The Elephant's Trunk nebula is a concentration of gas and dust located in the constellation Cepheus, ~2,400 light years away. The column of nebulous gas cloud is being ionized and lit up by a massive star inside (picture it inside the round section at the top of the trunk), and is thought to be a site of new star formation.

Personally, I like all the dusty, smoky regions surrounding it.

I have already attempted this one, but wasn't too happy with the noisiness and colour balance in my first try. So here we are again, this time with much more Hydrogen alpha data (collected 5+ hours, but only used about 3.5 hours worth thanks to clouds and haze).

Object Details:

Globular cluster NGC 6712 lies about 22,500 light-years from Earth, contains approximately 94,000 stars and is estimated to be about 10 billion years old. Shining at magnitude 8.6 and having an apparent diameter of just over 7 arc-minutes, it (and IC 1295) can be found in the constellation of Scutum.

Planetary nebula IC 1295 is (by comparison a 'mere') 3,300 light-years distant. Glowing at magnitude 12 it spans just 1.7 x 1.4 arc-minutes in our sky.

Image Details: The attached was taken by Jay Edwards at the HomCav Observatory on the evening of July 26, 2019 using an 8-inch, f/7 Criterion newtonian reflector and a Canon 700D DSLR tracked on a Losmandy G-11 mount running a Gemini 2 control system. This in turn was guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor.

This is my first attempt at imaging these object, and as such is a test consisting of a (relatively speaking) very short stack totaling only 45 minutes of exposure (not including darks, flats & bias frames).

Although I was fairly pleased with the result, given the large difference in brightness between the core of the globular cluster and the outer regions of the planetary nebula, I look forward to trying an HDR-like approach on these objects in the future in an attempt to bring out additional details in the nebula's outer regions while simultaneously preventing the globular's core from overexposing.

Stacked in DeepSkyStacker and processed using PixInsight and PaintShopPro, as presented here in nearly 'full frame' (having only been cropped slightly to remove the minor shifts between frames), re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.

This is a 2 x 2 mosaic of tracked 90 sec. exposures for the sky, and untracked exposures for the trees. I stacked 2 exposures for each sky panel to reduce noise, and then combined the 4 panels manually in GIMP.

I was aiming to capture the Cygnus nebulae on the right; the inclusion of the Heart and Soul Nebulae and the Double Cluster in Perseus on the left was a happy accident. The light trail at the top is an airplane.

It's a huge mess if you pixel peep, but I like the overall impression, and am glad I came away with something for the lost sleep, and considering that I forgot the part to attach my camera to my ballhead and had to use rubber bands.

I decided to take advantage of the new moon, drag my telescope, and do some astrophotography last night...even with the time change and losing an hour of sleep. I'd say the bit of sleepiness today was worth it to get back into Astro and get this shot of my first time imaging this nebula!

The Rosette Nebula (NGC 2237) is 65 light-years across and 5,500 light-years away from Earth. It is visible in the sky between the constellations Gemini and Orion, in the head of the constellation Monoceros.

I polar aligned my mount using SharpCap Pro. My Sony a7SIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and the outputted TIFF file was brought into PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.

A planetary nebula is formed when a star puffs off its outer layers and these expand into space. They are not related to planets, but rather looked like planets to early telescope users - hence the name.

This is an image from April this year, but as with so many of my deep sky work I've included frames taken in previous sessions to reduce noise and therefore to help show subtler details.

29 x 1-minute unguided frames at ISO 6400 (new data) and 15 x 5-minute manually-guided frames at ISO 1600 (older data from 2013 and 2014). Modified EOS 600D & Revelation 12" f/4 Newtonian reflector telescope.

Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise and light pollution colour gradients reduced in CyberLink PhotoDirector. I also used Noel Carboni's astronomy tools in Photoshop Elements to reduce the prominence of the stars (which otherwise dominate after stretching the contrast).

The galaxy Messier 100, a.k.a. the "Blowdryer Galaxy" (who thinks up these names?) is one of the largest and brightest members of the Virgo Cluster of galaxies. It is located in the constellation Coma Berenices. Messier 100 is an example of a "grand design" intermediate spiral galaxy. It is approximately 55 million light-years] distant from Earth and has a diameter of 107,000 light years.

Messier 100 is considered a starburst galaxy, with the strongest star formation activity concentrated in its center - where intense star formation has been underway for about 500 million years.

