Mars observation (4/11)

Around 3:30-4:10am, LXD55 unaligned, Sky90.

Captured 3 clips using color toucam, the middle one has some parts covered by cloud, 5x Powermate alone. Tried to stack 2x on 5x, but the seeing does not support, a blur patch of light, featureless, so didn't capture any of them.

Sky90 was capable enough to deliver that image scale, since nearly no chromatic abberation can be seen.

Finally, used 13mm Nagler + 5x to observe, can see the poor seeing easily. Also, tried to use binoviewer, can reach focus, but can see some strange reflection. I remember that I saw it before... still dunno why. Put the 2x in, and it's even worse. Both can reach focus with the 2x SCT corrector before the diagonal.
