Even now, image quality is most strongly affected by atmospheric seeing and without adaptive optics, you can't squeeze out a much larger resolution, no matter how good equipment you have. On the other hand, it'll be interesting to follow advances in adaptive optics over the years and how affordable they'll become to amateur guys. Check out Emily's blog on Uranus' equinox, there's a neat Keck montage showing just how AO improved in only 4 years. The next big quantum leap in amateur observing will surely come when (if?) AO becomes affordable. It's still best suited for infrared observations, though. -------------------- www.flickr.com/photos/ugordan

I can't even imagine what the next 10 years brings! I can, or at least try to do : next steps will include the diffusion of Orthogonal Transfer CCD (like the ones developed for PanStarrs project) which will reduce atmospheric blur through rapid pixels shift. And, on a longer period, perhaps the diffusion of simple, economic AO systems for evolved amateurs... -------------------- I always think before posting! - Marco -

He say: QUOTE May 28, 2006 Perfect conditions at last! I finally have a decent image of the GRS and the Red Oval BA! Both spots are moving closer now for a conjunction around mid-July. Note the hint of the whirlpool vortex in the ring of the oval BA. The NEB is very busy especially around the dark spot. And there is a weird feature on the NNTB at the CM where two dark barges are colliding? More images later as I am still processing about 15Gb of data!! -------------------- I always think before posting! - Marco -

closer and closer:

all images were taken from Christopher Go site.

Note also images reported in the other site dedicated to red spot, is incredible to see surface features on some galileian satellites from amateurs!

There was an exhibition meeting of the BAA in Cambridge last weekend, and the director of the Jupiter Section showed images that demonstrate that new spot is getting darker and darker red over time, coinciding with it speeding up - and also, the GRS is getting smaller and lighter ( over the past century or so ) suggesting an opposite trend.

Would be great to see this, even if time scale of the two events (GRS fading and RSJr reddening) seems completely different... -------------------- I always think before posting! - Marco -

Now almost touching!

Christopher Go comments is:"The GRS and Oval BA are very close now. From the looks of it both storms will just pass by! There is enough clearance between the two storms"
