Lunt LS80THa/B1200CBT är ett kvalificerat solteleskop med 80 mm objektiv för solobservationer i H-Alfa våglängden. Etalon-justering genom "Pressure Tuning". Lunt LS80THa H-alfa solteleskop med B1200 blockfilter och pressure tuning Lunt Solar Systems i Tucson Arizona erbjuder dedikerade solteleskop i både H-Alpha och Calcium K våglängderna. Det mest effektiva sätt att observera Solen på är att använda sig av ett H-Alpha filter. Ett H-Alpha filter isolerar vätets våglängd (656,28 nm) och filtrerar därmed bort de övriga av ljusets våglängder. Detta möjliggör fantastiska observationer av Solen med dess solfläckar, protuberanser och mycket, mycket mer. Finjustering av Etalon-filtret görs med lufttryck, s. k. "Pressure Tuning", vilket ger en jämnare belysning av bilden än med en mekanisk justering. Finjustering av fokus görs med en Crayford fokuserare med en fin 1:10 utväxling. Denna Crayford fokuserare är riktigt kraftig så man kan utan problem hänga på sin DSLR (spegelreflexkamera). Lunt LS80THaB1200CPT kan kompletteras med ett dubbelstackningsfilter för förbättrad bandbredd till < 0,5 Å.
