Astrophotography Chapter 5

Long-Exposure Prime Focus Astrophotography
This is considered by many to represent the highest level one can achieve in astrophotography. The allure is that almost any deep sky object can be photographed, and when done well, yields astonishing results. If you pause for a moment and think about the most amazing astrophotos you have ever seen, you will almost certainly be envisioning long-exposure prime focus images. Perhaps the most famous of all is the Hubble Deep Field image, a photograph taken at the prime focus position of the Hubble Space Telescope that had a total exposure of over 100 hours!
Sky-Watcher Telescopes is very pleased to offer a variety of premium mounts and telescopes that have enabled many people to enjoy great success in photographing nebulae, star clusters and galaxies using prime focus techniques. We offer the hugely popular EQ6 and HEQ5 SynScan mounts in both Standard and Pro Series. These high precision computerized mounts can automatically point your telescope to over 14,000 objects in the standard data base, and when connected to a computer with suitable planetarium software they can point at virtually any known object.
For astrophotography the SynScan mounts can’t be beaten. They are capable of tracking the sky with errors limited to a few millionths of a circle. Moreover, they are equipped with built-in autoguider ports and have user programmable backlash compensation that adds even more precision to the tracking process.
In fact, the EQ6 has been described as “The best value in all of astronomy - bar none”. It has earned this reputation due to it’s enormous payload capacity, it’s high precision performance, and it’s amazingly affordable price. Its nearest competition costs more than double the price, yet has no better tracking performance and a lighter payload capacity.
If you need further convincing as to the capability of these mounts then just enjoy the accompanying astrophotos, all taken with the EQ6 or HEQ5 SynScan mounts. Using these mounts and readily available software, multiple images are done in seconds each with state-of-the-art CCD cameras. And then the images are processed allowing incredible photos which were unheard of just a few years ago, even with large observatory telescopes.
