Description: This image of the Elephant’s Trunk Nebula IC 1396 was developed from 37x300s subs or 3.08 hours of total exposure time. A dual bandpass integrated image was first separated into Starless and Stars only images. The Starless image was split into its RGB components, which were individually boosted as appropriate, followed by the application of appropriate weighting factors to the individual RGB channels, further followed by LRGB Combination. The resulting image was then recombined with the Stars only image the result of which was post processed with various color masks using Curves Transformation to generate a final image.

Processing Software: Pixinsight
Processing Steps:
Preprocessing:
I preprocessed 37x300s subs (= 3.08 hours) in Pixinsight to get an integrated image using the following process steps: Image Calibration > Cosmetic Correction > Subframe Selector > Debayer > Select Reference Star and do a Star Align > Image Integration.
Linear Postprocessing:
Dynamic Crop > Dynamic Background Extractor (doing subtraction to remove light pollution gradients and division for flat field correction) > Background Neutralization > Color Calibration > Blur Xterminator > Noise Xterminator.
Nonlinear Postprocessing and additional steps:
Histogram Transformation > Star Xterminator to create Starless and Stars Only Images.
Starless Image > Noise Xterminator > Local Histogram Equalization > Multiscale Median Transform > Curves Transformation to boost O(III) and H-alpha signals > Split RGB channels > Create new green and blue channels > Boosted the channels as appropriate > LRGB Combination > Curves Transformation using various color masks.
Stars Only Image > Morphological transformation.
Pixel Math to combine the Starless Image with the Stars Only Image to get a Rejoined Image.
Rejoined Image > Dark Structure Enhancement > Topaz AI.
Pixel Math to combine the non-AI Rejoined Image with the Topaz AI Image to get a final image.
Out for a morning walk before it gets too blazing hot. What first caught my attention about this tree trunk was that I thought someone emptied a can of garbonzo beans - it wasn't, but is some kind of seed. Now that I look at the image I see a lot more of the finer details that make up the trunk.

There was a good mixture of traffic in the consist of the SBB Cargo morning trunk service 60065 from Lausanne Triage to Basel RB recorded in the care of Class Re 420 [4/4''] 420 306 near Ependes, Vaud.

Thai the elephant bull was puting his trunk on the forhead of a female. Sometimes the behaviour of elephants is fascinating!
The Elephant's Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.

For an instant it's not 2020. This train is not a foreign Z768. CN is in Canada. Grand Trunk runs the show. And as quick as it started, it's over. CN E260 continues to crawl by, but no more cars say GT. The Elsdon Sub is now owned and maintained by CSX. As much as I'd have loved to see the GT in full, I get these little moments and reality goes away, although only for an instant.

i was taken photos to this truck in Hackensack river in teaneck,NJ. for my surprise i did not see in first site the two little turtle on the trunck. Beautiful they was geting warm with the sun of april......
There are so many muscles in the trunk (over 40,000) it takes young elephants quite a while to work out how to use it properly.
I am suddenly getting lots of view on this picture, can someone viewing it let me know where you are linking from please? 26th April 2013
The new Smart Hybrids for trunk route 50 are now starting to enter service, the first being 6902 and 6903. Carrying the smart new branding that is being introduced on these, 6902 shines its way up the Alcester Road to Maypole, with a Druids Heath bound 50. Yardley Wood are receiving 6893-6914 & 6943/4 to upgrade the 50 to Platinum status. Pensnett, Coventry and Birmingham Central also take shares of the large 2018 batch, for routes 9/X10 (PN), 11s/12X (CV) and X70 (BC). The branding is similar to the West Midlands Bus style, featuring blue Diamonds before the advert frames, but the route is not set to undergo such treatment that the 31, 32, 42 and 43 in the Black Country have

Captured this ivy covered window with tree reflection with the iPhone, at Ridge Hill Reservation, Needham Mass. while traveling last weekend.
Was a super bright day, was hard to take photos with the phone unless you were in some kind of shaded area. I kept thinking I needed a front and back lens hood for the phone.

For me, the locomotive that will always be synonymous with the Grand Trunk Western will be their distinctive GP9Rs. In the late 1980s, the GTW decided to rebuild a portion of its aging GP9 fleet, which even then was the backbone of the Trunk's fleet, into modern GP9-equivalents. Original GTW units, along with some that had been reassigned from the Central Vermont and Grand Trunk Railways, were selected to be rebuilt. It is not known if there was any criteria for selecting which units would be rebuilt and which would not, or if they were simply chosen at random. The work would be done at the GTW's own shop in Battle Creek, MI, which would prove to be the last major project the shop would undertake before closing in the mid 1990s. The original cabs and noses were cut off the selected units, and new cabs and noses fabricated by VMV in Paducah, KY were installed. The units also had a complete rewire along with an engine overhaul, receiving EMD 645 power assemblies for their existing 567 engines. In addition, any incoming GP9s that had older 24 schedule air brakes were upgraded to the more modern 26 schedule. The first few units were completed in 1989, and GTW continued rebuilding them at a steady pace until 36 were completed by the end of 1993. The GTW wanted to get another 20 years out of them, and some of the fleet still runs for CN as of 2024, a testament to the work done by Battle Creek!
GP9R #4624 is seen leading what was probably L500 from Flint around the High Wye at Durand back in 2006. Today it works for the Carolina Coastal Railway.
Trick or treating has become less and less popular recently. Many neighborhoods, schools, and church groups instead of "trunk or treat" events where everyone gets together in a parking lot and decorates the back of their cars. Then kids walk past all the cars with their bags asking for candy. This is the first year our neighborhood has done a trunk or treat event in the local church parking lot and pictured are Jessica and Kellie dressed up and posing in front of our decorated car. Not sure what this means for the future of trick or treating in our neighborhood.

This is the current Primary class Kellie and I teach at church. We showed up in the church parking lot dressed as Mary Poppins and Burt - thanks to Kellie. Out of five kids in our class, we had two Pikachus.

The Elephant's Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the west of IC 1396A.

Wheeling & Lake Erie rolls into Bellevue behind a former Grand Trunk Western SD40 and a former Rio Grande GP35. #4000 has since been rebuilt into an SD40-3, losing its CN colors in the process. It was built in 1970 as GTW #5920.
