DSLRs are great astrophotography cameras (even for long exposures of deep-sky objects such as galaxies, nebulae or star clusters) since they have high sensitivity and low noise, so they are able to record very weak details. Just use an equatorial mount with autoguide port and EAGLE CORE will allow you to record wonderful images of the objects of the Universe both using photographic lenses and telescopes! Thanks to EAGLE CORE, your instrument will have the high performance of an astrophotography telescope but with the portability and ease of use of a star tracker.
Compared to EAGLE2, that thanks to Windows operating system and the ability to install any astrophotography software is perfect for the astrophotographer that wants to make advanced astrophotography, EAGLE CORE is designed for those who start to do astrophotography and are searching for a very simple to use system or for those who want an easily transportable system as "travel telescope".
In order to make high quality astrophotography, connecting a DSLR to the telescope is not enough. It is necessary to be able to set and shoot the camera without touching it to avoid vibrations while recording and use the autoguide to automatically correct normal tracking errors of equatorial mounts. When using an external computer, telescope becomes complicated because of many cables or power supplies, it is less portable and it is necessary to study the capture and guide software. EAGLE CORE simplifies both your telescope and software, making your instrument easier to use and transport.
Technical comment by Filippo: "Using EAGLE CORE is like having a capture software for your DSLR camera and an autoguide software, all in your smartphone or tablet! Personally I use it with Celestron SkyQ Link 2 or Simulation Curriculum SkyFi III to remotely control with WiFi also the mount: this way I can control telescope position from one app (like SkyPortal or SkySafari) to align and slew it to the object I want to record. Often I move to the mountains but I also photograph from my backyard controlling the telescope from the sofa!"
As for other EAGLE control units, EAGLE CORE is installed directly on your telescope, it powers the elements of your telescope (12V, up to 3 instruments) and it has a modular PLUS case allowing you to install it on all telescopes and to personalize your configuration as you prefer. It has also been designed to allow you to do long exposure astrophotography even with telephoto lenses thanks to a special shooting mode with the guide scope positioned at the telephoto lens side (see photo below).
In order to use EAGLE CORE together with a telephoto lens (and guide scope in parallel) you have to add "140mm PLUS dovetail bar" to be connected under EAGLE CORE body, in order to install everything on the equatorial mount. In the upper part the Eagle Core has a 1 1/4" photo thread to connect a photo ball head and then the camera. If you have an heavy photo lens (for example with focal length higher than 200mm) you can add the "PLUS Vixen+Losmandy dovetail clamp". Then you can connect the "PLUS 90mm Vixen dovetail bar" under the camera and then connect everything in the dovetail clamp. The guide scope is installed, using the optional 90mm PLUS guide rings, on the lateral side of Eagle Core.
In order to use EAGLE CORE with a telescope (and guide scope in parallel) you can connect it directly above the PLUS support rings of the telescope (below the PLUS support rings you need to use a PLUS Vixen or Losmandy 140mm dovetail bar). Above EAGLE CORE body you can connect PLUS guide rings with guide scope (where to insert the guide camera).
- Control DSLR and guide camera from your smartphone or tablet with a convenient WiFi connection: you will be able to see in real time pictures of guide stars or of the object recorded by your DSLR camera
- Remotely control your Canon EOS or Nikon DSLR camera: set acquisition parameters, then start capturing a single image or a sequence. These are the cameras already tested and verified with EAGLE CORE (we're testing other models, if your camera is still not in this list you can also ship to us and we'll send you EAGLE CORE tested with your camera):
- Canon EOS 1000D (Rebel XS/Kiss F), 550D (Rebel T2i/Kiss X4), 600D (Rebel T3i/Kiss X5), 700D (Rebel T5i/Kiss X7i), 20D, 40D, 60D/60Da, 6D, 5D Mark III
- Nikon D3300, D3400, D5600, D7000 (D7000 can't "B" mode), D600, D610, D750, D810
- Remotely control autoguide camera: thanks to the integrated autoguide software, it automatically corrects tracking errors of the telescope's mount (compatible with QHY5II-L and Lodestar)
- Use dithering: in order to minimize electronic noise and get a better image when you stack more pictures of the same object (* feature available soon, it will be added with a software update)
- Power up to 3 devices (12V): thanks to optional cables and adapters, you can power the DSLR camera, the mount, etc directly from the EAGLE CORE eliminating the need for other batteries and other external power supplies.
Thanks to EAGLE CORE you will no longer need a laptop: in fact it includes EAGLE OS software to control autoguide and DSLR camera. You can control all capture and guide parameters directly on the screen of your smartphone or your tablet (compatible with iOS and Android devices) connected to EAGLE CORE through the convenient WiFi connection.
Thanks to the innovative design protected by international patent application and Italian utility model, EAGLE CORE has 3 power OUT ports that you can connect (using the optional cables) to different devices such as camera or mount. In this way you will have only one power cable to power EAGLE CORE and other devices and you will reduce not only total consumption but also the number of cables in your instrument. You can also use the optional "Eagle-compatible power cable for Canon EOS and Nikon DSLR camera" to power them from EAGLE CORE (removing the battery you will no more have problems with batteries running out of charge during capturing!).
Using the autoguide feature of EAGLE CORE, classic tracking error of the equatorial mounts are corrected: in the image below you can see how a 300 seconds exposition picture recorded at 200mm focal length shows stars not well tracked if the autoguide is not activated (left) and perfectly tracked when we use the autoguide (right).
EAGLE CORE comes with an astrophotography introduction user manual (in english and italian) that not only shows how to use EAGLE CORE but also teach the basics of astrophotography like how to properly set the equatorial mount, what is the autoguide and how to set it properly, why stacking more pictures together, etc. For esample, here you have part of the user manual:
