SVN commit 920679 by asimha:

Applying Alexey Khudiakov's patch, making usability improvements to
the FOV Editor:

+ Telescope eyepiece apparent fields are now measured in Degrees
  instead of arcminutes.

+ Make the Eyepiece tab default

Thanks Alexey!

Code quality improvements and a (rather critical) bugfix.

+ Removing old commented code that is no longer required

+ DeepStarComponent now uses functions used to find out star sizes and
  the limiting magnitude from StarComponent. This not only reduces
  code duplication but removes a critical bug where the star sizes
  were not in proportion with their magnitude, but would vary from
  catalog to catalog.

[X-POST] Question about Coma Diameters of Comets

Hi

Could someone provide me with an approximate relation that gives an
estimate for the diameter of a comet's coma?

I found a relation that gives me the nuclear diameter here:
http://articles.adsabs.harvard.edu/full/gif/1978BAICz..29..103K/0000113.000.html

I need this to calculate comet angular diameters in KStars, to make
the display more realistic.

Cartes du Ciel does display estimated angular diameters, but the
source code reads 'Personal formula based on experience'. I wanted to
know if I could find a more concrete formula.

Any other inputs - like estimates for dust tail / ion tail lengths etc
will be appreciated.

Thanks.

Regards
Akarsh

Thanks a million, Jeamy. I'll implement this sometime soon.

I've downloaded the MPCreader generated comets.dat from your website,
and I'll do all the checks (magnitude, coma diameter, position)
shortly.
