Es increible como avanzo la tecnologia en camaras CCD estos ultimos años. Estas camaras estan cada vez mas accesibles al bolsillo del afisionado (si bien todabia son MUY caras) y pueden lograrse unas fotografias increibles.

Con un telescopio mediano (10”, 254mm), hoy en dia cualquier persona (con el dinero suficiente) puede sacar fotos increibles a Galaxias y Nebulosas.

Hoy en dia una buena camara con sensor CCD, esta al rededor de los 5000 u$d (una fortuna) pero hace un par de años era directamente inaccesible!

Miren algunas fotos que se pueden sacar con una camara ST-4000XCM de 4495 u$d:

NGC 4565, taken by Ed Henry with ST-2000XCM single-shot color camera through an LX200 12" SCT at f/7. 7 hours total exposure, self-guided by the ST-2000XCM, using the SBIG AO-7 Adaptive Optics accessory

Esta bien que guiar el telescopio automaticamente durante 7horas no es facil, pero con buenos equipos, se puede. Hay modelos con doble chip, que usan uno de los chips para sacar la foto y el otro para guiar la montura robotizada del telescopio.

M42, Orion Nebula, taken by Ed Henry with ST-2000XCM single-shot color camera through a 100mm TMB refractor at f/8.  3 hour exposure, self-guided by the ST-2000XCM.

Nada que envidiarle al Hubble! hay fotos sacadas por afisionados que son realmente increibles, que hubiera dicho Galileo si le mostramos una de estas?!

Tendre que ahorrar y ver si el año que viene estan mas baratos :S
