The Tuscan red & gray paint scheme, with gold accents, rolled debuted on Canadian Pacific in 1949. About 10 years later, in 1960, a modified version of the paint scheme was released featuring script lettering on the long hood. Jump forward another 60 years, and CP decided to revive the paint scheme on 5 rebuilt SD70ACU's in 2019. They look very good.
CP 2816 and the Final Spike Tour needed an additional diesel due to issues with one of the FP9's on Rich Mountain, and to help with upcoming grades in Mexico. When the train arrived in Shreveport, someone noticed CP 7013 nearby and realized its paint fit in perfectly with the special. They gave it an impromptu bath and added it to the train. Freshly washed, that script lettering looks really nice.

Загас мэгшдэггүйн учир
Нулимс нь далай юм байлгүй
Шувуу төөрдөггүйн учир
Өд нь тэнгэр юм байлгүй
Би унадаггүйн учир
Үсэг минь босоо юм байлгүй
Here is my completed image of the Eagle Nebula (M16) imaged with Sulphur, Hydrogen, and Oxygen narrowband filters. This false-color widefield image of the nebula represents the strong oxygen signal as cyan, hydrogen as yellow/orange, and the stronger sulphur signal as red. Naturally, this nebula is nearly all red in color, as hydrogen-alpha dominates the field. With selective filters and processing I have stretched the intensity of the Oiii and Sii to better represent where they lie in the nebula.

Acquisition:
Location: Flower Mound, TX for Ha(Bortle 7), Atoka, OK and Ft. Griffin State Historic Park, TX for Oiii and Sii(Bortle 3)
Dates: 5/12/18, 5/26/18, 5/27/18, 6/29/18, 6/30/18, 8/2/18, 8/3/18, 8/6/18
Gain: 200 Offset: 50
Camera temp: -10C
Sii: 36x600" Astrodon 3nm
Ha: 160x300" Astrodon 5nm
Oiii: 37x600" Astrodon 3nm
Total integration time: 25hr 30min
64x darks per calibration (master from library)
30x flats per calibration
200x bias per calibration (master from library)
Preprocessing:
Batch PreProcessing script to generate calibrated images
StarAlignment
LocalNormalization
ImageIntegration
DrizzleIntegration
DynamicCrop each master
DBE each master
Luminance Processing:
Duplicated the master Ha to use as the luminance
Deconvolution
TGV & MMT noise reduction (via Jon Rista's method)
HistogramTransformation bring to non-linear
Duplicated the image to create a starless version, using a starmask and several iterations of MMT and MT. Then pushed the faint nebulosity in the starless version using PixelMath expression: "1-(1-$T)*(1-$T)"
Combined the starless version with the image using PixelMath expression "F=0.4; (1-(1-$T)*(1-s)*F)+($T*~F)" followed by the same function but with F=0.2, (s=starless photo).
HDRMultiscaleTransform to reveal core
MultiscaleLinearTransform for sharpening
LocalHistogramEqualization
MMT and MT for star size reduction
MMT for noise reduction of the darker areas
Preparing separate Sii, Ha, and Oiii linear masters for tonemapping (applied to each master individually):
TGV & MMT noise reduction (via Jon Rista's method)
Removed stars via a StarMask and a few iterations of MMT and MT
Further removed background artifacts with an unmasked MMT
HistogramTransformation to bring to non-linear
HDRMultiscaleTransform to reveal core
Combined prepared Sii, Ha, and Oiii masters with ChannelCombination:
R: Sii
G: Ha
B: Oiii
Tonemap Processing:
Invert>SCNR green>Invert to remove magenta
Several a/b channel CurvesTransformations using ColorMasks to alter the colors to an aesthetically pleasing palette
CurvesTransformation for saturation
DBE to remove color bias in the corners
Combined Tonemap with Luminance using LRGBCombination
HistogramTransformation to stretch image slightly
UnsharpMask with a StarMask to harden up the soft stars a tad
CurvesTransformation for slight saturation
ACDNR for final noise reduction
Resampled to 40% for web posting
