Lunar Photometry

Posted By Joe Bergeron

Yes, it's about Roland's scopes. If anyone here is doing anything as esoteric as lunar photometry, I'd be surprised. More power to you.

I would say it's because a couple of people have some money and really want the scope. Just because the economy is bad doesn't mean everyone has gone broke.

Actually this was probably the worst GCSP for weather I've ever seen. We had only 3 really good nights, a couple marginal ones, and at least 2 total washouts. Typically we have 8 clear nights in a row, or at worst lose one or two to clouds. But I understand things back East haven't been so hot either.

It shows 93% of the resolution of the 140, and 86% of the light grasp. Compared to the older 130, the views are pretty much identical.

Of course, that's just a guess.

I was wondering why the tube and dew cap looked like simple white rectangles without shading or perspective. Then I clicked the link and realized that they actually have square cross sections. No wonder the photo looked so fake. :-)
