Lunt LS152THa Solar Telescope

The Lunt LS152THa is currently the largest solar telescope available, and is sure to provide the most stunning balance of resolution and performance.

The 100% unobstructed system will perform to the highest level at both low and high magnifications. Utilizing both advanced high-contrast coatings, and the new Doppler True Pressure Tuning system, the user will be able to experience crisp, sharp, high magnification visual images, as well as utilize this system for high end digital processes.

True Doppler Tuning

True Doppler Tuning allows for a shift into and away from the user. Adding a 3D like component to the viewing experience. While it has minimal effect on proms due to their location at the edge of the disk, it does have an effect on filaments and active regions on the surface.

While looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.

This system has an optional, interchangeable, CaK module allowing for the research of multiple wave lengths thru the same platform. You can also convert the LS152THa for nighttime viewing with a special backing plate & focuser kit.

The Lunt Solar Systems LS152THa Solar Telescope is perfect for the Intermediate to Advanced User.

    This is one of the best imaging scopes I’ve used in the past 15 years for h-alpha close up images. The tri-band adaptability of the design makes it configurable to what ever view you are in the mood for. It delivers enough resolve and detail to show you the most tiny features on the Sun and gives you that “Wow” feeling every time you look through it. Its a pretty stout scope that requires a heavy duty mount but if you’re looking into a first class trip to the Sun this is definitely the only way to fly. The close up images this scope delivers are second to none, rich with action and packed with high resolution.

    My buddy, and I love our new Lunt LS152 solar-scope. It is an incredible scope with amazing optics…First light was amazing. The views were spectacular. It was nice to have my own 152 so I could zoom in on the limb and see the spicules with my own eyes. It was incredible, the details and brightness of the disk. With the camera I could easily view this with the Lunt 60 but with my bare eyes, I cannot resolve this fine detail. I shared the views with my neighbors, friends and will be bringing the scope to 4 day Astrophotography workshop I am instructing in two weeks at the Adirondack Public Observatory. (I blocked out a block during the day to each solar imaging and will be running the 152 as the imaging platform.) I also am an advisory board member at the Adirondack Public Observatory ( and I will be bringing this setup to many outreach events. In addition, I attend NEAF every year and will be getting in on the Solar Party action and share the views with the 152.

    I am an avid solar imager and post many images on my “Connolly Astronomy” Facebook page ( I always tag Lunt’s Facebook page in my posts when I use your equipment so look out for more exciting photos!

    I am definitely not a stranger to Lunt. I have the Lunt LS60, double stacked with a LS50, a Lunt Engineering 80mm, Lunt Engineering 102mm and a Lunt Ca-K B1200 module.

    I attached several images of first light and the first image I captured with the scope. I used the LS152 with a 2.5x powermate and an ASI174mm camera.

    You can see the huge smile on my face and I haven’t stopped smiling. I can’t wait to receive the double stack and Ca-k module for the 152!

    Thanks a lot!
