How to Make Bahtinov Mask, PDF Templates - DeepSky Watch. Introduction Focusing mask which was invented by Pavel Bahtinov is considered to be the easiest, the fastest and an accurate tool for manual focusing.
During the focusing procedure the mask is placed in front of telescope's aperture and then the telescope should be pointed to a bright star. Bahtinov mask produces 3 diffraction spikes: Two of them form an "X" shape, and another spike crosses it, forming a "Ж" shape. The central spike moves left or right (relative to the diagonal "X" spikes) according to focus position. MFN rule for exposure time. J’ai développé en 2010 une règle qui permet de calculer (assez) facilement le temps de pose maximal pour prendre un ciel étoilé en photo sans que les étoiles ne filent trop.
Cette règle se substitue à l’antique « règle des 500 » qui donne des résultats trop incertains. La règle NPF est un peu plus complexe que la règle des 500. Mais elle a le mérite de donner immédiatement et à coup sûr le temps de pose idéal pour avoir des étoiles bien ponctuelles quand on prend des photos sans suivi. La règle NPF est implémentée dans diverses applications, par exemple PhotoPills, PlanIt! Amazon. Photons to Photos. Imaging - Tips, Tricks and Techniques.
