Your First Solar Telescope: A Beginner’s Guide to Getting Started

You don’t need to spend thousands to see the Sun’s hidden face. Here’s how to choose your first hydrogen-alpha solar telescope.

You Can See Things on the Sun That Most People Never Know Exist

Most people have never looked at the Sun through a telescope. If you asked them what they would see, they would probably say "a bright yellow ball" and leave it at that.

They would be wrong.

Through a hydrogen-alpha solar telescope, the Sun transforms into something alive. Enormous loops of plasma arc into space from the Sun’s edge. Dark threads snake across the surface. Bright patches churn and evolve over hours. On a good day, you might witness a solar flare erupt in real time, or watch a prominence grow to a size that would dwarf the Earth.

All of this is happening right now, in broad daylight, above your head. You just need the right telescope to see it.

The good news is that getting started does not require a massive investment. Lunt Solar Systems makes two dedicated entry-level solar telescopes, the LS40THa and the LS50THa, that show you everything described above. Both come as complete, ready-to-observe packages. This guide explains what they do, what you will see, and how to decide which one is right for you.

What Is a Hydrogen-Alpha Solar Telescope?

A hydrogen-alpha telescope is a specialized instrument that filters out everything except one very specific color of light: the deep red glow emitted by hydrogen atoms in the Sun’s atmosphere. This light is invisible to the naked eye because it is overwhelmed by the Sun’s overall brightness. But when you block everything else and let only this wavelength through, the Sun’s atmosphere, called the chromosphere, becomes visible.

This is where all the action is. Prominences, filaments, flares, active regions, spicules. None of these are visible in white light. A regular telescope with a standard solar filter shows you sunspots and not much else. A hydrogen-alpha telescope shows you a completely different Sun.

Every Lunt hydrogen-alpha telescope is a complete, self-contained system with multiple built-in safety filters. You do not need to buy separate solar filters or worry about adapting nighttime equipment. The telescope is purpose-built for one thing: safe, detailed observation of the Sun in hydrogen-alpha light.

What Will You Actually See?

This is the question everyone asks, and it deserves an honest answer.

When you first look through the eyepiece, you will see a red-orange disk against a black background. Give your eyes 20 to 30 seconds to adapt. Then the details begin to emerge.

Prominences are the first thing most people notice. These are bright, flame-like structures extending from the edge of the Sun into space. Some are small and delicate. Others are enormous, stretching many times the diameter of the Earth. They can persist for hours or days, or erupt and vanish in minutes.

Filaments are dark, thread-like lines visible on the surface of the Sun. These are actually the same structures as prominences, but seen from above rather than from the side. They can stretch across a large portion of the Sun’s face.

Active regions are bright, churning areas where the Sun’s magnetic field is particularly intense. These are where solar flares originate. Watching an active region evolve over the course of a day is one of the most fascinating aspects of solar observing.

Surface texture is the fine, mottled pattern visible across the entire disk, sometimes described as an orange-peel texture. This becomes more pronounced as your eyes adapt and as you refine your focus.

On a particularly active day, you might also see a solar flare in progress, a sudden brilliant brightening in an active region, or even the beginning of a coronal mass ejection as a massive prominence erupts and expands into space. These events are rare but unforgettable.

Both the LS40 and LS50 show all of these features. The Sun does not hold back for smaller telescopes. For a more detailed guide to observing technique, read our Solar Observation Guide.

The LS40 and LS50: What’s the Difference?

Both telescopes show you the same solar features. The differences are in size, tuning method, and future upgrade potential. Here is a straightforward comparison.

	LS40THa	LS50THa
Aperture	40mm	50mm
Focal length	400mm (f/10)	350mm (f/7)
Tuning method	Tilt tuning	Pressure tuning (Doppler True)
What tuning means for you	Simple mechanical adjustment. Reliable and easy to learn.	Smoother, more precise adjustment. Enables Doppler scanning of solar features in 3D.
Bandpass	<0.7 angstroms	<0.7 angstroms
Prominences	Excellent	Excellent
Surface detail	Good	Slightly better due to larger aperture
Portability	Extremely compact and lightweight	Compact and lightweight
Double-stack upgrade	Available (front-mounted)	Available (LS50C screws onto front)
Best for	Maximum portability, first solar telescope on a budget, travel	Best balance of performance and portability, serious beginners, observers who want Doppler True tuning

 

If budget is the primary concern, the LS40THa Standard Kit gets you into hydrogen-alpha solar astronomy at the lowest possible price with no compromises on safety or core capability. You will see prominences, filaments, flares, and surface detail. It is a real solar telescope, not a toy.

If you can stretch the budget slightly, the LS50THa Standard Kit adds pressure tuning with Doppler True technology. This is a meaningful upgrade, not a gimmick. Pressure tuning gives you smoother, more precise wavelength control, altitude independence (it works the same at sea level or on a mountain), and the ability to Doppler-scan across solar features to see them in three dimensions. It is the feature that experienced solar observers consistently say they would not give up.

Standard, Enhanced, or Premium: Which Tier?

