Spaceshuttle and ISS in one frame...

During a astrophotography session I recently got both Spaceshuttle and ISS on one frame, or to be more precise on several frames.

The first object with some "haze" around it is the Discovery dumping excess water (weight) before returning to Earth. Discovery is "followed" by the ISS.

Further examples of this event can be seen here:

Doing the Time Lapse!

Howdy,

together with Vinc over at
One-Eye-Vision I have stepped into the interesting field of Astronomic-TimeLapse photography, which is a beautiful science on itself. "TimeLapse" means that still images made using a intervalometer with a Digital SLR, get combined into a movie using Adobe Premiere, AfterEffects, FCP or the like... Here photography merges with videography, and still images get moving.

You may ask why one doesn't use a Videocamera or the Movie function of a DSLR for that purpose? The reason is the lack of sensitivity of current Video Camera designs for Astronomic nightshots, that require a exposure time of 4-30 seconds (or more) due to the low light scene.

Well, you can find me a lot at
TimeScapes.org and OpenMoco.org these days reading tons of tutorials and how-tows... Awesome community there!

With Timelapse I am deeply impressed with the works of
Tom Lowe and German Master Bernd Proeschold... For a really cool feature about Bernd on German WDR TV, here we go... This is how a TL is done on a very clean base - the results are awesome...

Happy timelapsing!

Adventures in Deep Sky Astrophotography

I've been quite busy last months with a lot of projects and of course our little daughter Elena :), so it was relatively silent here... But if you know me that doesn't mean that nothing's happening - the opposite is the case!

For example one of the assignments (for a well known German Nature Magazine) requires me doing astrophotographic images - I dubbed it "CSI Orion".

So I took a deep dive into this special kind of photography (a exciting new challenge anyway). And I have to say that Astrophotography totally rocks! It inherits both a STEEP learning curve and requires all my photographic and post processing skills.

The equipment used for Astro-images is also a new experience: I am using
AstroTrac's TT320X-AG and a special modded astronomic Merlin controller head (which is also capable of GigaPixel Photography as a nice side effect due to the tweaks by the frenchies at Kolor). The Merlin Controller is completed by OpenMoco.org's legendary Stage Zero Dolly (another story) for a full programmable 4-Axis Camera rig. Amazing. Lot's of testing, testing, testing setups etc.

Furthermore the outdoor side of the project appeals to the adventurer in me: cold feet, drinking tons of hot tea from thermo bottles (if I do not forget them home), hanging out in dark remote mountain areas for the best possible clear and dark skies, long nights alone - which is very demanding. but one is busy: navigating the sky for galaxies and nebulae staying awake triggering camera shutters, changing batteries, programming intervalometers, managing external power supplies, controlling astrophotographic gear. Like back in the days...

I can only say: The first moment I saw the M108 spiral Galaxy appearing on the Monitor of my D700 was truly magic. But also hard work with hours of searching and adjusting the extremely narrow view of field one gets at 1500 mm lens, and tuning in exposure and ISO.
