Astrophotography

     
   

A rare, urban view of planet Mercury

 

I have never seen Mercury before - hardly thought I ever would. But on the evening of 21 April 2009 at ESDT 21:56 (UT 19:56) it suddenly was there, visible to the naked eye in spite of air pollution and all.

Thanks to my trusty "old" (2005-release) digital SLR, Pentax *ist DL and my even older (1981) Pentax SMC K-lens at 50mm f/2.8 this precious moment was also recorded !

Origninal raw (pef) file converted to 8-bit jpg. First image otherwise unprocessed 8 sec exposure at ISO 200 with Pentax *ist DL digital SLR and Pentax SMC K-lens, 50 mm focal length at f/2.8. Note on EXIF data: Camera clock is set to EST (not ESDT).

On 24 April, sky conditions had improved and Mercury was easily visible to the naked eye. It even recorded well with my small Olympus C50 Zoom compact camera (although with some focusing flaws).

There is a moon for every camera and every lens - and for your digital imaging software too.

 

Landscape Photography? Astrophotography? Or both?

     
    A taste of Deep-sky
Living in the midst of a city makes many things easy - but not deep-sky astrophotography. Haze, dust/smog and in particular ligt pollution - the gastly mixture of spectral lines from street lights, shop windows, vehicles, spots and posters block out all but the brightest stars to the naked eye and provide a nasty, brigt and pinkish-reddish tint to one's astro images.

However, the advent of digital cameras and digital imaging processing makes possible to suppress a surprisingly large part of the effect of light pollution on city-astrophotography - if not for scientific purposes then at least for aesthetic ones.

There is no substitute for a truly dark night sky, but fairly simple digital image processing techniques may provide a bit of a taste of the deep-sky wonders waiting out there.
