Astrophotography

Hearth Nebula - H-alpha version After sime time I managed to get online again. I "attacked" this time this object again, I have imaged this one with a Kodak 1602E based camera. Technical data: Exposures 22x900 sec Filter Halpha 6 nm from Astrodon Optics: TS ED APO 90/500 mm Imager: QHY9M at -30°C Mount: EQ-6 with EQMD Guider: Atik 16IC Image is corrected using darks, flats and bias using DeepSkyStacker, the result was imported in PS and some minor adjustments have been done (mainly curves and a little sharpening).

Somehow a second run, I have managed to get the lights in December but only now to process them.
