The air pressure of the atmosphere varies, depending on if you are at sea level or on a mountain. Unfortunately also the sensitive Etalon filter systems respond to these air pressure variations. The wavelength range that is allowed through the filters, shifts as a function of the air pressure. This shifting is indeed minimal, but at bandwidths of less than one Angstrom it is already clearly visible. If the filter is not adjusted precisely to the H-alpha wavelength, the image of the sun through the telescope degrades, prominences and surface details are no longer visible. Therefore, the \u003ca href=\"http:\/\/khanscope.com\/newEquipList.cfm?catID=1\u0026amp;subCatID=1\u0026amp;manID=40\" target=\"blank\"\u003eLunt Solar Telescope\u003c\/a\u003e Etalon filter systems have to be adjusted to the prevailing air pressure at the observation location. This Tuning called adjustment is typically done by a mechanical tilting of the filter. At sizes of a few Angstrom, it is obviously not easy to achieve the exact adjustment by mechanical tilting. And because the \u003ca href=\"http:\/\/khanscope.com\/newEquipList.cfm?catID=1\u0026amp;subCatID=1\u0026amp;manID=40\" target=\"blank\"\u003eLunt Solar Telescope\u003c\/a\u003e filter is no longer perfectly straight in the beam path, but slightly oblique, there may also be optical failures.\u003c\/p\u003e\n\u003cp\u003eThe new air-pressure system \"Pressure Tuner\" by Lunt Solar Systems takes a different path. The Etalon filter, part of the \u003cb\u003eLunt 152mm H-Alpha Solar Telescope\u003c\/b\u003e, will not be tilted to only simulate a balance to the air pressure, but the air pressure in the filter system is in fact adapted by 100 percent to the real external air pressure. Thereafter the air surrounding the \u003ca href=\"http:\/\/khanscope.com\/newEquipList.cfm?catID=1\u0026amp;subCatID=1\u0026amp;manID=40\" target=\"blank\"\u003eLunt Solar Telescope\u003c\/a\u003e Etalon can simply be compressed or decompressed by the tuning system in order to change the air pressure between the surfaces. This allows the Etalon surfaces to always remain at the same perfect angle to the light waves but changes the diffractive index of the air in the chamber and thus accomplishes the same tuning expect that it goes around + or - 0.4 Angstrom on either side of the centerline.

While it has minimal effect on prominences due to their location at the edge of the disk, it does have an effect on filaments and active regions on the surface facing us, not at the edge.\u003c\/p\u003e\n\u003cp\u003eWhile looking at a filament at the center of the Sun, the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of these desired Ha image features than is possible with a tilting etalon filter system.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLunt Solar Systems Internal Double Stack Module\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned to install in an existing LS152THa Solar Telescope\u003c\/li\u003e\n\u003cli\u003eAdds Double Stacking capability\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 7 pounds\u003c\/li\u003e\n\u003cli\u003eDimensions: 16\" x 16\" x 12\"\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eSingle Stack Bandpass: 0.45Å (telescope internal etalon)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eModule Etalon Bandpass: 0.35Å — individually verified\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDS Combined Bandpass: \u0026lt;0.28Å — LFPT (0.35Å) + MT internal PT (0.45Å)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTuning: Independent Doppler True Barometric pressure tuning\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eInstallation: Customer-installed — no factory return required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lunt Solar Systems","offers":[{"title":"Default Title","offer_id":31737851609201,"sku":"LUN-DSII\/LS152TP","price":4193.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/Double_Stack_LS130_LS152.webp?v=1778528703"},{"product_id":"lunt-solar-backing-plate-and-focuser-for-ls80mt-bp-f-ls80mt","title":"Lunt Solar Backing Plate and Focuser For LS80MT - BP\u0026F\/LS80MT","description":"\u003ch3 style=\"text-align: center;\"\u003eLunt Solar Backing Plate and Focuser For LS80MT\u003c\/h3\u003e\n\u003cp\u003eIf you have a Lunt LS80MT Modular Telescope and want to use it for nighttime, you can do it with this back plate and focuser assembly.

