Astronomy Pictures

One thing thats got me discouraged in buying the E510 is the bulb function is limited to 8 minutes on these cameras. Why on earth would Olympus limit the bulb to 8 minutes???? Most everyone else has infinate control on the bulb function. But when I look at pictures taken with E510 or E500 vs. Canons XT or XTI cameras I see a big difference in how vivid the colors and sharpness is in the Olympus pictures. So that kinda why I want to stick with possibly gettiong a E510.

SO, Heres is my question. Does anyone with a Olympus DSLR camera take Astronomy pictures through their telescope? I know you can take multiple 2-3 minutes pictures then layer them together to get the color of nebulas desired in the shot. But I have no idea how to do this process or what photo editing program I would need to do this process. Anyone that has ever looked through a telescope knows when you look at most planets or nebulas all you see is gray planet or milky cloud and no color. Color takes much longer to show up in long exposure photos. So i'm wondering how the process works and what you have done to get awsome shots of planets or nebulas with you Olympus DSLR camera? Anyone have example pictures that they've done with their telescope? or even the star movement at night with setting up your camera and pointing it toward the north star and doing a long time exposure to capture the star move in the circular patern? School me on doing photos that appear to have been taken longer the 8 minute limit Olympus has put on these cameras...

For astronomy, you need as much light to the sensor as you can get, and it cannot move unless that is your intent. The earth and everything else you are trying to photograph are moving with respect to each other. A good lens on a tripod will get you part of the way there, but the best pictures are created with a star tracker guide. It is a device that when set up locks on to a bright star and uses it as a guide for the exposure. This works because they are distant enough that the scale of their movement will not disrupt the picture.

If you have ever got lost in the technical specifications of a certain telescope or camera, and wondered if it will actually perform well for astrophotography, you are not alone. You know the type of pictures you want to capture, but choosing the right equipment for your budget is where things get fuzzy.

The backyard setup shown below may seem a little complex at first, but it did not happen overnight. If you are passionate about astronomy and photographing objects in space, your progression and enjoyment in the hobby of astrophotography will last a lifetime. To review each piece of gear I use to capture images of space from my backyard, be sure to visit the astrophotography equipment page.

The type of camera used for deep-sky imaging is usually a DSLR, a dedicated CMOS sensor astronomy camera, or CCD (Charged coupled device). DSLR cameras are one of the best ways to get started in deep-sky astrophotography, as they are affordable and user-friendly.

A dedicated astronomy camera such as the ZWO ASI294MC Pro (pictured below) has features that can help you produce incredible long exposure images. These cameras have TEC (thermoelectric cooling) to help reduce a lot of the noise present in a single exposure.

Unlike a DSLR/mirrorless camera, a dedicated astronomy camera requires additional software to run the camera. The software allows you to set the exposure time and gain, and control important features such as the cooling temperature. Popular camera control options today include N.I.N.A. and the ASIAIR Plus.

Professional deep-sky imagers tend to use sensitive CCD cameras with a set of narrowband filters, but a regular DSLR camera is the perfect entry point into the hobby. There is some incredible work being done with DSLR cameras that rival much more expensive dedicated astronomy cameras.

In the example below, I compared stacked sets of 2-minute light frames with a dedicated astronomy camera. Even though dithering or dark frame subtraction was not used, you can clearly see that the noise is reduced as more exposure time is added to the final integration.

Astronomy Photographer of the Year is the largest international competition of astronomy photography in the world. Every year we showcase the best space photography from a global community of astrophotographers. These winning and shortlisted photos then go on display at the National Maritime Museum in our dedicated photography gallery space.

The Andromeda Galaxy is our Milky Way's closest spiral galactic neighbor, located about 2 million light-years away. Though visible as a faint smudge with the naked eye, the galaxy comes to life when viewed with basic observing equipment. Amateur astronomer Robert Gendler combined 40 gray-scale frames of the galaxy to create this beautiful image. Color came from previous images. Access to these tools, Nemiroff notes, allows amateurs to contribute scientifically valuable images to astronomy.

Each year, the Royal Observatory of Greenwich assembles a panel of art and astronomy experts as judges for the competition. This year, they received over 4,000 entires from 64 different countries. The nineteen photographs below are the official shortlist of final contenders.

Antonia Maury (1866-1952) was another educated woman, graduating from Vassar College in 1887 with honours in physics, philosophy and astronomy. She was also the late astrophotographer Henry Draper's niece, so her father wrote to Pickering, who was continuing Draper's work, and secured Maury a position among the Harvard Computers in 1889.

Henrietta Swan Leavitt (1868-1921) was an 1892 graduate of Radcliffe College, where she received a broad education that included philosophy, fine arts, Greek, geometry and, of course, astronomy. She was, by all accounts, a quiet and serious-minded woman, so when she went to work for Edward Charles Pickering in 1893, she threw herself into her work diligently.

Since almost all observational astronomy today uses photography, the term "astrophotography" usually refers to its use in amateur astronomy, seeking aesthetically pleasing images rather than scientific data. Amateurs use a wide range of special equipment and techniques.

Astronomical photography was one of the earliest types of scientific photography[1] and almost from its inception it diversified into subdisciplines that each have a specific goal including star cartography, astrometry, stellar classification, photometry, spectroscopy, polarimetry, and the discovery of astronomical objects such as asteroids, meteors, comets, variable stars, novae, and even unknown planets. These often require specialized equipment such as telescopes designed for precise imaging, for wide field of view (such as Schmidt cameras), or for work at specific wavelengths of light. Astronomical CCD cameras may cool the sensor to reduce thermal noise and to allow the detector to record images in other spectra such as in infrared astronomy. Specialized filters are also used to record images in specific wavelengths.

The conventional over-the-counter film has long been used for astrophotography. Film exposures range from seconds to over an hour. Commercially available color film stock is subject to reciprocity failure over long exposures, in which sensitivity to light of different wavelengths appears to drop off at different rates as the exposure time increases, leading to a color shift in the image and reduced sensitivity over all as a function of time. This is compensated for, or at least reduced, by cooling the film (see Cold camera photography). This can also be compensated for by using the same technique used in professional astronomy of taking photographs at different wavelengths that are then combined to create a correct color image. Since the film is much slower than digital sensors, tiny errors in tracking can be corrected without much noticeable effect on the final image. Film astrophotography is becoming less popular due to the lower ongoing costs, greater sensitivity, and the convenience of digital photography.

Astrophotographic hardware among non-professional astronomers varies widely since the photographers themselves range from general photographers shooting some form of aesthetically pleasing images to very serious amateur astronomers collecting data for scientific research. As a hobby, astrophotography has many challenges that have to be overcome that differ from conventional photography and from what is normally encountered in professional astronomy.

Here are some pictures I've taken with various telescopes throughout my career. Some of them were taken at Kitt Peak and Lawrence Livermore National Laboratory (need links) for research purposes while others were taken at the Stanford Student Observatory (need links) purely for fun. To download the full-resolution version, click on the link in the "Object" field. You may notice some strange artifacts in the images taken with the H1RG, H2RG, and H4RG HyViSI detectors. To get an explanation of what's going on there, see my thesis.

The competition is run by the Royal Observatory Greenwich, showcases the best astronomy photos that capture the beautiful and spectacular visions of the cosmos, the vast galaxies millions of light-years away, and the night sky taken much closer to home.

Runwei Xu and Binyu Want win young astronomy photographers of the year with "The Running Chicken Nebula," a hypnotic blend of swirling cosmic colors from the Running Chicken Nebula, IC2944. The young photographers captured this image using a 1,900 mm Newtonian telescope, over 5.5 hours of exposure. 006ab0faaa
