The Bayer was very bad so I combined the real red, green and violet images for a composite.

The red filter image shows many dark markings some of which I marked that
agree with S. Ebisawa's map. I also annotated the color image showing clouds
over 4 Tharsis volcanoes.

I'm back to using my 12-inch Newt because of necessary changes being made to my NGT-18.
First Image of Mars in 2011 on August 04, shows large band of
dust clouds on Western (right) Limb.
In January 2011, I bought an 18-inch Newtonian, NGT-18 made by JMI in 1982. So I have a new-old scope. It seems to have excellent optics that were made by Galaxy Optics. Mars is only 4.4 seconds of arc in diameter and yet I was able to increase the EFL sufficiently to record recognizable surface detail. Good seeing. Jim Melka
