Customer Questions & Answers
-
Question:
Is it 2" or 1.25"?
Answer: The 16mm eyepiece is 1.25". -
Question:
How does this eyepiece compare to the TeleVue 24mm Panoptic?
Answer: The Explore Scientific eyepiece offers superb performance with even light transmission and tack sharp images. It also provides a great field of view and eyecup to block out external light. It is difficult to compare to the TeleVue without firsthand experience, but any differences are likely to be minimal. -
Question:
Do you test every eyepiece in a meter of water for 30 minutes?
Answer: Yes, each eyepiece is tested for at least 30 minutes in 1 meter of water. -
Question:
Do I need an adapter ring to use the 2" eyepiece with the 8" Orion Intelliscope?
Answer: The 8" Orion Intelliscope comes with a 2" crayford style focuser and a 1.25" adapter, so no additional adapter ring is needed. -
Question:
Does this eyepiece have threads to attach to a dslr?
Answer: No, it does not have threads to attach to a DSLR. Consider eyepieces from Baader Morpheus or Hyperion lines if this capability is important. -
Question:
Do any of the Explore Scientific 1.25" eyepieces have a thread for a T connector to a camera?
Answer: No, they do not have a thread for a T connector to a camera. -
Question:
What sizes come with this set? How many lenses?
Answer: The Explore Scientific set includes 3 eyepieces at 1.25" diameter (16mm, 20mm, 24mm) and 2 eyepieces at 2.00" diameter (30mm and another likely 35mm or 40mm). The eyepieces are not sold as a set and need to be purchased individually.
