Description

Its been a boring Winter and early Spring here in the Pacific NW, so I downloaded some Hubble data. Each RGB and Ha image is about 400MB and the combined XISF file in PixInsight was 1.2GB. It almost crashed my 24Gb RamDrive with all the copies used by the Swap Files. No matter what I do the JPG really clips the background to black. In the XISF file, you can see a BUNCH of galaxies. Some of them also look like there is gravitational lensing happening. Pretty cool
