Investigations into the Usage of Explore Scientific 82 degree Eyepieces
In the realm of amateur astronomy, the search for a wide field of view (FOV) eyepiece is a common pursuit. Enter the Explore Scientific 82° Ultra Wide Field eyepieces, a series that stands out from the crowd with its exceptional features.
For those who have been using Plossls, the difference is noticeable. While Plossls offer fairly sharp images for their price, their apparent field of view is only 52°. In contrast, the Explore Scientific 8.2o eyepieces offer an 82° apparent field of view, making them an ultra wide eyepiece. This ultra-wide FOV allows for a more immersive and panoramic sky view, enabling observers to see more of the night sky at once.
The superiority of the Explore Scientific eyepieces extends beyond their FOV. These eyepieces are noted for their high optical quality, incorporating advanced multi-element designs with premium glass and coatings. This leads to sharp, bright images with minimal chromatic aberration and edge distortions even at the wide edges of the field of view.
One of the key advantages of the 82° Ultra Wide Field eyepieces is their generous eye relief. With around 17-20 mm, these eyepieces are advantageous for eyeglass wearers and comfortable for long observing sessions. This is typically more than many other wide field eyepieces that may offer shorter eye relief.
The Explore Scientific 82° Ultra Wide Field series also boasts waterproof construction, purged with argon gas to prevent moisture from intruding and producing fogging or internal growth of mold and fungus. They also come with an eyecup, which helps position the eye properly on the eyepiece and block stray light.
In comparison to other wide field eyepieces on the market, the Explore Scientific 82° Ultra Wide Field series stands out by delivering a very wide viewing angle, superior optical clarity with advanced coatings and glass, and longer eye relief for comfort. These features combine to give amateur astronomers a premium visual experience that is both immersive and comfortable for extended use.
It's worth noting that the specifications of the 8.8 mm and 6.7 mm ES 8.2o eyepieces used by the author were not provided in the article. However, the 6.7 mm ES 8.2o produces a magnification of 179X with a true field of view of about 0.46 degrees.
Registering an ES 8.2o eyepiece within sixty days of purchase through Explore Scientific's website converts the one-year warranty into an Explore Star extended life warranty, a lifetime, transferable warranty that covers all accidents or damages.
The Explore Scientific 82o eyepiece is better corrected for use in lower focal ratio scopes, and does not show significant distortion or aberration when used with shorter focal ratio telescopes. It also performs well in high focal ratio scopes. The extended eye relief of the ES 8.2o eyepieces makes them more comfortable to use, especially for those who wear glasses.
In conclusion, for amateur astronomers seeking a premium visual experience with a wide field of view, the Explore Scientific 82° Ultra Wide Field series is a worthy investment. Its ultra-wide FOV, superior optical quality, and extended eye relief make it a standout choice in the market.
