This is the second target for my new wide-field setup, the North America and Pelican Complex. Both belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) show a rich and diverse structures filling the full 4×5 degree field of view. A perfect target for the ATIK 460EXm plus Asahi/Pentax Takumar 135mm combo.
Following my Ha mono version, this is now the full tri-color narrowband composite using 52 Ha, 30 OIII, and 24 SII exposures with 300 sec each. As usual, I could not decide which (false) color scheme I like more, therefore, I upload a selection. Make sure to look at the full-screen view.
