Great picture! Congratulations, you can also distinguish the nucleus of the galaxy that "is" to be incorporated. ;-) Bravo! Of course, that a fixed / semi-fixed station helps in shooting multiple sessions :-D

Question: how come you can not see those characteristic reddish halos due to vagueness? a DSLR limit?

X Slashleo red emission nebulae are not seen because it is only one RGB recovery, it would serve to highlight a recovery in Halpha, considering that when I processed the Fits the Hubble Space Telescope (https://www.flickr.com/photos/144417955 @ N06 / 32048077610 / in / dateposted /) red nebulae not seen until I added the resumption Halpha to the red channel. Then you have to remember the limitations of an entry level SLR 4 years old :-D

Very nice new version, praise the commitment!

Too bad the flat did not work properly, you notice any speck and despite the abominable integration much noise out ... maybe you took a little too much the neck to the poor SLR ;-)

How can I eliminate those dust particles that move between shots and another, negating the correction of flat? Without using the clone stamp, otherwise I would create supernovae :-D Ps the flat box is self-built with cardboard and the bulbs of Chinese LED, total cost 2.5 euro 8-)
