mars last march

This was taken after the glorious opposition, so Mars had already shrunk to 1/225th the width of the full moon by this time. To put this size into perspective, hold your thumb out at arms length. Mars as seen here is approximately 1/900th the width of your thumb.

I took this with an 8" refractor and a Phillips webcam.

Beautiful!

I've told my husband about you. "Deathcow, this guy on VS, is a ruddy-haired fella, beard, funny as hell, loves/had hound dogs and has a backyard planetarium he built himself in ALASKA" He was impressed and envious

He's been trying to get me to move to Alaska for YEARS. I told him not unless he built me a 30 foot geodesic greenhouse there. I'm safe

That wobble is just atmospheric distortion?

I can't believe what I'm seeing. Amazing. I think I see canals!

Yes it's the movement of the atmosphere. Notice you can still see features much finer than the amount of movement that is going on.

Yeah, I think I see the ice caps winking in and out.

I see the northern ice cap pretty stead here at ~2o clock, I cannot see southern polar stuff at all. I see a dark land edging out from under the northern cap. I see Syrtis Major steady with occasional "crystalization" of features wanting to come through the seeing. I see hints of dark patches of land in the broad orange expanse coming and going, especially close to the tip of Syrtis Major and closer to the ice cap. I pick up on the Hellas basin once in a while and I get a feel for the dark "arc" which reaches up around hellas.

I love Mars and observing it. I wish I would have had the same setup for recording films like this when Mars was 2.5x wider (this mars is about 50 square arcseconds... 2 years ago it got to 320 square arcseconds... imagine the detail I'd be grabbing...)

Now to give you some perspective of size, this Mars you see is ~50 square arcseconds, Jupiter can become almost 1600 square arcseconds in size. Jupiter will be in my skies in 2011 - 2012 big time.

Pretty easy to see where Percival Lowell got his crazy ideas, eh?

yes for sure, especially once convinced of it, then you no longer watch for dark things, you WATCH for CANALS
