		Researchers and students of the Andean Geological Studies Group (UNS-CONICET) hiking over Early Cretaceous sedimentary rocks of the Neuquén basin, Argentina, among native Patagonian flora. Uplift of these strata took place as they got folded and faulted due to compressive tectonics, inviting weathering and erosion to the craft of modern landscape.. Valentalf

The photograph was taken during a research stay in Belem de Para (Brazil) aimed at studying the places in which the relationships between human beings and the environment takes place in Amazonia. Jäkel.Andrés		A male Green Kingfisher (Chloroceryle americana) perched on a branch, seen from the front, observed at the Iberá Provincial Park in Corrientes, Argentina. Ezequiel Ignacio Vera		Close-up dorsal view of a specimen of Tenebrio molitor, also known as the mealworm, viewed through a magnifying glass. The insect exhibits clear signs of infection by the entomopathogenic fungus Beauveria bassiana. The surface of the insect's exoskeleton reveals the presence of characteristic structures of the hyaline fungus, such as spores and mycelium. The infective cycle of Beauveria bassiana begins with the adherence of conidia to the insect's cuticle, leading to entry, colonization, and the eventual death of T. molitor. Subsequently, the fungus emerges on the insect's surface and horizontally spreads to other insects, initiating new infective cycles. This image is valuable for illustrating the biology and pathology of the host-fungus relationship and may be of interest in the context of entomology and biological pest control.

Astronomy images from Argentina
		National winner
		The emission nebula NGC 3324, known as the Gabriela Mistral Nebula, is located about 7,600 light years away, in the southern constellation of Carina. The image was acquired with a Newtonian telescope, dedicated cooled mono astronomical camera, using narrow band filters (Sii, Ha, Oiii), all mounted on a motorized equatorial mount. Multiple hours of information were acquired for each filter in individual 3-min shots, and 3 mono master stacks were obtained which, when mixed, obtained the color image. This image is the result of selectively filtering the entire visible spectrum of light except the spectral lines of the most abundant elements in emission nebulae, such as doubly ionized Sulfur (Sii), alpha Hydrogen (Ha) and triply ionized oxygen (Oiii). This allows these images to be taken from cities with as much light pollution as Córdoba. The Hubble palette is known as SHO due to the mapping of the Sii signal as red (R), Ha as green (G), and Oiii as blue (B). Date and place of acquisition: April 2020, Córdoba Capital, Córdoba, Argentina. Main equipment: camera: ZWO ASI 1600 mm-pro, telescope: SW Explorer 200pds+SW Coma corrector, equatorial mount: SW EQ6-R-Pro, electronic focuser: ZWO EAF, filter wheel: ZWO 7x2" EFW, Optolong Narrowband Filters. Guiding equipment: guidescope: starguider 60/240 mm, guide camera: ZWO ASI 120mm mini. Total Integration Time: 16.5 h: 160x180” lights Ha, 85x180” lights Oiii, 85x180” lights Sii. Calibration images: 100 darks, 100 dark-flats, 100 flats per filter. Softwares used: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 and Photoshop.

The emission nebula NGC 6188, which resembles two dragons, is located about 4,000 light years away, in the constellation Ara, only visible from the Southern Hemisphere. The image was acquired with a Newtonian telescope, dedicated cooled mono astronomical camera, using narrow band filters (Sii, Ha, Oiii), all mounted on a motorized equatorial mount. 3.5 h of information were acquired for each filter in 3-min shots, and 3 mono master stacks were obtained, which when mixed yielded the color image. This image is the result of selectively filtering the entire visible spectrum of light except the spectral lines of the most abundant elements in emission nebulae, such as doubly ionized Sulfur (Sii), alpha Hydrogen (Ha) and triply ionized oxygen (Oiii). This allows these images to be taken from cities with as much light pollution as Córdoba. The Hubble palette is known as SHO due to the mapping of the Sii signal as red (R), Ha as green (G), and Oiii as blue (B).

Cappellettiariel		With the camera lens facing east, the panoramic view of this light pollution-free sky reveals an almost perfect firmament between the Pleiades to Canopus, Orion rising in the middle and Sirius looming behind the southernmost mountain. It is the crown of the small point of light that comes from a small town called Ampimpa, where one of the first astronomical observatories in the region was established. The photo is taken 11km from the place, on the outskirts of a city in Tucumán Province called Amaicha del Valle. Valemops		In this wide-field 1x2 mosaic we can see NGC 3576 (Statue of Liberty Nebula) in the lower left margin, the star cluster NGC 3532 (Whishing Well) in the upper left margin, and the Great Carina Nebula (NGC 3372) in the center, in the upper right margin the Gabriela Mistral Nebula (NGC 3324) and the Gem star cluster (NGC 3293).

The name "Trifid", was coined by astronomer John Herschel, and means "divided into three lobes", it is a nebula of both emission (reddish part) and reflection (blue part), and absorption (dark nebula) at the same time. time. It is approximately 5,500 light years away, located in the constellation of Sagittarius. The image was acquired with a Newtonian telescope, dedicated cooled mono astronomical camera, using color and luminance (LRGB) filters, all mounted on a motorized equatorial mount. Multiple hours of information were acquired for each filter in individual 2-min shots, and 4 mono master stacks were obtained, which when mixed yielded the color image. For this image, in addition to the LRGB filters, an anti-light pollution filter was used that selectively filters the wavelengths of the main light sources of a city. This, together with the great brightness of the M20 nebula, allows these images to be taken from cities with as much light pollution as Córdoba. Date and place of acquisition: November 2020, Córdoba Capital, Córdoba, Argentina. Main equipment: camera: ZWO ASI 1600 mm-pro, telescope: SW Explorer 250pds+SW Coma corrector, equatorial mount: SW EQ6-R-Pro, electronic focuser: ZWO EAF, filter wheel: ZWO 7x2" EFW, Optolong LRGB and L-Pro Filters. Guiding equipment: guidescope: starguider 60/240 mm, guide camera: ZWO ASI 120mm mini. Total Integration Time: 10.5 h: 164x120” lights L+L-Pro, 50x120” lights R+L-Pro, 50x120” lights G+L-Pro and 50x120” lights B+L-Pro. Calibration images: 50 darks, 50 flats per filter. Softwares used: SharpCap 3.2, SGP 3.1, PHD2, Pixinsight 1.8.8 and Photoshop. English: Astrophotography of M20 nebula in LRGB technique. Cappellettiariel
