Does light pollution affect astrophotography? Is it possible to photograph galaxies, nebulae or star clusters with our telescope also from the backyard with light pollution but using narrowband filters? Discover the result of our test comparing the image of a nebula recorded with the same telescope and the same exposition time but from a place with low light pollution and from an area near the city center.
Is it possible to have a single telescope to observe and take pictures of any object in the Universe, easy to use, power and transport? Is it possible to have a telescope that has the power of a small astronomical observatory but with the portability of an amateur telescope? After more than 20 years of experience in sky observation and astrophotography, we decided to launch a challenge, first of all to ourselves. And we want to share with you this challenge, showing you which telescope, mount, camera and accessories we chose, how to use it to observe and take pictures of any object in the sky, from planets and the Moon in high resolution to deep-sky objects like galaxies, nebulae and star clusters!
How to update EAGLE CORE with iOS 11: starting from version 11 (released in September 2017), the iOS operative system by Apple has added the File application that now allows us to upgrade the EAGLE CORE firmware even from iPhone or iPad. We periodically update the EAGLE CORE by adding new features and new cameras supported and, if you have verified that your EAGLE CORE does not have the latest firmware available on our website (click here to download), you can follow this procedure to update it. Open your File application on your iPhone or iPad, then select iCloud Drive. Continue reading
Celestron EdgeHD telescopes are the evolution of classic Schmidt-Cassegrains: not only they can be used in visual (unlike the SC, they are perfect also with very large apparent field of view eyepieces) and for planetary and lunar photography but, thanks to dedicated focal reducers, they are great instruments for long-exposure astrophotography. In this article we will see how to use them for this application and what are the advantages compared to other optical schemes often used by amateur astronomers like the classic Schmidt-Cassegrains or Ritchey-Chretiens.
Telescope mount, what to choose: “Power is nothing without control”, as stated by an advertisement, applies to telescopes as well, especially in astrophotography when taking long-exposure pictures of objects that are too faint to be seen. In fact, in order to take picture of celestial objects by using telescopes, it is essential to have an automatic tracking system to capture stars apparent motion: the mount. A mount is made up of a mounting head which is where the telescope is placed and allows it to move and rotate (and often electronically driven motors) and a tripod which holds up and stabilizes the telescope (thanks to three adjustable-height legs).
PLUS is the system of dovetail bars and rings for telescopes designed by PrimaLuceLab in order to connect in a modular way telescopes and accessories in a stable manner and without flexures. All elements are made of high-strength aluminum, sandblasted, with high thickness red anodizing treatment. All PLUS elements are designed to be connected to each other always with at least two screws (M6) to ensure the greatest possible strength and the total absence of flexions, very important for astrophotography.
People asks us what what are the softwares for Eagle that can be used in astronomy and astrophotography . The simple answer is pretty much everything! Eagle in fact also incorporates a computer with Windows operating system and then lets the user install and use the software they prefer. You can use sky chart softwares, autoguiding softwares, complete astronomical suites for instruments control or software for astrophotography automation: in this way you can customize your telescope.
One of the higher ambitions of many amateur astronomers is to have a backyard observatory. Who has available a sky with not too high light pollution in fact would like to have his telescope already installed and ready to use, without the need to assemble all the components each time to observe or photograph the sky. Having a fixed instrument also means that it's no longer necessary to perform the mount alignments (North Star and and star alignments) each time being then immediately operational.
Autoguide flexures: the use of an autoguider to improve the tracking accuracy of the telescope mount not only requires a sensitive camera and a good guide telescope (or an off-axis guider) but also a properly machined mechanical system that is able of supporting it without problems or flexures.