Both the LS40 and LS50 are available in three package tiers. Every tier is a complete, ready-to-observe system. The difference is in the accessories and capabilities included.

Standard

Everything you need and nothing you don’t. Telescope, blocking filter, eyepiece, case. This is the most direct path from purchase to first light. If you are not sure how deep you want to go into solar astronomy, start here. You can always add accessories later.

Enhanced

Adds upgraded accessories for a better out-of-box experience. Better focuser, sun finder for easy solar acquisition, and additional eyepiece options. The Enhanced tier is for someone who knows they want to commit to regular solar observing and wants to skip the "I wish I had gotten the better version" feeling.

Premium

Includes a double-stack filter that narrows the bandpass to below 0.5 angstroms. This dramatically improves surface contrast, making filaments, plage, and chromospheric texture much more visible. Many experienced observers consider double-stacking the single biggest upgrade in solar telescope performance. The Premium tier gives you this from day one.

Our honest advice: if this is your first solar telescope and you are not certain solar observing is for you, start with the Standard Kit. You will see everything the Sun has to show. If you fall in love with it, and most people do, you can upgrade to double-stack later. The modular design of every Lunt telescope means nothing is wasted when you move up.

What Comes in the Box?

Every Solar Ready Bundle is a complete system. Here is what you receive when you open the box:

The telescope. A purpose-built hydrogen-alpha solar telescope with internal etalon filter, energy rejection filter, and all required safety components pre-installed and factory-tested.

A blocking filter. This is the second critical filter in the optical path. It mounts at the eyepiece end and completes the filtration system. It is included and pre-matched to your telescope.

An eyepiece. A quality flat-field eyepiece that gives you a sharp, comfortable view of the full solar disk. You can observe immediately without buying any additional optics.

A protective case. Your telescope ships in and stores in a fitted case that protects it during transport and storage.

Enhanced and Premium tiers add: Upgraded focuser for finer focus control, sun finder for easy solar acquisition, additional eyepiece options, and (Premium only) a double-stack filter for maximum surface contrast.

Do I Need Anything Else?

Almost everything you need is in the box. The one thing you will need to supply is a tripod or mount to hold the telescope steady while you observe. Other than that, the Solar Ready Bundle includes everything required.

A tripod or mount (required). The LS40 mounts on any standard camera tripod with a 1/4"-20 screw thread — the same tripod you might already own for a camera. The LS50 includes a clamshell mounting bracket with a Vixen-style dovetail that fits any small astronomy mount, or can be adapted to a photo tripod. If you do not own a tripod at all, a basic photo tripod adequate for solar observing costs well under $50.

As you get more experienced, you might also want to add:

A sturdier mount. For longer observing sessions, a small astronomy alt-azimuth mount provides smoother tracking as the Sun moves across the sky. This is a comfort upgrade, not a requirement.

Additional eyepieces. Different focal lengths let you zoom in on specific features or zoom out for a wider view. The included eyepiece is a great starting point, and you can explore other options as you learn what you enjoy observing.

A double-stack filter. If you started with a Standard or Enhanced kit and want more surface contrast, adding a double-stack filter later is the single most impactful upgrade you can make.

Beyond a tripod, none of these are required to get started. The telescope, filters, eyepiece, and case are all in the box. Add a tripod and you are observing.

Is It Safe?

Yes. Every Lunt solar telescope incorporates multiple independent safety filtering stages. The system was reviewed and approved by a senior ophthalmology professor. Several individual filters in the system independently meet the safety threshold for solar observation. The full system exceeds it by orders of magnitude.

You cannot accidentally observe without the safety filters in place because the filters are permanently built into the telescope. There are no removable parts that could expose your eye to unfiltered sunlight. A person standing in normal sunlight receives more ambient UV and IR radiation to their eyes than someone looking through a Lunt solar telescope.

The 2026 Eclipse Is Coming

The total solar eclipse on August 12, 2026 will cross Europe, and partial phases will be visible across the entire continent, North Africa, and beyond. If you have been thinking about getting a solar telescope, the eclipse is a compelling reason to do it now rather than later.

A hydrogen-alpha telescope shows you far more than eclipse glasses do. During the partial phases, which last for hours before and after totality, your telescope reveals the same prominences, filaments, and active regions you observe on any other day, but with the added drama of watching the Moon slowly cross the solar disk. It transforms a brief spectacle into an hours-long experience.

More importantly, buying now means you have months to practice and develop your observing technique before the eclipse. Solar observation is a skill. The more time you spend at the eyepiece, the more you see. An observer who has been watching the Sun regularly for months will see dramatically more during the eclipse than someone using a telescope for the first time that day.

Get Started

The Sun is active, the eclipse is approaching, and there has never been a more affordable time to start solar astronomy. Pick the telescope that matches your goals:

On the tightest budget: LS40THa Standard Kit — The most affordable complete hydrogen-alpha system available.

Best value for serious beginners: LS50THa Standard Kit — Adds pressure tuning with Doppler True for smoother, more precise control.

Ready to go all in: LS50THa Premium Kit — Double-stack from day one for maximum surface contrast.
