Deep Sky Objects: Hydrus and Tucana

Hydrus and Tucana are Southern constellations. Away from the Milky Way, they share the Galaxy called the Smaller Magellanic Cloud. In Tuscana are a number of very faint galaxies.

Small Magellanic Cloud (top center), Bright cluster 47 Tuc (bottom center)


Realising a detailed image of this scene is difficult. The galaxy is distant while the core of the cluster is bright. In a single image i can image either the center or the exterior of the cluster in greater detail (by modifying ISO). The answer is to use stacking software (DeepSkyStacker) and to shoot multiple frames.
