Here is another picture of my favorite Veil nebula. The first attempt here with a long focal length (1000 mm), the second attempt here with a shorter focal length (730 mm), and finally third here with the shortest focal length I have (430 mm). Still, I haven’t captured everything of the nebula last year and this year I focused my smallest telescope on the western part of the Veil nebula and created a mosaic.
The picture, as well as the previous ones, are bi-color images. I captured hydrogen alpha (Ha) and oxygen III (OIII) narrow band images and inserted the Ha image into the red channel and OIII into the green and blue channels.

[…] deep-space object by me is the Veil nebula. I simply love this supernova remnant. The previous mosaic picture revealed that the eastern part is slightly brighter, therefore I pointed my telescope with a longer […]
