Description

I had to post it on a low resolution beacuse of my free plan here on AstroBin and also because the original TIFF file was 1,84GB :(

My goals with this image was reveal some of the H-alpha nebulosity that surrounds the Eta Carinae Nebula region. This picture is also the first light with my Nikon D5300 since it has been modded and the first time I used a H-alpha filter with it. I still have a lot to learn either in image acquisition and in processing stage, but I tried PixInsight for the first time in this image and I think the image came out to really exceed my expectations. I also have to mention my friend Mauricio Christiano de Souza, who helped me a lot with PixInsight.
