[quote:UP 596140:MV83MDAwMzhfMTExMjk3OTFfMTk4NjY1NTA=] [quote:Anonymous Coward 612501] .... PLEASE, folks - You *can't* expect consumer cameras to autofocus on distant objects in the sky. They are not designed for this sort of use. Zooming right in on an object that is out of focus, just shows lens bokeh and the shape of the lens aperture. Dunno about anyone else, but I'd actually like to see the OBJECT!! ======== If it is venus? Here you can view venus rising taken by same cam as above,you can see the movement of venus ?,as it moves to its highest point.manual focus being used, it is not out focus it is the movement of venus filmed in high shutter speed and turning as she is rising, that makes you think it is out of focus she is moving veryfast and sun on her backside is that gas at 11oclock. http://www.youtube.com/watch?v=D5WU261lFKA [/quote] Thanks, Skywatcher! The good bits - good tripod work, and you have included the background zoomed out so we can pretty much eliminate movement (other than that lovely smooth, slow progress of the planet as the earth rotates...) - manual focus!! Yay, it doesn't keep racking back and forth! But (yeah there's always a but..) - it would be even better to *show* what happens as you change focus during thew shot. In every case, your video *jumps* to different focus effects,a nd we can't see what is ahppening while you focus. Yes, the image will wobble around a bit, but it makes it much easier to see when the objects is truly smallest, and how the bokeh becomes visible as it goes further and further out of focus. A couple of additional points: At that exposure level, Venus is overexposing. The camera will expose for the vast expanse of sky, but Venus is MUCH brighter. So the final resulting image is 'bloomed out'. When that happens, the recorded image is much larger than the object, you lose the objects original shape, and on many sensors you also get those telltale black edges around the edge of the object. Again, it is sensor detail, not object detail. Can you adjust the exposure and dial it down? The first bit uses digital zoom, yes? Problem with digital zoom is that it has to 'guess' the extra image information to add, and if the object is overexposed and bloomed as above, it will trip over those edges and give you funny shapes. And if the object is even the tiniest bit out of foucs, then it will add to the problems. I don't recommend digital zoom for getting the most accurate detail, and it would be worthwhile if you read your manual and the warnings they (usually) give about it. But thanks for that one. Keep it up! [/quote]
Original Message
Have always loved the stars and staring up at the night sky, recently spotted a much brighter object than i've ever noticed before. I am aware of the presence of Jupiter and Venus, this new object seems markedly brighter than anything i've observed before, its seems to glare and undulate. Friends who i've observed it with also seem struck by its vividness. After recently reading about the brown dwarf 'Nubira' and its eliptical orbit, was wondering if this could be the giant on its return. If its not, what is it please???
