The svbony telescope eyepiece cap is suitable and reliable and fits well with your daily purpose. This is a pretty solidly-made collimator and adapter. It is built with metal material. The adaptor is used with telescopes that use the larger 2" eyepieces. The most unique feature of this is the variable brightness of the laser. It comes with any laser collimator you have to check to make sure the laser itself is properly aligned.
The SVBONY Laser Collimator comes nicely packaged in a box so that it safely makes it to your door, and also a good way to store it. This tool makes it easy and fast to collimate a Newtonian Telescope at home or in the field.
Why We Like This:
Worked perfectly, aligned mirrors in seconds
Good quality, works very well for aligning scopes
Shows perfect dot at lower brightness, even at 30 feet

The astromania telescope eyepiece cap's material feels more premium than its price would suggest. The reflector in the Cheshire needs bright light to assist in collimating, but the mirrors only require medium light. It can be used for precisely collimating the newtonian and schmidt-cassegrain reflector telescopes for better image quality. The eyepiece should be inserted to a depth such that the bottom edge of the eyepiece tube appears slightly wider than the outer edge of the secondary mirror when you look through the sight hole. It fits in 1.25" focusers and is easy to use.
The eyepiece is beautifully manufactured of heavy duty metal with an excellent finish. It is made by aluminum with crosshair at the bottom to allow quick and precise centering of the optics. They are glued into holes in a ring that threads into the end of the tube. It has a polished flat set in the barrel at a time.

The svbony crosshair eyepiece is capable of outshining several other cap featured in this list in overall features in its price range. This V152 20 mm premium 125" wide angle eyepiece includes an illuminated single crosshair reticle that greatly simplifies centering celestial objects in the eyepiece for more accurate go. The threaded extinction inside the eyepiece can well suppress the reflection of internal stray light. The Focal extenders are designed to have very snug fits, and depending on the make and model they can occasionally be too snug. It's basically as quick as any fancy plate solving and makes polar alignment fun, if you can believe that.
The optical quality of this eyepiece is pretty good. They are also bright enough to use in daylight at the upper end of the range. There are also other uses for the V152 crosshair eyepiece. The lighting part of the product is removable.
Why We Like This:
Internal matting thread to reduce stray light entering the eyepiece

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate cap. The astromania focuser tube is exactly that - it's a simple cap that hits all the right notes. It is the process by which an instrument’s optical components are brought into precise alignment with its optical axis and mechanical axis. It can be used as a common way of collimating—the “quick and dirty” method—is to simply remove the eyepiece and look down the focuser tube to center the mirror reflections. It is made of high-quality metal aluminum, with dustproof and moistproof rubber cover-expert design-cnc machine made. It contains detachable lens covers to protect the product from dust when not in use.
It is great for when using a 2" focuser, place the collimating eyepiece into a 1.25" adapter.
