PPT-Collimation and Star Testing

An RVAS Meeting Program By Frank Baratta March 20 2017 Horsehead Nebula Public domain image at PixaBaycom F Baratta 2017 Graphics and images F Baratta 2017 except as noted bad collimation is the number one killer of telescopes world wide . By observing outoffocus star images you can test whether your telescopes optics are aligned Place a star in the centre of the field of view and move the focuser so that the image is slightly out of focus If the seeing conditions are good you will se Alessandro . variola. , . lal. - in2p3 – . cnrs.

The aim of this experiment is to demonstrate that bent crystals can work as a “smart deflector” on primary halo particles. Bruce C. Brown. Main Injector Department. 29 July 2015. Meeting Outline.

Par le petit trou de l’oculaire de collimation vous devriez voir le miroir secondaire avec le miroir primaire qui s'y réfléchit. Le miroir secondaire devrait paraître centré et bien rond. . reach.
