Whenever I have come into large sums of money in my life, I always put half of it aside to spend on fast cars and the pursuit of loose women.
I put aside the other half to spend frivolously.

Quote:Stan, your drawings do not show the same curvature of the features as they are in the Keck pictures. In most of your sketches you show the 'bands' to be nearly straight lines and never even remotely as curved as they are in reality. This, plus your continiung failure to show the limb darkening in your sketches, reduces greatly the credibility of your efforts.Dave

"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
Quote:And here's a screen grab of the Keck IR shot which shows the amount of curvature that should be there assuming the bands/zones Stan is drawing are parallel to the equator of Uranus which they pretty much must be...
Quote:The main parameter is not the diameter but the contrast transfer ratio for capturing details of low contrasts (probably 1-2% level on the planet, not at the eyepiece).
A new time a 16" will not involve 2 times better the contrast level at the eyepiece with comparison of a 8".
Until your scopes at not characterised (PTV, RMS, etc... for getting a strehl not by a zygo report) this is useless.
