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 freshmen. And, the value is affordable for this viewers.

iOptron 80mm White Gentle Photo voltaic Scope: Design
- Easy aluminum physique in shiny 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 shiny 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 package 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 singular promoting level of this telescope is the featured SolarLite photo voltaic filter from Thousand Oaks. The filter has a easy design, mounting onto the top 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 may 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 protection label with a warning towards 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. Nevertheless, it could be complicated for purchasers 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 should not 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 sentimental, golden-orange solar
- Probably 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 ft (1,500 meters) above sea stage, so atmospheric situations are typically fairly steady for nighttime and photo voltaic astronomy.
With the photo voltaic filter hooked up, the aperture of the telescope is just 60 mm huge. Via 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 by the photo voltaic filter.
The telescope carried out as anticipated for a 60mm aperture white-light scope. Sunspot areas have been seen (even by 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 dimensions and presence (or lack thereof) of sunspots on a given remark day, which is able to change continuously. 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 by 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 far clearer and sharper, however the iOptron telescope nonetheless picked out all the sunspot areas. A extra bold photographer may receive sharper solar photographs by stacking a number of photographs collectively.
My main criticism with the telescope’s efficiency is the plastic focusing knob, which is a bit stiff and never of the best high quality. Once I turned the knob, it triggered 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 iOptron 80mm White Gentle Photo voltaic Scope has a fundamental design. It lacks a finder scope, which would want its personal photo voltaic filter, or no less than a sign of the place the solar is relative to the pointing. Against this, most devoted photo voltaic telescopes embody this function that will help you discover the solar. Because of this, it might take newbie astronomers a bit time to seek out the solar throughout the area of view.

“A great fundamental refractor telescope. Helpful for terrestrial daytime viewing and huge area viewing of moon, and enormous objects like comets. Nevertheless, low-cost plastic focusing housing causes picture shift making astrophotography tough. (4/5)”
“The view by the iOptron 80 is nice, however there’s a drawback with focusing. Whenever you flip the knob to focus, the item strikes backward and forward relying upon which means the knob is turned. Generally it may well transfer fully out of view. You possibly can see the eyepiece holder transfer facet to facet as you flip the knob backwards and forwards. (3/5)”

If you wish to spend money on 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. Nevertheless, H-alpha telescopes are rather more costly than the iOptron 80mm White Gentle Photo voltaic Scope. Trusted H-alpha manufacturers embody Lunt, which sells 40mm, 50mm and 152mm-aperture choices.
