Description

The Cat's Eye Nebula,really hard to process because of the bright core and the dimmer outside,witch is most H-alpha and O3.

I did subs of 120 second at unity gain for the outside,and 2 seconds for the core.

to bad astro pixel processor wont register them,because it dont have stars to see then.

i will try to do it in Pixinsight with a hdr image.

In the O3 image you can see the sensor of the Asi 1600mm,the clear glass have reflection.

to bad ZWO ASi still dont make a good clear glass for the 1600mm.

Adding the raw data too and a crop.
