About this image

NGC 1514 is a planetary nebula located in the constellation Taurus, near the border with Perseus.

Equipment used:- Stock Canon 40D mounted at Prime Focus on Meade LX-90 8” telescope (focal ratio f/10 focal length 2,000mm) with a 0.63x Focal Reducer (giving an effective focal ratio of f/6.3 and focal length of 1,279mm) fitted to its field tripod by an equatorial wedge. Telescope Polar Aligned. LX-90 Periodic Error Correction enabled. Dew Removal straps fitted to telescope and operating. Telescope driven but unguided. Telescope and camera powered by Mains Power.

Exposure details:- Four sub-exposures each 3 minutes taken at ISO1600. Ambient temperature 2 degrees Celsius.

Processing details:- After quality control 3 sub-exposures calibrated with Dark, Flat-field and Bias Master frames before being combined and processed in Images Plus. Image sharpened and rotated in Photoshop CS5 so that North is at the top. Noise reduction performed in Noise Ninja. Image cropped to give field of view 23 arc minutes x 15 arc minutes.

Narrative description:- One day after New Moon, the Moon had already set before imaging commenced. The weather was calm, clear and very cold with heavy dew. A cloud sheet moved up from the south bringing the session to a premature end.
