Are 2 inch eyepieces worth it?
The reason to design an eyepiece with a 2 inch barrel is because the design requires a field stop that is larger that a 1.25 inch barrel will allow. Larger field stops provide wider fields of view. By the way, the field stop is the ring you see as the edge of the field of view.
What is the difference between the 1.25 and the 2 eyepiece?
A 2″ eyepiece will have a larger field stop than a 1.25″ giving you a wider field of view. Typically this would be for eyepieces 30 – 40mm focal length. Usually you only need one eyepiece in this range for your lowest power views.
What size telescope eyepiece do I need?
The largest-focal-length eyepiece you can use with your telescope is easy to calculate: multiply the focal ratio (the focal length of your scope divided by its aperture) by 7. For example, your Newtonian scope is f/5: the largest-focal-length eyepiece you should use is 35 mm.
Do all eyepieces fit all telescopes?
Unlike microscopes, eyepieces for telescopes are interchangeable. However, not all eyepieces will work equally well for all telescopes, the shorter focal ratio telescopes are very hard on simpler and less well corrected eyepieces.
What are the different types of telescope eyepieces?
What are the different types of eyepiece?
- Plössl eyepiece. Plössls have a wide field of view (around 52°), so they can be used successfully for planetary as well as deep-sky viewing.
- Radian eyepiece. The Radian is one of the newer types of eyepiece on the market.
- Nagler eyepiece.
- Orthoscopic eyepiece.
- Barlow lens.
Which telescope lens is stronger 10mm or 20mm?
The larger one is normally between 20mm and 25mm and is the lower power (lowest magnification). The smaller (higher magnification) is normally around 10mm. A larger image to start with will allow the eyepiece to produce a larger image to view (higher magnification).
What is the best focal length for telescope?
A good all round first telescope should have a focal length of around 1000mm to 1200mm. All refracting telescopes use a glass lens as their primary focusing unit.
