Mars is shrinking fast, now at an angular diameter of 11". The blue color
channel in this RGB image picked up large clouds above the globe. I shot with
a relatively small image scale with the 10-inch and 2.5x Barlow, and up-sampled
the image by a factor of two.

Here is Venus, which has grown to 31", shot through a UVenus filter. Only a
large, lighter patch near the center is apparent in the image. I was surprised
to see that this feature was also noticeable visually before the camera went
into the focuser. As Venus grows, it's phase shrinks, so cloud-watching will
be over in a few weeks.
