The IC1396 emission nebula in Cepheus, home to the famous Elephant’s Trunk Nebula. It is a large emissions nebula with stunning inlays of dust clouds absorbing most of the lights. The total size of the IC1396 complex corresponds to about 10 times the full moon.

This is a straight Ha monochrome image constructed from 15 exposures with 600 sec each, a total of 2.5 hours of exposure. Using my wide-field setup with the Asahi/Pentax Takumar 135mm f/2.5 with the ATIK 460EXm. Taken from the balcony of my house in the light-polluted Frankfurt area – Bortle class 7 (red zone). This is the “first-light” for my self-constructed wooden pier, which worked like a charm. Guiding rms-errors of the AZ-EQ6 during the 10 min exposures were on the order of 0.4 arcsec.

Make sure to look at this image in full-size view.
