Description

... Sauron's Eye is watching!

75hrs data gathered over 2 months from Melbourne, Australia. (of which 64 hrs made the final cut).
Pushed the data pretty hard to get the outer chevrons & fiiigree details to seperate from the LP at my inner suburban location, so there's some noise present to maintain the signal!

30hrs 3nm Ha 1800 secs
30Hrs 3nm Ha Bin x 2 1200 secs
11 Hrs O3 1800 secs
1hr each RG & B 120secs

Wanted to show the O3 eye structures in the iris, so plenty of masking used in PS to balance the Ha/O3 present.

Big project - hopefully finished now!

Thanks for looking, C&C welcome :)

C

This version has very little noise reduction, so it has more detail, but more noise too!

D

Tried Topaz Noise reduction - works well!

E

Sharpened LUM layer - rebalanced noise vs. NR with Topaz
