Originally from ticket #7211.
Hi, I have asked this question a couple of times before over the years, without really any satisfactory solution - but the issue has come up for me again, so will ask again. I need to generate visualization graphics of the Sun (in particular) with a featureless surface that us *NOT* limb-darkened. This to (clearly) visualize transit and eclipse contact geometries WITHOUT approximations to limb-darkening. I am using a very simple -- ALL WHITE -- "surface model" - actually just an all white JPG imege file, I have added (imported) for the Sun, but when the Sun is displayed as a spatially resolved object SN Pro always renders that graphically as limb darkened - which is not what I want/need. See attached JPG. see no way to "turn that off" with the options availbale in the Options/Solar System/Planets-Moon dialog. Using "Options/White Sky" does not help. A couple of years ago some suggestions were made
to use screen snapshots, but that did not solve this issue. I actually want/need to use this to verify some upcoming observation planning and if there is any solution to this you can suggest that would be most helpful.

I read that linked post before I asked for help. This does not work for me and is not
a solution that works. My question stands. I will ask more specifically as I still do not know the answer.
(1) Is it possible in SN Pro to suppress the display of the Sun from being limd darkened?
YES or NO ? (Note I am using a pure white image for the Sun's surface - SN Pro lim barkens it
(2) If the answer to (1) is YES then HOW? Is there some option in some menu/dialog I do not see?
(3) If the answer is no - would you PLEASE consider doing this in a future release?
YES or NO?
(Notes: [a] In much older version of SN Pro, back in the MAc OS 9 days this was not an issue
[b] the program must be actively doing this unwanted graphic computation as a "default"
my guess is it would be easy to "turn it off" if you provided a hook/mechanism to do that
through the solar system options dialog where other options for annotations are set.
Thanks in advance for your replies to question 1 - 3.
