Piggyback without the wobble. The 280CW tube rings let you mount a guide scope, camera, or other accessory parallel to your Mewlon-250 series OTA, so everything rides in perfect alignment with your main instrument instead of fighting it for space.
Purpose-built for the Mewlon-250 family. With a 280 mm internal diameter, these rings are sized specifically for the Takahashi Mewlon-250, Mewlon-250CR, and Mewlon-250CRS reflectors, so the fit is exact rather than "close enough."
A top plate that's ready to work. The included top plate arrives drilled and threaded for accessory mounting, giving you attachment points right out of the box instead of a bare ring you have to modify yourself.
Light enough to forget it's there. At just 3.2 kg for the set, the rings add minimal bulk to your rig, so you get the mounting flexibility without eating into your payload budget.
Plays well with your existing mount. The rings ship without a bottom plate or dovetail, so you're free to pair them with whatever plate or dovetail your mount already uses, as long as the hole pattern and centre distances line up.
Built for the Takahashi ecosystem, but not locked into it. Prefer to keep everything in the family? Pair the rings with Takahashi's own CW-plate (TKA84421) for a mount built to match, bolt for bolt.
Precision hardware from a name astrophotographers trust. Like everything else Takahashi builds, these rings are machined to hold their fit night after night, so your accessories stay put through slews, meridian flips, and long imaging sessions alike.
