One of my less successful images. The stars streaking in the bottom left was because the center of the field of view moved when I inspected the images on the camera.

The famous Elephant Trunk Nebula (IC 1396) in the constellation Cepheus. This was captured in my backyard in Philadelphia using a 5nm Astrodon Hydrogen Alpha narrowband filter.

This is the second stage of the project to image the Elephant Trunk Nebula. The first stage was capturing the Ha/OIII Data with a dual band filter. This time, to catch the colour of the stars and the non HA/OIII data of the dust cloud, a full spectrum image was made. The series is not finished yet, more RGB data needs to be collected, but the series can show the progress of obtaining a final image nicely.
56 x 180 Seconds OSC = 168 Minutes Exposure, ca. 2,8 Hrs + 44 x 300 Seconds Ha/OIII dual Band = 220 minutes exposure, ca. 3,6 Hrs.

The Elephant's Trunk Nebula: 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.
Imaged July 2017 with hydrogen-alpha and oxygen-III filters through Stellarvue SV70t refractor and ZWO ASI1600 camera. 80 individual images at 3 minutes each (total of 4 hours integration each channel).

The Elephant Trunk Nebula is an active star forming region in the larger emission nebula IC1396.
Technicals:
This is a first light w/ the TMB92 and a Televue 0.8x FR/FF for 400-600mm scopes. It seems to do well, although I don't have the spacing perfected yet as shown by the stars in the corners. I'm quite pleased w/ this result. The f-ratio of the system is 4.4, giving a fast gathering of light. The contrast is improved compared w/ my last result on this object shown here with similar exposure time but on a f/6.25 doublet.

In the same way that dust is blown around by the wind here on Earth, space dust can be blown around by the wind and radiation from stars. This image of the Elephants Trunk nebula from NASAs Wide-field Survey Explorer, or WISE, shows clouds of dust and gas being pushed and eroded by a massive star. The bright trunk of the nebula near the center is an especially dense cloud holding up against the stars powerful radiation and stellar wind, like a windsock standing strong while the rest of the gas and dust gets broken up and swept away.
Elephant trunk is a term commonly used by astronomers for this type of structure. Similar structures can be found in many other nebulae, however this is the only nebula that uses the term in its moniker. More distant examples of elephant trunks can be seen in previously featured WISE images such as LBN 211.91-01.37 and the Soul nebula. Theyre all formed in basically the same way -- a nearby massive star (or cluster) emits vast amounts of ultraviolet radiation and stellar winds that clear out all of the gas and dust surrounding it, leaving behind only the most dense parts of the cloud. These dense portions then protect some of the gas downwind creating a trunk-like feature.
The culprit star here, HR8281, is located close the center of the image. Its one of the three bright blue stars near the upper left tip of the trunk that form a triangle about as wide as the glowing tip of the trunk. Of those three, its the uppermost one in the center. Its destructive effects on the surrounding nebula can be seen by the dark cavity its created, outlined by the brighter dust clouds encircling it. The entire nebula, also known as IC1396A, fills most of the field of view. Its located only 2,450 light-years away, quite close compared to other similar nebulae. The trunk itself is about 30 light-years long, while the full nebula stretches over 100 light-years across.
If you look closely at the tip of the elephant trunk you can see a small dark area, appearing as a sort of opening. This is a small void in the gas formed by a pair of new baby stars that recently formed in the dense cloud. Their radiation and wind is clearing out the nearby gas and dust, creating a smaller version of the same effect seen on a larger scale in the full image. The reddish stars scattered throughout the image are likely new stars still wrapped inside their dusty cocoons.
The colors used in this image represent specific wavelengths of infrared light. Blue and cyan (blue-green) represent light emitted at wavelengths of 3.4 and 4.6 microns, which is predominantly from stars. Green and red represent light from 12 and 22 microns, respectively, which is mostly emitted by dust.

This image is 53 light frames at 120 seconds a piece, 45 dark frames, 35 flat frames, and 40 bias frames. Images stacked in Deep Sky Stacker, and post processing done in Photoshop. Had to do a little burn/dodge to help make the darker regions pop out a bit more as the red from the nebula bled into the darker region. I may revisit this region later on this year.
Equipment:
Omni XLT 150 with CG-4 mount

My new attempt at IC1396... unfortunately, slightly out of focus. The elephant trunk is however visible this time at the top.
This is a total of about 100minutes of 2 minute exposures, unguided using a modded Canon 350D DSLR and a 200mm L-series f2.8 prime lens at f3.2. ISO was 800.

So far, this is about 4 hours of Ha data with An Atik 414 and a 102mm apo. I thought the red tones really made the bright ionized gas POP. Cant wait to get some OIII data on this one.
I captured this image of the Elephant's Trunk nebula using a Takahashi TSA-120 telescope, a 3nm narrowband filter for H-alpha and OIII wavelengths, and an ASI533MC camera. This photo is the product of a total of 35-hour exposures, revealing intricate details and the nebula's delicate tendrils and vibrant hues.
