Big Bertha 2.0: Yes, It Works
A few tweaks required:
1. I couldn't buy any blackout cloth at the Joann Fabrics on Fairview last night--they were all out. And in the early evening, there was still enough ambient lighting that it was a problem. As darkness fell, the image quality improved quite a bit.
2. Because the mirror is better supported, it does seem that Big Bertha 2.0 does have a somewhat better image than before.
3. There is still a turned edge on the main mirror--but it is much easier to get in and add a mask to cover that over now.
4. I probably need to slot the holes where the upper cage is held to the rails, so that I can turn the focuser--otherwise you get some rather awkward positions.
5. I still need to attach the finder--there's little hope of finding anything except the Moon otherwise.
6. It is still a little creaky--lots of discomforting noises as I move it around, but it seems pretty stiff.
