42
  Focal length: 8,0
  Field stop 0,00
  Checkmark in Binoculars check box

With these data the plugin shows:

  Ocular #2: Bresser Everest 8x42
  Magnification 8x
  Exit pupil 12.62 mm
  FOV: 8.1°

The exit pupil is wrong, magnification and FOV are okay.

 The error also occurs with
    7x50 bino (exit pupil 14.43 mm)
    4x22 bino (exit pupil 25.25 mm)

Maybe I entered the data wrong, maybe there is a bug. I thought I'd report it.

Thank you for Stellarium and the Oculars plugin. Stellarium is my favourite planetarium program.

best regards

Ruud, Leiden, the Netherlands

  Checkmark in Binoculars check box

Tentative fix for bug #1632145 has been comitted in trunk as revision 8735 (http://bazaar.launchpad.net/~stellarium/stellarium/trunk/revision/8735)

Let me hide exit pupil values for binoculars, because those devices doesn't have values of their apertures and we can't correct calculate exit pupil.

Possible way to resolve the problem - introduce field to entering of aperture for binoculars and use it for calculations.
