Though it’s marketed as a white-light photo voltaic telescope, the iOptron 80mm White Gentle Photo voltaic Scope is mostly a nighttime scope (which will be bought by itself) alongside a removable photo voltaic filter from Thousand Oaks. This can be a perk for customers who do not personal a telescope and wish to buy a equipment that is prepared for each photo voltaic and lunar viewing. Nonetheless, it is probably not of curiosity to anybody who already has a bigger scope.
The telescope is light-weight with a streamlined design, and two helpful eyepieces are included. The smaller aperture of the telescope — 2.4-inches (60mm) with the photo voltaic filter hooked up and three.1-inches (80mm) with out the photo voltaic filter — makes this telescope extra appropriate for learners. And, the worth is affordable for this viewers.

iOptron 80mm White Gentle Photo voltaic Scope: Design
- Easy aluminum physique in brilliant blue
- Modern 60mm photo voltaic filter
- Conventional 9mm and 25mm eyepieces
The iOptron 80mm telescope is a simple-looking refracting telescope with a 3.1-inch (80mm) aperture. It is brilliant blue, with a transparent iOptron brand on the finish of the telescope. On the base of the telescope, there’s a rack-and-pinion focus with a 1.25-inch (32mm) eyepiece slot. The shortage of a finder scope and the eyepiece opening on the very finish of the scope give it a modern and streamlined look. The equipment additionally features a 45-degree erect glass prism, permitting for simpler viewing of high-altitude objects. Easy 0.35-inch (9mm) and 1-inch (25mm) eyepieces are additionally included.
A novel promoting level of this telescope is the featured SolarLite photo voltaic filter from Thousand Oaks. The filter has a easy design, mounting onto the tip of the telescope with three screws. The photo voltaic filter has an aperture of solely 2.4 inches (60mm), which decreases the usable aperture measurement from the three.1-inch (80mm) telescope measurement. Thousand Oaks is a reliable producer of photo voltaic filters, so you possibly can have peace of thoughts that the filter is secure.

The iOptron 80mm was designed primarily as a night-sky telescope, which is obvious from the security label with a warning in opposition to its use for photo voltaic observations. This label is considerably useful, to remind you to connect the photo voltaic filter earlier than pointing on the solar. Nonetheless, it could be complicated for patrons who bought the telescope-solar-filter bundle particularly for photo voltaic viewing. Relaxation assured: With the photo voltaic filter hooked up, photo voltaic viewing is secure.
The beauty finishes on the telescope will not be high-quality. The plastic rack-and-pinion focus has small, white discs to cover the screws beneath, but one popped out throughout my first observing session.
iOptron 80mm White Gentle Photo voltaic Scope: Efficiency
- Simply seen sunspots
- Inclusion of helpful 9mm and 25mm eyepieces
- Views of soppy, golden-orange solar
- Doubtlessly problematic plastic focus knob
I examined the iOptron 80mm White Gentle Photo voltaic Scope on a transparent, cloudless day at round 4 p.m. The solar was not at its highest by this time — however I stay in a dry location over 5,000 toes (1,500 meters) above sea degree, so atmospheric situations are typically fairly secure for nighttime and photo voltaic astronomy.
With the photo voltaic filter hooked up, the aperture of the telescope is just 60 mm huge. By way of the 9mm eyepiece, the solar crammed up the view properly, however the wider 25mm view was extra forgiving for non-tracking mounts. The solar appeared a pleasant golden orange via the photo voltaic filter.
The telescope carried out as anticipated for a 60mm aperture white-light scope. Sunspot areas have been seen (even via the 25mm eyepiece), with the distinction between the umbra (the darkish middle of the sunspot) and the penumbra (the lighter fringe of the sunspot) on the fringe of visibility to a eager eye. As with all photo voltaic observations, your viewing expertise will rely on the scale and presence (or lack thereof) of sunspots on a given commentary day, which is able to change consistently. On the time of my observations, solely small sunspots have been close to the middle of the solar, with a bigger area rotating into view.
The pictures above present a comparability between {a photograph} taken via the iOptron telescope (a single shot from a Sony A7 IV with a Barlow lens) and a white-light picture of the solar from the space-based Photo voltaic Dynamics Observatory. Naturally, the picture from area is way clearer and sharper, however the iOptron telescope nonetheless picked out the entire sunspot areas. A extra formidable photographer may get hold of sharper solar photos by stacking a number of photos collectively.
My major criticism with the telescope’s efficiency is the plastic focusing knob, which is somewhat stiff and never of the best high quality. After I turned the knob, it prompted the telescope to wobble a good quantity and thus required readjustment of the telescope.
iOptron 80mm White Gentle Photo voltaic Scope: Performance
- Light-weight, transportable design

The 45-degree erect glass prism is a pleasant inclusion; it means that you can angle the eyepiece away from the telescope for simpler viewing whereas the solar is excessive within the sky.
The iOptron 80mm White Gentle Photo voltaic Scope has a primary design. It lacks a finder scope, which would wish its personal photo voltaic filter, or at the very least a sign of the place the solar is relative to the pointing. Against this, most devoted photo voltaic telescopes embrace this function that will help you discover the solar. Because of this, it might take newbie astronomers somewhat time to seek out the solar inside the subject of view.

Nonetheless, there are opinions of the telescope with out the photo voltaic filter, rated on its use for nighttime astronomy. On the Excessive Level Scientific web site, two opinions independently point out the problems with the main target knob that I additionally discovered throughout my testing:
“A great primary refractor telescope. Helpful for terrestrial daytime viewing and huge subject viewing of moon, and huge objects like comets. Nonetheless, low-cost plastic focusing housing causes picture shift making astrophotography troublesome. (4/5)”
“The view via the iOptron 80 is nice, however there’s a downside with focusing. Once you flip the knob to focus, the article strikes backward and forward relying upon which manner the knob is turned. Typically it may transfer utterly out of view. You may see the eyepiece holder transfer facet to facet as you flip the knob backwards and forwards. (3/5)”

If you wish to put money into a solar-specific telescope, then H-alpha observations present a much better view of the solar than white-light photo voltaic telescopes do. White-light filters are restricted to observing the solar’s floor, the photosphere, whereas H-alpha filters observe the next layer within the solar’s ambiance, known as the chromosphere. As well as, H-alpha observations can reveal filaments known as photo voltaic prominences. Nonetheless, H-alpha telescopes are way more costly than the iOptron 80mm White Gentle Photo voltaic Scope. Trusted H-alpha manufacturers embrace Lunt, which sells 40mm, 50mm and 152mm-aperture choices.
