Product information "LUNT LS40FHa H-alpha double-stack filter for LS40THa"
Double-stack filter for LS40THa telescopes.

The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.

Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing.

FEATURES
  • Aperture: 40 mm
  • Bandwidth: <0.55 Angstrom
  • Tuning: mechanical tilt-tuning
  • Housing diameter: 70mm
  • Length: 60mm
  • Weight: 0,3kg
  • only usable together with a LS40THa telescope!

LUNT LS40THa/B500 H-alpha solar telescope
Solar observation in H-Alpha: prominences, filaments, flares ... the most spectacular way to see the Sun - easy and affordable with the LS40THa.Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B500 blocking-filter, and Helical focuser.The LS40THa/B500 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (no central obstruction) and 400mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An Etalon with mechanical tilt-tuning provides <0.7 Angstrom bandwidth.Fine adjustment is achieved with a 1.25 inch Helical focuser. Blocking-filter is the B500, this is good for visual observation of the sun. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepiece connection.The easy handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it is also a good travel telescope for the experienced solar observers.The LS40THa telescopes are available with choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes have only a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera item number 4959050.FEATURESAperture: 40mm (no central obstruction, 2-lens refractor)Focal length: 400mmBandwidth: <0.7 AngstromTuning: mechanical tilt-tuningBlocking filter: B500 with 1.25 inch connectionFocuser: Helical focuserDovetail bar at standard GP-level1/4-20 tapped base (standard thread for photo-tripods)Sol-Searcher includedWeight: 1.2kgLength: 41cmSCOPE OF DELIVERYLS40THa Solar TelescopeB500 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual

BRESSER ICD 30.5mm Widefield Eyepiece 15x
The 10x eyepiece is suitable for all microscopes with 23.2mm eyepiece tube diameter. This diameter is widely used in stereo microscopes, also from other brands or manufacturers. Please select the eyepiece magnification in correspondence to the objective you are using. A low objective magnification allows for a higher magnification of the eyepiece. For example, combined with 4x or 10x objectives, eyepieces with 20x or 25x magnification can be used without loss of image quality. With a 100x objective, a 10x or 12.5x eyepiece is usually the highest recommended eyepiece magnification. To calculate the maximum useful magnification, consider the numerical aperture (N. A.) of the objective lens: numerical aperture of the objective lens x 1000 = max. useful magnification Here is a typical example: for a 10x objective with numerical aperture NA 0.25, a maximum of 250x magnification can be realized. This is realized with a 25x eyepiece. The numerical aperture is usually printed besides the magnification factor on many objectives. Magnifications beyond the max. useful magnification do not show any further details (so-called “empty magnification”) and are therefore not recommended.

EXPLORE SCIENTIFIC MPCC Field Flatt. ED APO+Canon EOS T2
The image plane of many telescopes is not plane, but curved. This results in a picture that has its optimal focus only in the center of the field of view - the edge of the field is out of focus and thus unsharp. The human eye is able to accomodate most of this but a camera will show stars that get increasingly unsharp towards the edge of the field. The Explore Scientific Multi Purpose Curvature Corrector eliminates field curvature in a variety of telescopes - Explore Scientific Apos and many other refractors and cassegrain telescopes. This increases the edge sharpness in the image drastically. Improves edge sharpness not only with Explore Scientific Apos, but also with many other refractor and cassegrain telescopes. This image field leveller fits all Canon EOS cameras, but can also be used for other camera types due to the universal T2 thread connection.
