I sit in my little warm hutch (or car, maybe) on a cold March night
atop a mountain anticipating a laptop full of great images. I have
a remote control for the telescope and astronomy software connected
between my laptop and telescope for selecting interesting objects.
My Maxxum 7D is mounted on the scope for tracking, and I have a
nice lens on the camera pre-focused for the stars. I'm using my
USB connection and DiMAGE transfer to pull the image and view it
near-real time on my 15" laptop LCD instead of the 2 1/2" camera
LCD.
Now, while sitting in my warm hutch, I decide to take a photo of
the Oriion nebula. I slew the telescope into position, bring up
Dimage Transfer, tell my camera to remotely store images and have
my RC-1000L remote cord in my lap. I set my exposure to ... oh
wait, I get out of the hutch, set my exposure to 15 seconds and
F/22. I get back in the hutch, get settled, and trigger the camera
with my remote cord. Wow, what a ... darn, ISO set at 200, need to
set it to 800 and try again. I get out of the hutch, set my ISO, I
get back in the hutch, get settled, and trigger the camera with my
remote cord. Wow, what a ... hmm, too dark, gotta set the exposure
to, well, 30 seconds. Better set it to full manual now, instead of
Ps mode. OK, looking good, but still underexposed. Maybe ISO
1600. I get out of the hutch, set my ISO, I get back in the
hutch, get settled, and trigger the camera with my remote cord.
Wow, what a ...
You get my point. There's far more to remotely controlling the
camera than being able to see the image live. Add some basic
scripting capabilities, and you can perform multi-step image
processing that's tough to do on-camera.
I'm admittedly a gadget freak, but I think there are legitimate
uses for this software on the 7D. I also believe those legitimate
uses are hardly diminished in value just because you don't get a
live image.
