             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.",
