That's what I had guessed. What you did made sense at the time.t00fri wrote:The automag scheme was implemented already very long ago. At that time we did not yet /compute/ the FoV in terms of the users distance from the screen and the window size (<-> resolution), as we do now. That's why automag is (still) normalized to a fixed FoV of 45 degrees rather than a monitor-dependent value.
I'm not sure I undertsand your question here. The user modifies the window size using the window manager or by toggling full screen mode.t00fri wrote:Apart from that, let me add that the FoV variation has an /exponentially large range/ via SHIFT+Mouse L, for example, while it is /in practice/ very small in terms of varying the window size. Why should we want to modify the latter anyway?
Perhaps instead:t00fri wrote:In fact, I don't really understand what exactly you are advocating. Do you want the flash output modified?
Like when pushing [ and ]:
Instead of
Auto magnitude limit at 45 degrees: 7.0
rather
Magnitude limit at magnification 1: 7.0
Auto magnitude limit at current magnification: 12.0
since users generally adjust the magnitude limit because they want to see more or fewer stars at the current magnification, and this would inform them what current (adjusted) magnitude limit is. But the flash message isn't my concern so much as the fact that I think the auto magnitude limit should be adjusted based on the magnification rather than the FoV.

When zooming you are /actually/ decreasing or increasing the FoV, but as you've pointed out, you're also /actually/ increasing or decreasing the magnification. And I'm not sure what the /default/ FoV means.
