Product description

More about the series HDC...

Extreme wide-angle eyepiece with best possible correction field geometry and colour errors.

The massive eyepiece body has a high-quality anodised finish, the lens system is fully multi-coated for high light transmission and the lens edges are effectively blackened.

Other special features:

  • Simple conversion from 2” to 1.25” by removing the threaded sleeve (excluding the 20mm eyepiece)
  • Waterproof version
  • Filter thread for 1.25” and 2” (excluding the 20mm eyepiece)
  • Conical upper eyepiece end for use on binocular attachments
  • Removable eye cups with M44.5 x 0.75 external thread for cameras underneath

The eyepiece is a perfect companion for Deep Sky observations even at high magnifications: the object remains fully visible, even if you want to observe a larger nebula or star cluster.

Space Walk Experience

Review by H. G. on 12.04.2020 07:47:30

( 5 / 5 )

For writing this review I used a Skywatcher ED80 Pro Series Apochromatic refractor along several eyepieces including APM HDC 13mm 100 Degrees Nitrogen Purged, Baader Hyperion 21mm, Meade Super Plossl 40mm and Explore Scientific Maxvision 24mm 82 Degrees.
The space walk experience with the APM was a shock after using a narrower field of view eyepiece like Baader Hyperion 21mm which has a 68 degree field of view.
I was observing at about 3 AM in the morning.. It was a relatively clear night, but cold. Therefore I kept the window closed and used the refractor indoors, looking through the double glazed windows. I observed a while with eyepieces with field of views of 40 to 82 degrees. Then I changed to this 100 degrees eyepiece. It was like a shock. Suddenly as if I was in the the middle of space, floating, looking towards these dazzling grouping of bright stars(they were actually magnitude 4 and fainter stars). These fusion cores of nucleusynthesis were in front of me. Quietly shining with dazzling blue light. I never before experienced such a thing when looking through an eyepiece. A true "space walk" experience. It's cold outside, there is no kind of atmosphere, I am all alone, more or less.
