Visuallty, I could really see a big difference with the DS in place--much more surface detail was visible, but prominences seemed a little fainter and not as detailed. I took the following images for comparison. I cropped then to about 25% of size, and oversharpened them to exaggerate differences. Here is the DS image:
And here is the standard image:
The DS image had more features and a more balanced look. The standard seems better focused, which highlights one of the issues I'm having when imaging. The DS is very hard to focus optimally. Unstacked, you have a real sense of "snap: as the scope reaches focus. I don't get that with the DS and I seem to be hunting for he least hazy image position on focus. I should point out that this is only an issue when imaging. Visually, focus using the DS is sharp and clear.
