  • Lunt SunLock Solar Alignment Finder

    The Lunt SunLock Solar Alignment Finder replaces dangerous guesswork with a precise red dot targeting system, allowing you to center the sun in seconds. Its versatile mounting slot accommodates both 1/4-20 and M6 screws with standard 1 inch (25.4mm) hole spacing for wide compatibility. A robust 3-point internal set screw system ensures that once your alignment is set, it remains locked through transport and use.

    The 3-Point System for Safe, Instant Solar Alignment

    Centering the sun without a dedicated finder involves projecting shadows or, worse, risking a direct glance. The SunLock eliminates this hazard by projecting a bright, safe alignment dot onto a glass reticle plane. Simply move your telescope until the dot is centered on the reticle, and the sun will be perfectly framed in your eyepiece, ready for observing.

    Universal Mounting with 25.4mm Spacing and Locked Collimation

    Built from red anodized aluminum, the SunLock is designed to stay aligned trip after trip. The 3-point internal set screw system is adjusted once and then holds its collimation, unlike external knobs that can be bumped during transport. The base features a slot compatible with both 1/4-20 and M6 screws at a standard 25.4mm hole spacing, enabling direct mounting to Lunt solar telescopes and many third-party systems.

    • Direct Lunt Compatibility: Mounts directly to Lunt LS40, LS50T, LS60, LS80THa, and LS100THa solar telescopes.
    • Adapter for Ring Mounts: For larger models or telescopes using tube rings, the ADPSOL adapter (sold separately) is required for mounting.
    • Durable Construction: The red anodized aluminum finish is rugged and perfectly matches the aesthetic of Lunt Solar Systems telescopes.

  • How does the Lunt SunLock work?

    The Lunt SunLock uses a small aperture to project an image of the sun onto an internal glass reticle. To align your telescope, you simply adjust the scope's position until the projected sun dot is centered on the reticle. This provides a safe, fast, and intuitive way to find the sun without looking through the main optics or risking eye injury.

    Will the Lunt SunLock fit my Lunt LS60THa telescope?

    Yes, the Lunt SunLock is designed for direct mounting on Lunt solar telescopes like the LS60THa, as well as the LS40, LS50T, LS80THa, and LS100THa models. It uses the existing mounting points on the telescope's clamshell.

    What do I need to mount the Lunt SunLock on a telescope with tube rings?

    For telescopes that use a ring-style mounting system instead of a clamshell, you will need the Lunt ADPSOL adapter plate (sold separately). This adapter provides the correct interface to attach the SunLock to the top of a tube ring.

    How does the 3-point internal alignment system on the SunLock improve observing?

    The alignment is controlled by internal set screws, not external knobs. This "set-it-and-forget-it" design means that once the SunLock is co-aligned with your telescope, it holds that alignment securely. You can pack up and transport your scope without worrying about the finder getting knocked out of collimation, saving you setup time at your next session.

    Can I use the Lunt SunLock with a non-Lunt solar telescope?

    Yes, the SunLock is highly versatile. Its mounting base features a slot that accepts both 1/4-20 and M6 screws and is designed for a standard 1 inch / 25.4mm hole spacing. This makes it compatible with Tele Vue slots and many other mounting systems from various manufacturers.

    What is the advantage of the Lunt SunLock over projecting the telescope's shadow?

    Projecting a shadow is an imprecise method that can be difficult to judge, especially with complex telescope shapes. The SunLock provides a distinct, bright dot on a clear reticle, which is faster and far more accurate. This ensures the sun is perfectly centered in your eyepiece every time, letting you spend less time hunting and more time observing.
