It's been some time since the Satellite Toolkit was released as freeware to the public (the add-ons are where the money is to be made, I suppose). I finally got around to having the free CD ROM mailed to me (see http://www.stk.com for more info), and was absolutely aghast to read the install requirement for the Windows version was 220 megabytes! That's not a misprint. Two-Two-Zero! Egad! I don't even have that much free on my 2 GB harddisk. Before I commit space to this product, is there *ANYONE* among the visual observer community who has found it worthwhile? I recall only a scant handful of posts ever mentioning the program, and at the time I don't think any SeeSat'ers said they were actually using it. Is that still the case?
