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

 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!

Lunt Solar Systems Sonnenteleskop 50/350 LS50THa/B400PT

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!
