Hello Guys, We had another one, so here is a link to see an image I took during totality: http://www.claysturner.com/eclipse/lunareclipse.jpg feedback welcome. We can even pull this on topic by discussing drizzle techniques for image processing. Clay

I missed that eclipse, as it occured at 4AM local time. There was one lunar eclipse in 2000 or 2001 which happened around 10PM local time. The weather was clear, so everybody saw everything. It was very interesting to see how the lights went off in one house after the other, as people turned off the indoor lights in order to see better.> We can even pull this on topic by discussing drizzle > techniques for image processing.Why? ;) If you really want to go that way: I just got a copy of the 2008 edition of Gonzales & Woods' classic text on image processing. Compared to the 1987 and 1992 editions, this new one is far more focused on practical techniques as opposed to concepts. It still requires a bit of work to decode the useful techniques from the text, but not nearly as much as with the previous editions. Rune

Wasn't it something like Gonzales and Wintz??It was originally, according to the preface of this new book. Apparently Gonzales and Wintz wrote the first couple of editions, and then it became Gonzales and Woods. The full story is outlined in the 2008 book. Rune

Since I've always done RF and telco apps, I never messed with processing poor images alot. Now that I'm getting into astrophotography I'm doing quite a bit I'm looking at their tried and true methods. Thanks for the pointer on the book. I have been playing quite a bit with stacking images and it works quite well. Clay

One thing I remember about it was that we had a single "lab copy" that was jealously guarded because it was so eye-wateringly expensive. Is that still the case? Cheers mark-r --

Is that still the case?I picked up my copy in the bookstore for the equivalent of USD 100 or so. It is used in a class at the university, so there may be some volume discounts factored in, but by and large it is more or less standard price for textbooks. Rune
