Eta Carinae and "Gabriela Mistral" nebulas, Gem's Cluster Mosaic NGC3372/NGC3324/NGC3293 in Carina
This image is a 2 tiles mosaic, composed by two photographies taken at San Antonio de Areco, Buenos Aires, Argentina, the 3-24-2017 and the 4-29-2017.
The individual tiles are the Eta Carinae Nebula image and the "Gabriela Mistral" Nebula / Gem's Cluster image.
The total integration time for each tile was 2hs 45 min.
The used equipment setup: Newton GSO 200 F4 with GPU Comma Corrector, Canon 600D/T3i modified and refrigerated (sensor measured and regulated temperature 0°C), Astronomik CLS CCD filter, SkyWatcher NEQ6 mount, and homemade electronic focuser and anti-dew systems.
