Description

This is a collaboration with Colin Mc Gill.

He was so kind to provide me his raw frames of M51, so I tried to process the data and combine his efforts with mine.

So, this is the result.

In this image the Colin's data weight about 65%, while mine about 35%.

My data come in mainly for the core areas of the galaxies, while the background and the fainter zones are from Colin's ones.

Here are some tech data:

Colin Mc Gill:

2014/04/12

telescope: Ian King Ikaros 8" RC

camera: Atik 460EX

luminance: 43x600 sec bin 1x1

red: 22x600 sec bin 2x2

green: 27x600 sec bin 2x2

blue: 25x600 sec bin 2x2

H alpha: 19x900 sec bin 2x2

Lorenzo Siciliano:

2009/04/11 - 2009/05/12 - 2010/05/09

telescope: Celestron C11 @ 1920 mm and @ 3060 mm

camera: Sbig ST8XME

luminance: 9x1200 sec - 9x600 sec - 7x900 sec bin 1x1

red, green, blue: 5x600 sec bin 2x2

There are 13h 25min of luminance and 19h 35min of chrominance.

We hope you enjoy the result.
