Very, very interesting picture of something. The whole series looks great.
Could you give us more detail of where and, if possible, what settings ?

I am assuming these are all in the USA.

All the photos were taken from my backyard in California. I used a Canon
XTi SLR Digital Camera with Celestron 8 telescope using a t-ring and
t-adapter. All of the pics were taken at the maximum picture size and
detail (10 mp) but were reduced to 860x480 for posting on the newsgroup.
The scope is a set F-10. You generally have to use aperature preferred
which then adusts to the correct shutter speed. You can contorol things
more by playing with the exposure using ASA settings. On a bright day you
can use 100 with no problem. If the light is low you need to go up to 400
but no higher. Shooting the planes requires at least 1/600th shutter speed
and if they are close about 1/1500. I usually use auto white balance (that
seems to do it) and set the detail on around 3/4 sharp and keep everything
else neutral. All focusing is manual and mirror lockup will not work
because you need to follow the target. However, mirror lockup only comes
into play using slow shutter speeds. You can override the shutter speed on
aperature preferred by going to shutter speed preferred. You can increase
shutter speed considerably without the picture going dark on you. Even if
it does you can save it using picture software. I use Adobe Elements 5.0
and you can do almost unlimited procedures to bring out the picture. Some
of these include brightness, contrast, midtones, (multiple controls) plus
sharpening, noise removal, cropping and resizing, auotmated color
correction -- the list goes on an on. Hope this helps.

Fantastic Rex. Really interesting,
