Unfortunately over the central Mediterranean there is a local atmospheric cut-off low pressure that is deteriorating the visibility of the night sky during such an important period on Mars. The dust cloud seems now to have extended as far as Solis Lacus covering the entire half of this hemisphere as CM 279.8degrees.
Subtle detail can still be seen through the dust cloud, suggesting again that it is not very dense.
Getting a good focus during image acquisition is now becoming more difficult and a rather hit or miss thing.
The lack of good contrast is also leading to difficulty in proper image stacking and sharpening.
Unfortunately the weather forecast for Malta doesn't look good for the coming weeks.
