How much does it cost to Oldham?
Oo er that's impressive. makes my attempts at taking drunken photos of the milky way on my snapper look a bit puny.

Wow wow and WOW!

Some impressive stuff there - I wonder if somehow this could be cobined with cycling.

I know, night cycling in rural areas with mounted camera's, where the cyclist has to look into the sky to take pics. That's not dangerous is it?

Is it? :whistle::biggrin:

mmm ........... they're ok. I think some HDR and Photoshop have been used on some of those pics. For the sky at night shots the ISO must have been set really high meaning a very short exposure could be used to get a very sharp image as there are no star trails which are typical of long exposures.

Don't know which you're referring to but some are on flickr - e.g. 'blazing bristlecone' winner of this category...

Canon 5D Mark II. ISO 3200. 32-second exposure. 16mm. f/3.2

Nothing wrong with high ISO on a decent dSLR, and a bit of unintentional* foreground lighting. :rolleyes:

I accidentally cast some artificial light onto the tree while setting up my dolly timelapse move.

They are great pictures, but that slideshow transition effect is terrible! It ruins the impact of the next picture in the show for the first few seconds. Considering this is all about impact and photography, that's a poor use of tech.

I agree really - 'they' move from one photo directly to a crop of the next, and then go to the whole image

Well, "you can't please everyone ... " etc. etc. etc. I find the slide show effect quite satisfying, myself. Anyway...

For the 'doubters', I can speak for those who have taken up astroimaging: processing the data from your camera to get a viewable image, is all part of the hobby. In fact many amateurs spend far more time processing than they do actually taking photos at the telescope. It's all part of the game! For instance, most of the deep sky images (those of nebulae and galaxies) in this selection, were taken using a mono CCD camera. Not something I use myself, I just use an ordinary DSLR camera (CCDs are very pricy!), but the really serious imagers go in for this ultra-sensitive medium to get the really top-notch results. Because it's a monochrome camera* you can't shoot colour directly, you have to take images through coloured filters and then 'marry' the results together in photoshop or similar, to recreate the original colours and enhance them too. Voila! The colours are strongly emphasised because the human eye, even looking through a powerful telescope, can't actually see that depth of colour: nearly everything looks sort of grey. Try it. But the colours are a great help in recognising the structure of the object in the image.

If you think that's 'cheating' - fine, I can't stop you!

*Single-shot colour CCD's do exist. Not everyone uses them.
