Starship Asterisk*

nitpicker may be on to something: long exposures, especially at high ISO can do strange things. Among other things, the camera CCD sensor chip will heat up as time goes by, for long exposures, which might shift the coloration of "strange things." Can the author fill us in on the details of...

I just downloaded the image. When I look at the EXIF data for the frame, it reports a 1 second exposure. The EXIF data shows a 59-second exposure, which is consistent with the star trails seen in the central image. I stand corrected - I used Canon's ZoomBrowser program first (which reported the 1 s...

Unequivocal: it is camera shake! I just downloaded the image. When I look at the EXIF data for the frame, it reports a 1 second exposure. Whether or not the camera was tracking, there should NOT BE ANY STAR TRAILING OR OTHER NON-LENS ARTIFACTS IN THE STAR IMAGES for such a short exposure UNLESS THE ...

I would like to know the camera+lens combination. This is clearly a fish-eye lens, and most (all?) of the scattered light around the brighter stars (which has been commented on by earlier posters) is due to lens flare. Note that as you go around the edge of the picture, the flare tends to be tangent...

Folks, Plain and simple: It’s the window glass. I hope/think the images discussed below will set to rest all the objections to this explanation. Anybody who thinks otherwise does not understand how the atmosphere works. The atmosphere is stratified horizontally, with small vertical systematic variat...
