100mm H-Alpha Filter - w/ B3400 Blocking Filter in Extension Tube for 2" Focusers
- Lunt Solar Systems LS100 Hydrogen-Alpha Filter is an internally tuned Etalon system
- Provides incredibly high contrast views of solar surface and edge details.
- Lunt Solar Systems LS100 Hydrogen-Alpha Filter provides a bandpass of <0.7 Angstroms.
- 2" B3400 blocking filter included for refractors less than 3060mm focal length.
The new Lunt Solar Systems LS100 Hydrogen-Alpha Filter incorporates a unique design feature which decreases chances of decontaction (breakage) and increases solar filter thermal stability, an important factor since even the slightest temperature change can cause poor h-alpha performance. Since solar prominences tend to fade into the bright background sky at 1.0 angstroms, the Lunt Systems Solar Filter's performance at <0.7 angstroms gives above average contrast and definition. To help achieve greater details than ever before, the Lunt Solar Systems H-Alpha filter can also be enhanced by adding a second etalon system to reduce the bandpass of the LS100 H-Alpha to <0.5 angstroms. That's a substantial crisp detail bonus to both photographers and observers! The tighter the bandwidth, the more contrast and details on both prominences and surface features.
Another addition to the Lunt Solar Systems LS100 Hydrogen-Alpha Filter is the supplied B3400 blocking filter. This allows the Lunt H-alpha filter to be attached to any refractor with less than 3060mm of focal length. The Lunt Solar Systems B3400 Blocking Filter houses an additional filter in an Extension Tube for 2" focusers and includes a 1.25" eyepiece adapter. The blocking filter is just as crucial to your safety and the system's performance as the front element of the Lunt LS100 solar package! The secondary blocking filter is based on the focal length of your telescope - because blocking filters shape the spectral output. The Lunt Solar System's 34mm filter will provide a full disk image of the Sun with telescopes which have a maximum of 3060mm of focal length. It is important to chose your Lunt h-alpha solar filter carefully because using a larger blocking filter than necessary to achieve a full disk image in your telescope system may result in image "ghosts" at the edge of the field of view. Because the Lunt 100mm H-Alpha Front Mount Filter is unique, the H-alpha Blocking Filter is also unique and they must be used together otherwise safety and performance will be compromised.
Lunt offers high quality Adapter Plates for attaching Lunt front mount Etalon solar filters to most common brands of refractor telescopes. Contact Woodland Hills Telescopes (888-427-8766) for specific details and availability.
Lunt will only warranty the safety and/or performance of their solar systems when a Lunt Solar Systems blocking filter is paired with a Lunt Solar Systems Etalon system.

Introducing the LS100 Hydrogen-alpha system..... Although Lunt is in the final stages of patenting the large filter design. Lunt Solar does have pricing and projected delivery times. The LS75, LS100, and LS160 all have a unique design feature which allows for a more stable filter that is also less prone to de-contacting. (more information as is becomes available).
System includes the B600 standard for use on telescopes up to 600mm focal length. *Blocking filter required. Because the LS100 has an estimated bandpass of <0.75 Angstroms it is capable to providing high contrast views of both surface and edge detail. Adding an additional etalon system will reduce the bandpass to ~<0.55 (dependant upon scope) allowing for higher resolution viewing and/or imaging. This filter can also be added to the LS100T/Ha Telescope. Specifications: • Aperture: 100mm • Focal Length: Customer Supplied Scope • Band Pass: <0.75 Angstroms RMS • Color: Pearl White with Black Anodize System Includes: • LS100 Ha Filter. • B600 Blocking Filter (Other sized available by request) • Re-enforced case with foam.
