Astrophotography with Canon EOS. Astrophotography is the imaging of celestial objects such as the Sun, Moon, planets, comets, stars, clusters, nebulae and galaxies. Astrophotography captures the beauty and majesty of the night sky and wonders of the universe. Canon DSLRs are amazingly versatile for astrophotography. We can shoot long exposures of deep-sky objects at high ISOs because Canon CMOS sensors are remarkably sensitive and have exceptionally low noise. We can also use them to do time-lapse photography of the heavens, and even use the high-definition video modes for high-resolution planetary photography.
We can get started in astrophotography with really simple equipment – just a camera and lens on a tripod. With longer focal lengths on an equatorial tracking mount, we can piggyback a 50mm lens with a ball-and-socket head on top of a telescope and shoot large areas of star clouds and dark nebulae. Special Considerations for Deep-Sky Astrophotograph Image Trailing The Darkness of the Night Sky White Balance Focus. ASTROTIPS. Celestial Objects. Astronomers don't know why Jupiter's iconic Great Red Spot has been gradually shrinking since the 1800s — or why the downsizing has accelerated during the past two years. Thanks to the planet's immensity, seeing Jupiter through a telescope can be very satisfying. Its two main cloud belts appear in most any backyard setup, and...
Photographer firstname.lastname@example.org Date/Time of photo April 15, 2014 Uranus and Neptune are easy to find with the aid of the charts in this article. This star-studded pool of misty light provides a feast for observers. Explore the Moon with binoculars or a telescope. The King of Planets reached opposition in the first half of January but it's still big and bright, a captivating sight no matter how you look at it. The two brightest asteroids are very close to each other in the sky in 2014, fitting in a single field of view through binoculars and some telescopes. Sky & Telescope predicts that 2014's best meteor shower won't be one of the traditional displays. Camera Only Astrophotography. Astrophotography – Without a Telescope Author: RalphC Published: December 29th, 2011 Milky Way, Credit: Ralph Clements By Ralph O.
Clements When I was invited to write about this subject for Astronomysource.com, I must say I was flattered and a bit flabbergasted too, as I do not consider myself an expert on the subject, nor a writer by any means, but just a guy who likes to go out at night and take pictures of the sky. I took that thing out in the country and set it up (completely wrong, I now understand) and as darkness approached, held my point-and-shoot camera up to the eyepiece and took a picture of Venus.
“Camera Only” Images I do take images with newer telescopes and a decent equatorial mount which I have acquired since. Equipment My research indicated that Canon cameras are preferred for astrophotography and the T1i is what I use for everything.

Deep Sky Stacker. IMPORTANT: This is a living document written for a small group of astronomers learning together at the same pace and. It is not meant as a definitive guide, I am sure there are others out there that achieve that. This will be expanded upon the more "we" become comfortable with and learn more of what this program can do. DeepSkyStacker (DSS) - a beginners guide This is a basic tutorial to enable you to create a .tif file containing as much image information as possible from a stacked set of raw images. This will then be processed using follow on software such as Adobe Photoshop, Adobe Lightroom even Photo Plus 10 which by the way comes free with January's Sky at Night magazine.
Before starting this tutorial it is assumed you already have created a set of subs/lights and calibration frames (Dark Frames, Flat Frames, Bias Frames and even Dark Flat frames). This is how my hard drive is set up complete with a temporary folder so DSS can strut it's funky stuff ! Ok on to the <Light> tab. .... DeepSkyStacker - Free. Image Stacker. Astrophotography. Favorite Software Tools. Backyard EOS Image capture only: $ 24.00 This is a pretty slick image capture software that is specically designed for Canon EOS cameras. It has some nifty features such as: Frame & Focus: Measures and displays star size permitting fine focusing Integrated with PHD Guiding software and permits "dithering".
Dithering is a technique used by the Pros that shits the mount a few pixels between each image and prevents "hot pixels" from appearing in the final "stacked" image. This software is perfect for the astrophotography beginer and at ony $ 24.00 it is a bargain! The only downside is that it does NOT include any post-image-capture features such as calibration (darks, bias, flats), align and stack. Images Plus - Image capture, post-processing $ 230.00 Images Plus is likely the most popular software choice for beginners and intermediate astrophotographers. Nebulosity - Image capture, post-processing $ 60.00 Nebulosity has most of the features as ImagesPlus but is not quite as slick.
Star Trails app. What does it do? You can load the Images and optionally some dark.frames (will be averaged and subtracted automatically if exist). If there are some images you don’t want you can uncheck them. Zooming into the images is done with the mouse-wheelOptionally you can average some of the images to get a better signal to noise ratio for the sky-background or the foreground. This averaged image is brightend internally and at the end of the processing blended in "lighten"-mode into the resulting image The resulting image can be saved in Jpeg,TIFF or BMP format Another feature is the creation of a time-lapse movie as an "AVI"-fileOf course this feature can be used to create any time lapse movie, not only starmovies.. System requirements: As it is developed in C# you need the Microsoft .NET framework installed.

Several people asked me to post a simple tutorial on how I took some night sky pictures.
I am not an astrophotographer in any way, shape or form, nor do I have any expensive equipment. I simply read several tutorials, picked a dark spot on the beach and tried to do my best. Anyway, here is how I did it. 1. You need a camera that has manual exposure mode. You will also need a remote control or a shutter release cable in order to minimize shaking the camera when taking the pictures. You will definitely need a tripod 2. The darker the place, the better it is. 3. First, try to use a lens with a large aperture. Next, set your camera at a high ISO. Finally, in order to avoid the star trail (that is avoiding capturing the movement of the stars as the earth rotates) you have to use the RULE of 600 which is very easy: Divide 600 by the focal length of the lens you are using. 4. 5.
