help Explore Scientific 100mm APO FAQ
What can you see with an Explore Scientific 100mm APO refractor?
A 100 mm apochromatic refractor can show the Moon in sharp detail, split many double stars, and reveal bright planets such as Jupiter and Saturn. Under dark skies, it can also frame larger deep-sky objects like the Orion Nebula or the Pleiades.
Why choose a 100mm APO refractor for astrophotography?
The 100 mm aperture gives more light and resolution than a small 70 or 80 mm refractor while staying easier to mount than a 127 mm scope. An APO design helps reduce purple fringing around bright stars, which matters for long-exposure imaging.
Does an Explore Scientific 100mm APO need a field flattener?
For visual observing, usually no. For DSLR or dedicated astronomy-camera imaging, a field flattener or reducer-flattener is commonly used so stars stay sharper near the corners of the frame.
What mount should I use with a 100mm APO refractor?
For visual use, a sturdy alt-azimuth mount can work well. For astrophotography, an equatorial tracking mount from brands such as Sky-Watcher, iOptron, or Celestron is usually more important than the telescope tube itself.
