Horsehead nubula B33 in Orion.

15 exposures 600sec. each are summed up in order to enhance the signal to noise ratio. This results in an equivalent overall exposure time of 2.5 h.
With the naked eye only the two brightest stars in the image are visible and you need at least a 10 inch telescope to get only a glimpse of the horsehead nebula.
This is not the case for photographic observation. A 3 inch Pentax 75 SDHF apochromatic refractor with a focal length of 500 mm was used to shoot this picture

Soyut fotoğraflardan sonra seyrinden zevk duyduğum fotoğraflar uzay boşluğu..

Türkiyem çok geri kalmış olmasa da çekebilsek bizde böyle şeyler..

Astronomi ve uzay bilimleri bölümlerinde bile ekipman yok. Uygulamasız eğitim...
