What kind of astrophotography is this ED80 and iEXOS-100-2 package best for?
This package is optimized for wide-field deep-sky astrophotography of large nebulae, galaxies, and star clusters. The combination of the 80mm apochromatic optics and the 0.8x focal reducer creates a fast imaging system ideal for capturing faint, expansive targets. The iEXOS-100-2 mount provides the accurate tracking necessary for crisp, long-exposure images.
How do I control the iEXOS-100-2 mount?
The iEXOS-100-2 mount can be controlled wirelessly using its built-in WiFi or Bluetooth. You can use the free ExploreStars application on a Windows, Android, or Apple tablet (sold separately). Alternatively, you can connect it to a PC and use the ASCOM driver to control it with popular astronomy software like N.I.N.A., Sequence Generator Pro, or Stellarium.
What do I need to add to this ED80 package to start imaging?
This is a very complete package, but you will need to provide a few items:
-
A Camera: A DSLR with a T-ring or a dedicated astronomy camera.
-
Power Source: The mount requires 8 'C' batteries (not included) or an external 12V DC power supply.
-
Finder Scope: While a finder base is installed, a finder scope itself is not included and is recommended for initial alignment.
Can the ED80 with the 0.8x reducer frame the entire North American Nebula (NGC 7000)?
Yes, this is an excellent system for very large targets like the North American Nebula (NGC 7000). The 0.8x focal reducer creates a wide field of view specifically designed to fit large celestial objects into the frame of a camera with an APS-C or smaller sensor, allowing you to capture the full expanse of such nebulae in a single shot.
Is the iEXOS-100-2 mount sufficient for imaging Jupiter with the ED80?
Absolutely. While the package is optimized for wide-field imaging, the iEXOS-100-2's precise equatorial tracking is also ideal for planetary work. For imaging Jupiter, you would typically remove the focal reducer and use a Barlow lens (not included) to increase magnification. The mount will keep the planet centered on your camera's small sensor for the high-frame-rate video capture used in planetary imaging.
Why is an apochromatic triplet like the ED80 better than a standard doublet refractor?
An apochromatic (APO) triplet uses a third lens element, including one made from extra-low dispersion (ED) glass, to correct for chromatic aberration. Standard doublet refractors can struggle to bring all colors of light to the same focal point, resulting in a purple fringe around bright stars. The ED80's triplet design ensures all wavelengths focus together, yielding sharper images with true-to-life color and higher contrast.
