Near Infrared Experience

I have always found it fascinating to explore the universe at different wavelengths ever since the first digital reflexes came out. With such low quantum and low-resolution sensors, images in the hydrogen band but above all sulfur was really difficult.
With the modern monochrome ccd rooms it is much simpler. Not only that, thanks to its high sensitivity to the near infrared, it is possible to photograph in that band, to receive the light of young ones, completely wrapped in the nebula that is giving it life. In fact, around 670 nm the molecular or excited idiom becomes “Transparent” allowing us to observe what lies beyond the nebula beads.
For some time I’ve been experimenting with the unusual wavelength of 807 nm.
It’s awesome to look at the filter that allows you to receive photons from this band of electromagnetic spectrum: it looks completely black! However, in this region of the spectrum where there was only nebula, thousands of stars light up.

The first target
Investigated at these frequencies is the nebulous IC 1318 note in the heart of the swan constellation.
It is one of the regions where the presence of hydrogen clouds is more massive.
For this reason, it is one of the most spectacular objects at 807 nm (Astronomik Filter)

Another subject where great is the difference between hydrogen and near infrared is the very famous Messier 17 in  Sagittarius.
