abstract = "Airglow observations in the Southern Brazil have been carried out
at the Southern Space Observatory (SSO/CRS-INPE), in a continuous
mode, by an automated airglow imager since April 2017 with the aim
of study the dynamics associated to gravity waves in the upper
Mesosphere region (around 90 km height). However, the first
attempt to install and operate an adapted airglow imager started
in January 2017. This new system was adapted from the former
airglow imager operated at Ferraz Antarctic Station in 2007, 2010
and 2011. The system re-assembled in the beginning of 2017 had a
very short optical system and it was not possible to obtain the
correct focus in the imagens. Then, new different telecentric
systems were tested in order to find the correct focal distance,
and also an optimum new optical system that should give an
amplified image with a best spatial resolution (a larger number of
pixels in the CCD should be used) as compared to the images
obtained with the first configuration of this system in 2007.
After several tests with distinct telecentric sizes and relative
distances between lens/filter and between the end of the
telecentric and the CCD, an ideal configuration was found. This
new configuration generates images approximately in the half part
the full CCD size (1024 X 1024 pixels), with possibility of
finding a correct focus at the stars. After cropping the original
image, it was possible the maximize the proper view of the images
in an area of 512 X 512 pixels. In this work we will present this
new camera assembling and the first results on gravity waves
observation and characterization in the upper Mesosphere over the
Southern Brazil.",
