Tarantula in 21 Bit Dynamic range HDR in 3nm NII

[avandonk]

I dug up a full resolution image as the core of the Tarantula was saturated in the binned data.

I used HDRComposition in PI to combine the full res data and binned data into a 32 bit linear image. I then applied HDRMultiscaleTransform to a stretched 32 bit image to bring the very bright bits out so they will display at 8 bits.

This image has a dynamic range of 21 bits.

Looks amazing, will you add colour images as well?

[avandonk]

Yes I will do colour when the weather lets me Nikolas!

Intermittent clouds ruined a clear night and I only got five OIII subs.

Did a quick process anyway.
