My thanks to C. Jacques, M. Moura, J. R. Barros and E. Pimentel from SONEAR Observatory, Brazil.

Thanks for watching!

Cheers,
Luiz Duczmal

PS: I have revised the original image and corrected the background.

Thanks Marc for the kind comment, very much appreciated.
I have just uploaded a revised version of the image, hope that you like it.

Lovely image.
Great job, well done.:thumbsup:

Hi Luiz,
Nice picture - top data.
I think the latest version is a bit too dark which
has caused the nice faint yellow/brown area at the bottom left corner
of the Tarantula to be lost although you've fixed what looked like a gradient.

cheers

Thanks for the input Allan, I think you are right. I must work now with the Dynamic Background Extractor, instead of the Automatic.
Best,
Luiz

Thanks Ingrid for the kind comments.

Hi Luiz,
It's all subjective really but -
the free program called Fitswork4 would fix it up in 1 minute.

Go to:
processing
background flatten
background gradient removal manual


cheers

Hi Allan,

I have uploaded a new revision, with an improved background correction and a less aggressive contrast. Now I think the red clouds are better displayed. Thank you VERY MUCH for your observations!

Cheers,

That's better - have you tried Fitswork4?

I use it all the time & it's great.

Only Tarantula ?!?!

There, you can see NGC 2074, an unidentified group, NGC 2077, NGC 2086, NGC 2083.

Very good field. :thumbsup:

Hi Allan,

Thanks for the info. I took a look at it, and it seems a nice free program with many useful features.
I opted to use PixInsight Dynamic Background Extractor, however, due to the complicated geometry required for the background correction in my case (I don't know how to process complex background with FitsWork4).

Thanks again for the tip.

Thanks Jsmoraes, a name as "Tarantula Nebula Field" should be more appropriate. I took a look at your LMC objects, a nice collection.
