The colour gradient is caused by light pollution, which almost washes out this part of the sky from where I am.
It's definitely globular cluster season, at least from the heavily obstructed skies of my back garden!

From the National Bridge website:
The beauty of the night sky, the lack of light pollution, and the National Park Service commitment to night skies as a natural resource, led the International Dark-Sky Association this spring to designate Natural Bridges National Monument as the world’s first International Dark Sky Park.
Natural Bridges is one of the darkest national parks in the country according to a comprehensive study of night sky quality conducted by the National Park Service.
Just how dark is it? “It’s the only Bortle class 2 sky they’ve documented,” said Chris Luginbuhl of the U.S. Naval Observatory in Flagstaff, Arizona., and a board member of the International Dark-Sky Association. “In plain English that means it’s the darkest or starriest sky they’ve seen while doing these reviews. The Bortle system is a 10-level scale with one and two being the darkest skies and 10 having the most light pollution.”

I got outside with the telescope over the weekend, albeit only briefly. I took the opportunity to finally image M45, something I'd not gotten round to previously. I wasn't really in the mood for it, and unfortunately that led to me taking some shortcuts and the final image suffered somewhat because it.
I didn't accurately level or polar align the mount, so in the 6 minute-long exposures I ended up taking, there was some rotation of the field, so the stars towards the edge of the image were obviously elongated. The image above is significantly cropped from the full image, so thankfully it's not noticeable. Still, I intend to re-visit this target in the future!

This is a semi-narrowband composition of the Flaming Star Nebula (IC405) and IC410. Since I use a full-spectrum DSLR, I used an Improved DGM NPB filter which allows through the spectrum lines of Hb (486nm) and both Oiii (495.9nm + 500.7nm) in one passband, and Ha (656.3nm) in a second 10nm-wide passband. This allows for decently color-balanced results to start with when using a full-spectrum sensor. I split the raw output stack from DSS into RGB channels (R being virtually all Ha), processed them separately in StarTools, created a synthetic luminance frame, then added the color back in using a bi-color approach with Ha as red and a blended G+B frame as blue, letting StarTools interpolate green.
Shot using self-modded full spectrum Nikon D5100 through Orion ED80 and CCDT67 reducer, on iOptron iEQ30 Pro mount. Used the Improved DGM NPB filter by Omega Optical along with the UV/IR cut filter by Optolong. Guided and dithered using Metaguide. Stacked in DeepSkyStacker, processed in StarTools. Used GIMP 2.9.3 to split RGB channels, and Noiseware for final denoising.

I took this photo from inside my house out of my bedroom window. It was -32C outside. I could not polar align the mount so I just guessed where the celestial pole was. Being new to astrophotography (I believe I have only a dozen processed pics) I cannot overstate how enjoyable it is to use a barndoor mount. I do not have a big budget and am saving for a telescope for astrophotography. I have a good camera with the cheap lens, add a couple of pieces of wood with a screw and I am amazed at what can be achieved. Anyone that cannot afford a good mount for widefield photography should build this type of mount. Even with a 300mm lens you can barely detect any star trails. I have modified my barndoor. Just like with a telescope, the mount needs to be sturdy, Any movement will ruin the picture. Rather then use a photo tripod (which was just to shaky) I screwed it directly onto a small table. I also made it so that I can change the angle of the axis incase I cannot find any flat ground. I just use a level to ensure it is somewhat level. I have downloaded a new pic.

Last weekend was a bright morning, seeing was not all that good, but I had a go at M57, The Ring nebula. Funny when the world around you wakes up. Started setting up at 03:00 started shooting at around 4:00. Used Vega as a guiding star, since guiding worked even when most of the stars where not there anymore.

No guiding, and I didn't get my mount spot on, so this is is made up of 14 shots, 10 seconds each at various ISOs, and my first go with DeepSkyStacker. So much to learn!
The Large and Small Magellanic Clouds, which are satellite galaxies of the Milky Way. This image was made by stacking 15 x 15 second exposures (plus 6 x dark exposures) taken with the 6D and EF 35mm f/2 lens at f/2.8 and 6400 iso, using DeepSkyStacker.
Well past its best here, but still showing the wide dust tail and long ion tail - the latter is faint but can be seen heading right out of the frame in the 10 o'clock position.

The Crab Nebula is the remnant from the supernova observed by Chinese astronomers in the year 1054. At it's center is a neutron star roughly the mass of the sun, but squished down to the size of a city.
29x 30 second exposures shot with a Canon T1i DSLR at ISO1600 on a 190mm F5.3 Skywatcher Maksutov Newtonian telescope. 14.5 minutes total exposure time.
I shot 54x 30 second exposures, and tossed out nearly half of them due to my unsteady LXD75 mount not tracking the stars sufficiently.
It was shot using the camera's long exposure dark frame noise reduction. I need to shoot some flat frames to remove the vignetting.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across.

M102 in Draco. There is some controversy over whether Messier actually observed this galaxy or it was an accidental duplication of M101.
This tiny galaxy is actually a spectacular edge-on galaxy with a magnificent dust lane as seen in professional images. I really only took this image as it's a Messier object I haven't imaged before, it's not very exciting at this scale!
