Description

Setting out to capture IC 289 was my biggest challenge ever at only 0.50 arc minutes. I wanted to see how much detail I could resolve through integration time and processing compared to what was done from the Mount Lemmon SkyCenter Schulman Telescope that is 32" in size:

I was pretty happy with my results. My image scale was 0.68"/pixel, but doubled the resolution in Photoshop before my final processing.

Formerly a star like our Sun, it is now just a cloud of ionized gas being pushed out into space by the remnants of the star’s core, visible as a small bright dot in the middle of the cloud. It was discovered by Lewis Swift in early September 1888. It lies close to the 10th magnitude star BD +60° 0631.

Description: I think I over processed my stars on the original version. It is so hard to get my stars right with my bortle sky scale 8 here. My stars always do some funky things.
