Analog cameras require a "frame grabber", which is a piece of hardware, to interact with a computer (USB instrument.) The original Astrolive was made to work with analog devices. The new Astrolive will is targeted at USB devices.
The analog cameras (older Mallincams) will work with a simple TV, no computer required, & as I understand, produce fantastic results. You get a nice full TV screen of gorgeous pictures unpolluted by histograms & other such things.
Mallincam has developed the Sky Raider series which are USB (usb = digital, analog = analog). USB devices produce files that are easy to save & to process with things like Photoshop. The framegrabber does convert the analog output to digital so in can be viewed & saved on computers. The down side to all of the USB devices & their programs is a computer screen full of distracting "boxes."
Now I am a newbie & that is my take.
