tested zooming

I read about this Backyard feature—using a mouse roller wheel—some where but never got 'round to trying it. I just zoomed in, while in Frame & Focus, well past 100%. It worked! In fact, I just kept going. After a time I was at over 5000%. Wow. I wondered how far one could go? That said, it felt logarithmic. After 1500%, it seemed to have little effect. I think this trick will be very useful during astrophotography.
