Details:
Summer time leads the spectacle of the 3 conspicuous stars (Deneb, Vega & Altair), the Summer Triangle asterism, high in the sky (for mid-northern observers). Here, a spinning wind turbine seems to stir the dark and pink nebulae complex within the triangle. In the close up view, some satellites passed during the exposure, one showing a 'splitted' track due to the turbine blades. Single & uncropped shots Nikon D600 full spectrum & Nikkor AI 28mm @f/4 30s ISO 5000 (portrait); Nikkor AI 50mm @f/2,8 30s ISO 3200, both guided. More at flickr.com/eirexas

Thanks for your comment. This ía a specially modified camera in order to increse wavelength sensitivity of the chip. Low pass IR-cut filter was removed and replaced for a IR-UV transmitíng surface. So, the chip extends its sensitivity from near IR to UV, permitting to register H-alpha radiation from emission nebulae.

I meant this is, increase, and transmitting.
