- Oct 1, 2006Hi Wayne,
Unfortunately, that was the only time I had for imaging Jupiter this
year due to time constraints with my job. I hope to get better ones
next year. I don't have any "high-res" versions of this batch.
The images were optimized for a 1024 x 768 pixel screen size. They
will look bigger on that resolution or lower than say, a 1280 x
1024 screen or above. So some of it may be relative to the screen
resolution you are using if you are on a high-res screen. I also had
to shrink them down about another 30% due to so-so atmospheric seeing
the nights they were made, and the low altitude of Jupiter this
year. At native size, they just didn't look as good....too blurry
even after heavy processing in Registax, and some of it is no doubt
my own learning curve as well.
I eventually learned that the scope's optics are good enough to
handle 4X, so I've converted from 2.5X to 4X now, for a slightly
bigger-size image. I'm chomping at the bit to get a shot at Saturn
this winter. The Lumenera camera really shows some promise for
getting good shots through the TMB with it. It's got a pretty tiny
pixel micron size (4.4 microns), which should make for some good
high-resolution imaging under good sky conditions when used with the
I think the planet disk sizes are always going to run a little
smaller with my model than an SCT imager, or say, Dietmar's rig as a
comparison, due to the shorter native focal length of my tube. You
can only compensate just so far with image amplification until it
starts to break down as you know, so I'll just take what I can get
shooting at 4800mm (with the 4X) and try to maximize that the best I
can. I may try 5X at some point, but its getting pretty close to
the edge of diminishing returns at 4X with my typical seeing here.
Thanks for taking a look!
