What is the purpose of the Starlight Instruments 2.0" Adapter for Lunt Telescopes?
This adapter is a custom-machined part that allows you to remove the stock focuser on certain Lunt solar telescopes and replace it with a high-precision 2.0" Starlight Instruments Feather Touch focuser. It creates the necessary mechanical connection between the optical tube and the new focuser.
Which Lunt telescopes is this adapter compatible with?
This adapter is designed to work with four specific Lunt solar telescope models: the Lunt LS60, LS80, LS100, and LS152.
Which Feather Touch focusers does this Lunt adapter work with?
The adapter is designed for two specific 2.0" Feather Touch focuser models. The correct focuser depends on your telescope:
- Use with the FTF2015BCR focuser for the Lunt LS60 and LS100.
- Use with the FTF2025BCR focuser for the Lunt LS80 and LS152.
Why should I upgrade the stock focuser on my Lunt LS80 for solar imaging?
For solar imaging, maintaining a perfect, stable focus is critical. A Feather Touch focuser, enabled by this adapter, offers zero image shift and the rigidity to hold a heavier camera without flexure. Its fine-focus control allows for the minute adjustments needed to capture the sharpest possible surface details and prominences, which can be difficult with a standard single-speed focuser.
Will this adapter help me see more detail in my Lunt LS100?
While the adapter itself does not change the telescope's optics, it enables an upgrade to a focuser that allows you to achieve and hold a much more precise focus. This enhanced control makes it easier to resolve the finest details your Lunt LS100's optics are capable of delivering, especially during moments of steady atmospheric seeing.
Is installation of this Starlight Instruments Lunt adapter difficult?
Installation is generally straightforward for users comfortable with basic telescope hardware. The adapter is designed for a direct fit, typically involving unthreading the stock focuser from the optical tube's rear cell and threading this adapter in its place. The new Feather Touch focuser then attaches to this adapter.
