Have for sale 150mm F10 optical tube with Istar h-alpha optimized objective. Great stuff for solar work with Quarks or solar mods using Lunt or Coronado etalons. I used it with Lunt LS100DS II (it has GSO flange diameter) and Coronado SM60 II internal etalon.
I can give advice with modification
Link to the objective:
Tube is made of carbon fibre and painted white. The output flange has 78mm diameter (standard GSO focusers).
Rings and Losmandy bar included. Inside the tube is an adapter for 105mm ERF (not included)
Tube has some marks of use but it's in good working condition.
Feel free to ask any questions.
Payment by Bank transfer or Revolut. I am located in Poland.
VENDORS WELCOME! Please, only solar equipment.
