Default Today's humble offerings, from Herschel to Sol

Well, here's an assortment from Sunday morning and afternoon.

It seems like the seeing has been pathetic here . . . . forever. Perhaps, as suggested by Diets' comment "it`s fasciniating how well the human eye can cope with bad seeing.
the camera doesn`t..."
, I've just never appreciated how poor the seeing could be and yet I enjoyed the view.

Anyway, for the image I've named Herschel, I took lots of big jpegs in succession, but they were so different from one another due to the poor seeing that Registax often lost track of the points I'd selected. To eliminate this problem, I took a 768x1024 crop out of each of the originals. The crop was centred on that peak on the edge of Herschel. Then I stacked the 88 cropped images (but I forget the proportion that was used in the stack). Tedious for sure, but it worked.

Then, after giving up on the AVI of crater Schiller, I was inspired by triclon's solar image with the sunspot. The attached image is the best of about thirty that I did. I found it very hard to achieve focus, and I think that's just typical of trying to get pictures of the sun in the afternoon. The air is too turbulent. (That image was done at 1/1250 second, with a Thousand Oaks 2+ filter).

Finally, the clouds obscured the view, and I got the last one as they moved in.

Torsten,

Nice images. I like the color in the solar shots. Keep on experimenting, that's how we get better.

Clear skies,

--Andy
