A new project, The Cat's Eye Nebula

At the same night, when I finalized the Tulip Nebula, I took first frames for my next target.

Cat's Eye nebula is a small, complex structured, Planetary nebula in constellation Drago.

In this first version, only H-alpha light is exposed. There is strong O-III component in its halo.

Doe its small angular size, good seeing is needed to show any internal details in nebula's core.

Seeing was really bad and I just tryed to capture H-a for outer halo.

However, there was some details in bright core as well.
