Mars as it gets closer

That is a very nice image Micahel, though somewhat smaller than I would have thought you could achieve ith such a large scope!

By the way, do you notice the slight 'bubble' out of the edge of the atmosphere at the "6:30" position? It looks to be somehow related to the white bubble Dave Gradwell found in his (same position almost, have a look here ). What do you think?

Seanie.

I thought it looked quite big to be honest.
Anyway, I not fully convinced that I'm seeing the white hue in this image.

Seánie,

I would ques that that is what is left of the South polar cap. The cloud that Dave Gardwell was refering to was somewhere else on the southern hemisphere. I do not have a detailed enough map to know where

Solis Lacus

is so I could not comment.

Anyone know if there is a detailed enough Mars map online?

smaller than I would have thought

My Dob has a focal length of just 1280mm where most of the images online use STC's with much longer focal lengths. DaveG's focal lenght is over 3000mm and the addition of the barlow at least doubles it.

So size does matter

Not a white hue, just the mark, or spot, is what I can see...

Sshhh... not so loud! My instrument is only 700mm long!



P.S., its my ETX-70!!

Michael,
I also was taking images of Mars that night and by contrasting with your image, it might have been an hour or 2 earlier then me ?!?.
Its very interesting to see the same features rotated, its like seeing over the edge of the planet.
Keep an eye on the bright (near vertical) line seperating the dark areas in the lower half of the image while examining the 2 images, it gives you a referance point.

To be honest, I wasn't even going to post this, except that it makes the rotation point.
There was very high level cloud, I could not even see the plough, all I could see in the entire sky was a faint mars with a red hazy glow around it. The seeing wasn't bad but the cloud scattered all the detail.
