"Live" is all relative...Most would consider "Live" video to be 15 frames/sec. Even if the DSI could do that, you wouldn't see much of anything. If you did 1 frame every 5 sec, you may see a noisy fuzz blob, possibly with a hint of structure depending on your f/ratio. 30 seconds to a minute, you'll get some color and structure. 1-2 minutes, you're looking pretty good.
Is 1 frame every 30 seconds "Live"? Well, it's better than film for sure. It's all a matter of semantics, I guess.
Looks like you've captured some great data there. I feel for you on the filters for the Pro...They just aren't right. May want to call Meade about them and see if they can't provide a new set or something...let me know if you need some backup.
The detail you were able to get is great! Good work!