Now, they have \"raised the bar\" in the technology available to all astronomy enthusiasts, both for solar astronomers and for those typically doing nighttime astronomy. Features best-in-class resolution. In fact, now it is possible for astronomy enthusiasts to have the best of both worlds.\u003c\/p\u003e\n\u003cp\u003eLunt Solar Systems has produced their line of Modular Telescope equipment and they offer these telescopes in several aperture sizes. These instruments incorporate a design which allows you to easily convert one of their Modular Telescopes for either solar observation and imaging or nighttime, stellar-based observation and\/or imaging work. One of these products lets you explore daytime (solar) as well as nighttime skies!\u003c\/p\u003e\n\u003cp\u003eThe Modular Telescope line of instruments from Lunt Solar Systems provides the high level of optical image performance you expect from this manufacturer, plus a great design for mechanical integrity, ease of use, quick and simple modification to alter the telescopes's component complement for either solar astronomy or for exploring the wonders of our night sky. Lunt now offers the avid astronomer the ability to enjoy an All-In-One telescope design which will serve multiple purposes and still offer you the fully portable travel scope with the versatility you need for solar and dark-sky work.\u003c\/p\u003e\n\u003cp\u003eLunt produced this advanced line of Modular Telescope equipment by starting with an optical OTA with high quality doublet or triplet objectives which provide the basic lens and tube assembly needed, but designed the tube so the user can modify the back end of the instrument to suit their observing needs. For Ha solar observing or imaging, the user installs the Ha Etalon module and their chosen Blocking Filter along with an eyepiece on the rear of the tube. NOTE: It is critically important that the user installs a Blocking Filter with the Ha Etalon (as with a dedicated solar telescope) for safe operation. A Blocking Filter is integral to the safe operation of an H-alpha solar telescope. For nighttime astronomy, the user removes the pressure tuned Ha Etalon. Then depending upon which model telescope you have, the user either re-installs their focuser without the Blocking Filter or installs a backing plate with a focuser attached to use their equipment for nighttime astronomy.\u003c\/p\u003e\n\u003cp\u003eThen using a conventional star diagonal and eyepiece, the user focuses their instrument for a sharp stellar image. From there on, enjoy a good night of stellar and Messier observing! This All-In-One Ha and nighttime telescope from Lunt Solar Systems will be one of your best astronomical investments!\u003c\/p\u003e\n\u003cp\u003eThe Lunt Solar 60 mm Ha Modular Telescope is sure to delight, allowing viewers and researchers to delve into the fine details and surface phenomena of our ever changing Sun using its tried and true Doppler Tuning system. This telescope's 60 mm aperture is adequate for viewing many interesting details on our Sun. This model does not come with a Blocking Filter. A Blocking Filter will be required for safety. NO eyepiece is included.\u003c\/p\u003e\n\u003cp\u003eTrue Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user, adding a 3D-like component to the viewing experience.

Also included is a Lunt Red Dot Sun Finder\/Handle and a 8\" Vixen style dovetail and a case.\u003c\/p\u003e\n\u003cp\u003eTrue Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user, adding a 3D-like component to the viewing experience. While it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions on the surface. While looking at a filament at the center of the Sun the user can Doppler shift wavelength from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The Lunt pressure tuning system provides an order of magnitude more precision for the tuning of the desired features than tilt tuning will deliver.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel Number: LS100MT\/RP\u003c\/li\u003e\n\u003cli\u003eConstruction: Modular Refracting Solar Telescope\u003c\/li\u003e\n\u003cli\u003eStacking Type: Single Etalon\u003c\/li\u003e\n\u003cli\u003eSolar Telescope Aperture: 100 mm\u003c\/li\u003e\n\u003cli\u003eNighttime Telescope Aperture: 100 mm\u003c\/li\u003e\n\u003cli\u003eObjective: ED Triplet Lens\u003c\/li\u003e\n\u003cli\u003eSolar Filter Tuning Type: Pressure-Tuned\u003c\/li\u003e\n\u003cli\u003eH-Alpha or CaK Telescope Bandpass: Less than 0.65Å\u003c\/li\u003e\n\u003cli\u003eSolar Telescope Focal Length: 714 mm\u003c\/li\u003e\n\u003cli\u003eSolar Telescope Focal Ratio: f\/7\u003c\/li\u003e\n\u003cli\u003eBlocking Filter Included: None, (Filter is required)\u003c\/li\u003e\n\u003cli\u003eIncludes Lunt Red Dot Sun Finder\/Handle\u003c\/li\u003e\n\u003cli\u003eIncludes 8\" Vixen style dovetail\u003c\/li\u003e\n\u003cli\u003eEyepiece Included: None\u003c\/li\u003e\n\u003cli\u003eFocuser Included: 2\" Rack \u0026amp; Pinion\u003c\/li\u003e\n\u003cli\u003eIncludes: Mounting Rings\u003c\/li\u003e\n\u003cli\u003eAluminum finished hard case\u003c\/li\u003e\n\u003cli\u003eWeight: 12.5 pounds\u003c\/li\u003e\n\u003cli\u003eWarranty: Lunt 5 Years\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lunt Solar Systems","offers":[{"title":"Default Title","offer_id":40211005112433,"sku":"LUN-LS100MT\/R\u0026P","price":5873.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/LS100MT-Night-1_58932a77-a970-42a6-a437-4fb1a8dbbfd0.jpg?v=1776459110"},{"product_id":"lunt-solar-internal-double-stack-module-for-ls130mt-dsii-ls130mtp","title":"Lunt Solar Internal Double Stack Module for LS130MT - DSII\/LS130MTP","description":"\u003ch3 style=\"text-align: center;\"\u003eLunt Solar Internal Double Stack Module for LS130MT\u003c\/h3\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cstrong\u003e\u003cem\u003eNow with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment.
