What is Reddit's opinion of Walmeck- Astronomical Telescope Eyepiece Broadband Green Film Eyepiece 1.25INCH 58 Degree Planetary Eye Lens 2.5MM / 3.2MM / 4MM / 5MM?

From 3.5 billion Reddit comments

Planets,

• 4mm 58°

  • [Aliexpress, reviewed] 1 2
  • Aliexpress cheapest
  • eBay
  • Amazon Marketplace
  • Amazon US/Prime
  • A ~$15 barlow would also get you more magnification, but introduce chromatic aberration = lowering the contrast.

 

If you want to check out some other eyepieces (not required, 4mm-10mm-20mm would get you the basics):

 

• Larger overview,

  • Field of view <em>simulation</em>
  • Aliexpress
  • eBay China (choose 32mm)
  • eBay US?
  • Amazon

• For in-between the kit eyepieces, a 15mm can be nice to have. Up to you. A 15mm Plössl is OK, a 15mm "gold-line" has longer eye-relief. Gold-line eBay, Plössl eBay / Plössl Aliexpress

• For smaller DSO & in-between the kit 10mm and the 4mm Planetary, a 6mm 66° ("gold-line" sold under various names) can be nice. Aliexpress, [Amazon] 1 2, [eBay] 1 2 US?
