En 2014
acabé un mosaico de una zona espectacular en Auriga, llena de cúmulos
estelares, nebulosas de hidrógeno más o menos compactas y objetos curiosos como
los &quot;renacuajos&quot;. Ese mosaico me llevó montones de horas y es todavía
una de las fotos de las que me siento más contento.

Esta
foto me ha llevado muchas noches de intentos y sesiones más o menos
productivas, debido sobre todo al (mal) tiempo. Empecé en Septiembre, y a
finales de Noviembre todavía me quedaba alguna hora por acumular, y el Cisne ya
estaba volando hacia el Oeste, más pronto cada noche… Hasta que el 2 de
Diciembre lo pude dar por terminado, justo a tiempo.

started this photo one year ago, with the H-alpha frames, and I have just
finished it now in January. It has taken a lot of effort for many reasons: of
course the bad weather, or not so bad weather but poor seeing, sometimes
collecting only two or three frames per night, and therefore having to use many

astrophotography made using narrow band filters, i.e. those filters that
only let pass light of a very well determined color. The purity of the color is
given by how narrow is the slice of the light spectrum (the rainbow, so to say)
that the filters allows to pass. I use filters with 5 nanometers band width,
that is very narrow.
