Description

The Cat's Eye Nebula in HDR to expose the detail in the inner core that is usually blown out by the very bright star located there.

This has been particularly challenging as it is tiny and I'm using a 550mm focal length. I captured a LOT of 600s, 60s and 6s exposures to compensate and drizzled 2x to get some more resolution and cropped fairly heavily. Using a refractor does have the advantage of avoiding the diffraction spikes from that bright central area, but I think I need a much longer focal length to do this one justice.

PixInsight was used to stack, stretch and very lightly process, with the HDR merging and noise reduction performed in Photoshop.
