If it's got a good frame rate you can easily increase resolution beyond the CCD resolution. Simple explanation is:
1. Take a bunch of images which are all slightly misaligned
2. Upscale by a factor of 2 or 3 or whatever
3. Align all the images (as in, if there's a star in the image, align all the stars, not align the pixel grids)
4. Merge them
You need to have a bit of motion in the images so that the light sources aren't all perfectly aligned with the pixels but it's not difficult.

That might work for a large target like the moon but not for a smaller one like a nebula. I'll check that out but I think the depth of field is fixed so you can't zoom in to targets and do as you suggest.

On a side note, it's not good for planetary observation, tho' there may be a software update to improve that shortly. It's great that you can use it for solar observation as well, it's a pretty versatile tool!

but that's how most of the pictures are made, you take thousands of images with a tracking telescope and then stack them and do loads of post processing.
