Special Offer! The SUNocular 8×32 from Lunt

February 12 2019, Stefan Taube

Imagine a solar telescope that is just as manageable as a pair of binoculars, or a pair of binoculars that can be used to observe the sun as safely as if using a regular solar telescope. The SUNocular 8×32 from Lunt is precisely that. This unusual instrument for observing the sun is currently available at a special price of 98 euros. You will get 121 euros off the recommended retail price!

Lunt Solar Systems solar binoculars 8×32 SUNocular OD5

 

The SUNocular 8×32 features a permanently installed lens filter with a neutral density of 5, as is typical for sun filters designed for visual observation and allowing you to safely look at the sun. Since the filter is permanently installed, the SUNocular 8×32 is not suitable for use as binoculars for terrestrial observations. In order to ensure that there is no confusion on this point, we have classified this product under the Solar Telescope rubric for the sake of simplicity.

The SUNocular 8×32 allows you to see the photosphere of the sun. This layer, approximately 500 kilometres thick, creates almost all of the sun’s radiation in the visual spectral range. The photosphere shows sun spots with an eleven-year activity cycle.  We are currently between two cycles, and for this reason there are very few spots to be seen. But that will soon change, and this instrument allows you to be very well prepared when the change comes. You can observe, at any time and from any location, new sun spots appear as well as their day-to-day development.

The SUNocular 8×32 has all the typical features of a pair of binoculars of this size: central focus, dioptre balance, extremely rotatable eyepieces, carry strap and a very sturdy bag. Furthermore, the rubberised housing provides excellent grip!

By the way… The SUNocular 8×32 is also suitable for observing planets as they cross in front of the sun (transits) and for watching solar eclipses!

 

Special Offer: A Lunt H-alpha solar telescope at a special price!

November 30 2018, Stefan Taube

 The LS50THa / B400PT solar telescope from Lunt Solar Systems allows safe solar observation in H-alpha-light. This wavelength allows you to observe prominences, filaments and other exciting phenomena in the sun’s atmosphere. We are currently offering the LS50THa / B400PT for only 999 Euros! Saving you 326 Euros when compared to the previous price!

The somewhat cryptic designation LS50THa / B400PT describes the characteristic features of this solar telescope:

  • Its 50mm aperture and 350mm focal length make it particularly compact and allow it to be used on a camera tripod.
  • The H-alpha filter only passes light at a focal length of 656 nanometres, with a peak width at half-height of less than 0.75 angstroms.
  • B400 stands for the value of the cutting filter, which is located behind the H-alpha filter and reduces the intensity of sunlight. B400 means that it has a band pass of 4 millimeters.
  • PT stands for Pressure Tuning: The Fine-Tuning of the H-Alpha Etalon Filter is achieved via variation in air pressure. This ensures a particularly homogeneous image field.

The telescope is equipped with a helical focuser. But you can also purchase a matching and very high-quality Feather Touch focuser at a special price!

Another possible improvement is a reduction in the peak width at half height of the telescope. You can add a second H-alpha filter to the telescope. The matching LS50C module is also greatly reduced in price! This process, called ‘double stacking’ increases the contrast of the structures seen in H-alpha light.

But it is not only the LS50ThA / B400PT which is available at a reduced price, but also the special eyepieces for it, which are optimized for H-alpha light.

These eyepieces are available as a complete set or individually  – with a saving of 47 Euros per eyepiece! And of course you can also use these eyepieces on any other telescope with H-alpha filters.

The offer is valid until 31.12.2018 and only while stocks last. Grab yours now!
