M51 desde Hontanar

[akeru]

Os dejo la M51 que saqué desde Hontanar, a pocos kilómetros de Navas. Está hecha con el 150/750 y Canon EOS1000D a iso800 (12x60"+53x300"+26x600") apilado y registrado con DSS (median), procesado con Startools, Fitswork para deconvolución (ya que el seeing era muy malo y quise sacar algo más de detalle a los brazos de la galaxia), photoshop (mínimos retoques de histograma, curvas y color).

El guiado fue muy bueno durante las dos noches, a pesar de que el seeing fue muy malo (IV), la segunda noche sobre todo resultaba especialmente dificil enfocar.
Las estrellas han aparecido gordotas y la galaxia con poco detalle, el procesado ha sido complejo.

Podéis verla a mejor resolución en Astrobin http://www.astrobin.com/181912/

A pesar de las dificultades (mal seeing y muchísimo ruido de la 1000D estoy muy contento con el resultado, hace 5 años M51 fue mi primera fotografía que hice con este mismo equipo:

Te ha quedado de lujo.

Un saludo

Estupenda.

Muchas gracias por vuestros comentarios. He aplicado un drizzlex3 para intentar sacar más detalle de la galaxia. Aquí el recorte:

Akeru me gusta mas esta recortada, la veo mas natural. Es una lastima cuando te dispones a tirar y estas dos noches y ves que los resultados no son de tu gusto. Te da una RABIAAAAAAA

A mi también me gusta mas esta segunda. Me parece muy buena
