Here are some of my constraints:
I have an equatorial tracking mount for the 4" refractor I'll be
using. I am anticipating a trip to Phoenix over x-mas so my travel
setup will be limited to an alt-az mount (no tracking). It would be
nice if I could collect several images of Mars before it drifts out of
my field of view while using the alt-az mount on this trip.
This is a deal killer, IMO. You will be at high power and using a small
sensor. Tracking is mandatory. Bear in mind it doesn't have to be very
good tracking- a cheap equatorial mount with a single axis,
non-computerized drive is more than adequate. But without tracking, you
will be spending all your time trying to get the image on the chip, and
then you'll just get a few frames, not enough to use effectively. Figure
out a way to take a tracking mount.
It helps a lot that you'll be in a part of the country that often has
good seeing, but for the best results with video planetary imaging you
want hundreds of frames, if not thousands.
I have a laptop.
Right off I am not interested in buying a digital SLR....although
perhaps the cost of a system may approach the cost of a digital SLR
which may make it the best option.
That's good, because a DSLR is completely the wrong camera for planetary
imaging. You want an inexpensive webcam- I've had good luck with the
Celestron NexImage. Many Philips and Logitech webcams are also quite
good.
I was looking at Meade's DSI pro cameras. Would they work for me?
For planetary imaging, you would be better off with a simple webcam
(which will be a lot cheaper, too).
