hi Diego

If you're seeing a difference between Photoshop version and JPG it may be your colour settings and profiles. e.g. if the file is in Adobe RGB it may look great in Photoshop (colour managed application) but not elsewhere.

Are you viewing the JPG in Photoshop or only in another application?

Send me a download link for the Photoshop file and I'll have a look.

Very nice overall. The brownish hue to the nebula though as you say could have more red in it. Is that what you were referring to?
