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