Starlight Instruments 2.5" Adapter for Coronado Solar Max 90/Solar Max II
This Starlight Instruments adapter provides the specific mechanical interface required to mount a 2.5" Feather Touch focuser onto your Coronado Solar Max 90 or Solar Max II telescope, enabling the precise, zero-image-shift focusing needed to resolve fine solar prominences and delicate surface granulation.
A Rock-Solid Foundation for Your 2.5" Feather Touch Focuser
Your Coronado Solar Max is a premium instrument, and it deserves a focuser to match. This adapter creates a perfect, non-flexing mechanical union between the telescope body and a Starlight Instruments 2.5" Feather Touch focuser. The precision machining ensures perfect optical alignment, so you can take full advantage of the focuser's capabilities without introducing tilt or slop into your optical train.
Precision Focusing for Prominences and Surface Detail
The key to breathtaking solar views is critical focus. By allowing you to upgrade to a dual-speed Feather Touch, this adapter transforms your observing and imaging sessions. You gain the ability to make minute, repeatable adjustments, snapping low-contrast details like spicules and plage into sharp relief. For imagers, the elimination of image shift and the robust support for a camera are non-negotiable advantages over the stock equipment.

Which Starlight Instruments focuser does this adapter fit?
This adapter is specifically designed to mount any Starlight Instruments 2.5" Feather Touch focuser to the body of a Coronado Solar Max 90 or Solar Max II telescope.
Will this adapter work with a Coronado Solar Max 60 telescope?
No, this adapter is engineered exclusively for the Coronado Solar Max 90 and Solar Max II models. It will not fit the Solar Max 60 or other Coronado telescopes due to differences in the mechanical interface on the telescope body.
Why should I upgrade the focuser on my Coronado Solar Max 90?
Upgrading to a Starlight Instruments Feather Touch focuser provides significant advantages for solar observation. Key benefits include:
-
Dual-Speed Control: The 10:1 fine focus knob allows for extremely precise adjustments, which are critical for resolving fine surface detail and prominences.
-
Zero Image Shift: The stock focuser can cause the image to move when changing focus direction. A Feather Touch eliminates this, which is essential for high-magnification viewing and imaging.
-
Higher Load Capacity: A Feather Touch can securely hold heavier cameras and accessories without flexing or slipping.
Is the installation of this Coronado Solar Max 90 adapter difficult?
Installation is straightforward for users comfortable with basic telescope hardware. It typically involves unthreading the stock focuser assembly from the rear of the telescope and threading this adapter in its place. The 2.5" Feather Touch focuser then attaches to the adapter. Always follow the specific instructions provided with your focuser.
Does this adapter allow the Feather Touch focuser to rotate?
The rotation capability is a feature of the focuser itself, not the adapter. Most Starlight Instruments focusers are rotatable, allowing you to orient your eyepiece or camera to the most comfortable angle. This adapter provides a solid, non-rotating base for the focuser to attach to.
Can I use this adapter to attach my imaging camera directly to the Solar Max 90?
No, this is not a camera adapter. Its sole purpose is to connect a 2.5" Feather Touch focuser to the telescope. Your imaging camera would then be attached to the focuser using standard 2" nosepieces or other threaded adapters.
