New 100% urban image with the Askar 140 APO
The IC 5070 nebula, better known as the Pelican Nebula, is a fascinating region of the night sky located in the Cygnus constellation, approximately 1,800 light-years from Earth. It is part of a vast complex of gas and dust clouds associated with the North America Nebula (NGC 7000). These two nebulae are separated by a dark band of interstellar dust, but they are part of the same giant molecular cloud.
This is my first test in SHO with this telescope, combining the L Ultimate HO filter and the Altair SO filter. The details are pretty crazy, I'm really happy with this telescope.
Taken over 5 nights (3 in HO and 3 in SO)
Here is a diagram of the process for taking this kind of image with a colour camera in image 3
