Astrofest Shots in Infrared (continued)

I've run out of room on the other thread, blame astrofest pristine clear skies for it, so I'm adding to the image collections here. Also found some old LUMs in raw so reprocessed some of the blends. The color balance is better and I could up the res significantly as a result. Check the big ones if you have the bandwidth, there's heaps of details.

Bit short of a mosaic on this one. Missed it by thaaaat much.

M16 - The Eagle Nebula

QHY9/FSQ106N on G11/Lodestar OAG and Astronomik 742nm IR filter - 42x300s.

[3336x2496 - 4.8MB] 1:1
[1920x1437 - 1.9MB] HD

Here's the standard blend IR IR/LUM LUM.
[3348x2504 - 7.8MB] 1:1
[1920x1436 - 3.4MB] HD

M17 - The Swan Nebula

QHY9/FSQ106N on G11/Lodestar OAG and Astronomik 742nm IR filter - 32x300s.

[3336x2496 - 4.8MB] 1:1
[1920x1437 - 1.9MB] HD

Here's the standard blend IR IR/LUM LUM.
[3348x2384 - 6.9MB] 1:1
[1920x1367 - 2.9MB] HD

Corona Australis

QHY9/FSQ106N on G11/Lodestar OAG and Astronomik 742nm IR filter - 15x300s.

[3336x2505 - 4.0MB] 1:1
[1920x1437 - 1.6MB] HD

Inverted palette on this one. Cool blue, hot yellow. Bit of moire right center field due to LUM subs from the SPSP 2016 not being dithered. Back then I wasn't dithering much.

Standard blend IR IR/LUM LUM.
[3348x2285 - 9.1MB] 1:1
[1920x1310 - 3.4MB] HD

M8 - The Lagoon Nebula

... and of course it is unaustralian to pass on without imaging M8.
QHY9/FSQ106N on G11/Lodestar OAG and Astronomik 742nm IR filter - 44x300s.

[3336x2505 - 5.1MB] 1:1
[1920x1437 - 2.1MB] HD

Unconventional blend IR IR/Sii Sii. Don't have a LUM for it but I had some decent Sii so I used it as a base for the color blend. Works well. Until I get some LUM. Might start shooting more Sii on other targets now. Looks cool against the milkyway backdrop as Sii is sparse. Almost like a thin translucent blue veil.
[3348x2477 - 8.3MB] 1:1
[1920x1421 - 3.7MB] HD

Enjoy the views.
