Dear observers, we had a clear night again here in Germany. This favourable apparition is fascinating! I never saw solis lacus such clearly.

This time I tried to reproduce colors and contrast as accurate as possible. I always saw the northern hemisphere more yellowish with only a hint of orange. The southern hemisphere was more orange. Of course, the "Red planet" is red nowhere.

 

At other apparitions the SPC seemed to be blue for me. Not this time: It was always pure white. I knew that was a contrast effect, but it is great to see that it can be different.

 

I most liked solis lacus, the eye of Mars. I never saw it so clearly like a real eye.

 

Instrument was my 12 cm refractor, magnification between 180x and 225x. Most features was seen without filter, but the da maria were more clear with orange.

 

Comments:

- solis lacus striking (in orange filter, missing at the sketch)

- such small only in Orion Mars filter [SPC]

- with green filter more clear [bright area at the f side]

Uwe,

That is exactly how I see it at the eyepiece as well. My past sketches have not reflected this -  so this week I spent some time indoors trying to get the color just right.

 

Your sketch and colors are accurate and represent what is seen at the eyepiece.

 

Keep up the great work!

Trent
