Hi Philippe,

The depth, tonal range and resolution of this image are remarkable. However, I'd go one step back stretching it to prevent clipped pixels and excessively darkened areas.

Hi Juan
Thank you very much, yes, I think the dark is too dark  8)
I will process a new version.
Also, the HaRGB will be added.

It is one of my 1rst images with this new setup. Not easy !

Best,

that is a really nice image - i really want one of those OTAs but my understanding is that since it's so fast it is hard to get the sensor perfectly orthogonal to the optical axis.

then again my 200mm f/2.8 lens is pretty fast and even though there's a bit of tilt, it's not too bad. plus i am using an 8300 - it must be a lot harder to align with that big sensor you are using.

Wow, that's a dramatic image, very compelling! It feels as if one could dive into it.

cheers
