This is not easily done, but it much more easily done with the Nikons than with other cameras.
The results can be stunning.
If you really want to get into a discussion about all this, log onto the UseNet group: rec.photo.digital
The people there are *very* knowledgeable and very helpful.
But the outcome will be the same: Nikon Coolpix. The most expensive one you can afford.
The problem is that that the scope will cost you close to $1000, if not more. Add another $300 for the tripod (think Gitzo), and a couple hundred more for the stuff that all makes everything work together.
Then we have the computer, which will not be good enough.
If you get into digital photography, you need to be careful. It is probably best to go either very small or to be prepared to get in fairly deep. A budget of $10,000 or more is not unreasonable if you want to get into the deep end.
The shallow end is not bad. There is a lot you can do there. I'm not sure which cameras are considered to be best there these days, but I know the Konicas used to have have a good reputation. I'd stay away from the Sonys.
You really need to talk to the people on rec.photo.digital
But, again, you originally asked which which camera is best. The answer to the question is Nikon.
Fwiw, this comes from someone who is a longtime fan of Canons.
I'm about to give you some good advice. Listen closely.
Think about what it is you want to do, and then call the people at Eagle Optics.
It was around $400 so it isn't an expensive camera, and obviously not professional quality - but we take some pretty nice shots with it............
For a family camera, I would recommend the Olympus with the 10 to 1 zoom. My brother has it, and love's it. Then get a memory card reader to attach to your computer.
