Observations in the H Band (1.625µm)

The core of the Trapezium cluster in the heart of the Orion nebulae observed in the astronomical H band (1.625µm) on October, 24 2014 at the Cassegrain focus of the 1 meter Omicron telescope of the C2PU facility (Observatoire de la Côte d'Azur).

All the images were taken at 1,625nm.

The planet is about 20 times farther away from the sun than Earth. Its apparent diameter on this image is about 2.9". Surface inhomogeneities are caused by clouds in the atmosphere of Uranus.

The core of the Trapezium cluster in the heart of the Orion nebulae observed in the astronomical H band (1.625µm) on October, 24 2014 at the Cassegrain focus of the 1 meter Omicron telescope of the C2PU facility (Observatoire de la Côte d'Azur). This region of the sky contains many young stars formed in that dust-rich environment. Stellar components of this open cluster are better observed at infrared wavelengths because of the lower absorption of the dust. The faintest stars are about H=13 magnitude. Stack of 4000 shift-and-added, 15ms exposure frames.
