Description

This is a very preliminary edit. A single hour of integration for the background, and about 30 minutes each for the various core images. Currently an HDRComposition of 3 sequences: 300s, 150s, 90s. Simply processed to see what detail was captured...turned out there was quite a lot.

The Astronomik CLS-XL clipin filter for the 5D III causes a lot of problems due to it's design, and as such, I believe instead of continuing to get integration time with that filter for these sequences, I am simply going to restart with a new filter (probably an IDAS LPS-D1 52mm), with 420s, 210s, 90s and 15s exposures for HDRCompsition.