The image also captures several other galaxies of the Virgo Cluster. To the left is the spindle shaped NGC 4312; it too is a spiral galaxy, but we view it nearly edge on. It shows us a brighter nucleus, a dimmer surrounding disk, and an outer rim that blends into the darkness of interstellar space. At the 12:00 position relative to Messier 100 is a small fuzzy ball, the elliptical galaxy NGC 4328. At the 02:30 position relative to Messier 100 is another elliptical galaxy, NGC 4322. NGC 4322 appears to be connected to Messier 100 by a faint glowing stream. These are probably stars and dust/gas clouds that have been wrenched from the two galaxies by the gravitational tides of their interaction. Similar streamers of stars and gas can be seen between our own Milky Way Galaxy and the two satellite galaxies, the Large and the Small Magellanic Clouds. If you look around the image, you might find a few other galaxies - I have not been able to identify them yet; I will tag more as I learn their names. This area of the sky abounds with them!

I was having fun observing this galaxy group, up until the local temperature dropped to the dew point. I found myself in need of a way to de-fog my lenses. Not having a battery powered blowdryer... HEY! THAT'S WHERE THIS GALAXY'S NICKNAME CAME FROM!

The winter doesn't end without photographing the famed Messier 42.

The image shows the Great Orion Nebula and the De Mairan's Nebula.

On May 2nd, 2014, I decided to take some photographs of Galaxy Messier 101 (or M101) in the constellation Ursa Major. It is also more commonly known as the Pinwheel Galaxy. I noticed that in the Starry Nights Pro software program that there were a number of New General Catalog (NGC) objects associated with this galaxy, especially in the spiral arms. The 29 minute stacked exposure is my first attempt to examine some of these associated NGC objects that are part of M101. I plan on adding addtional time to this as weather permits.

I stacked the original 10 RAW frames from this photo with the 5 RAW frames from this one (a total of 51 minutes' exposition time), just to see what would come out.

Pretty nice results, I think - The bright stars stand out better without looking hazy, and Barnard's Loop and the Horsehead Nebula are more visible too.

- www.kevin-palmer.com - There are a lot of astronomical objects which have names that don't seem to fit. But this object strongly resembles its name: the California Nebula. It is located in the constellation Perseus and is very difficult to see even with a telescope because of its low surface brightness. The nebula is made up of hydrogen gas that glows because of the radiation from the nearby star Menkib. Also known as NGC 1499, this nebula covers roughly as much sky as 5 full moons. On the right side of the image dark nebula can be seen. It is made up of insterstellar clouds of dust so thick that it obscures the light of stars behind it.

This was shot with a Takumar 135mm f2.5 lens at f4, iso 1600. It is a stack of of 20 2.5 minute frames, plus 8 darks, and 8 bias frames. An iOptron Skytracker was used to track the stars.

This is my first time combining multiple nights of data and also the first time I've done longer then 300 second exposures. This image has been tricky to process and I'll likely go back and try again. Some of the stars in my stacked image show some noticeable trailing, but that isn't the case with most of my subs. The stars aren't quite pin point in the subs either though. I'm thinking its some refraction or other type of aberration from the extender. That thing is nice to have for the extra focal length, but it really isn't the best and kind of kills the great optics of the Canon 70-200 f/2.8L. I'm going to try stacking the image in PixInsight. Other's have suggested I use that instead of DeepSkyStacker as it's suppose to do a better job, but I haven't had success with it in the past. Worth another shot I suppose. Still, pretty pleased with this image. I know there is a lot of Ha in this region and that can be difficult to pickup with a stock DSLR so I think I did a pretty good job.

Ha channel only.

Nights have been mostly cloudy and rainy these past few weeks, hope to get some clear skies soon to capture the remaining Oiii and Sii data.

The Crab Nebula (M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.

At an apparent magnitude of 8.4, comparable to that of Saturn's moon Titan, it is not visible to the naked eye but can be made out using binoculars under favourable conditions. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6,500 light years from Earth. It has a diameter of 11 light years.

Just for grins, I dug up all the 30-second M42 frames I've taken through my 80ED and fed all 120 light frames to DeepSkyStacker to see what I detail I could pull out. Looks like quite a bit. There are several seams visible on the right side of the photo where coverage was incomplete. I didn't entirely escape the red stripe problem either...
