Well the detail is magnificently sharp, but too much blue for my liking.

There's a lot of good data there.

You've succeeded in bringing out faint material without burning out the tarantula. And you've handled the darker areas very well, with nice contrast.

So far, so excellent, but the highlights look very muted, as if you've held back the Tarantula so it doesn't burn out. Perhaps you've held it back too much.

Geoff, anything I can say in reply you already know ... the mere fact that we can see the Tarantula with the naked eye means that it is very bright at green and blue wavelengths. I often lament that our sensitivity to deep red light shuts down at night. Imagine if we could see all of the H alpha emission nebulae sprawling across the night sky? Now that would be awesome.

Fair comment. Perhaps I have flattened the core to excess. It is always difficult finding a good balance between revealing all of the detail and showing the full range of brightness levels.

A unique look at the Tarantula and surrounding nebula. You have certainly shown the detail there.

The dynamic range of the scene though has been artificially reduced as we all know those inner stars of the Tarantula are massive and bright.

Perhaps bring that up a bit more and it would be more appealing.

Greg.
