TS-Optics Bahtinov Mask for Astrophotography - D= 65 mm to 100 mm Reviews

Wrote by Jarmo A E M. on 08.01.2026

"Mask works as assumed. However, it was said to fit also D = 65 - 100 mm wide telescopes. Mine has 98 mm outside diameter and it does not fit. Even without those plastic caps, which are great by the way. Of cource, if you attach it incorrectly screws inside the telescope front opening then it will fit, but that is not how it is supposed to be used. It is not secure way to attach it to telescope. Also the mask does not use the fully an apperture of a larger telescope. Diameter of grating area is small (about 57 mm) when compared for 90+ mm telescope apperture."

"Produkt funktioniert wie beschrieben. Ein Schwachpunkt in meinem Workflow war immer die Scharfstellung / Fokussierung bei der Astrophotographie. Problem erfolgreich gelöst."

"Eingesetzt für 70 mm f/6 Teleskop funktioniert es gut. Mit Objektiv 105 mm habe ich den Fokus nicht finden können."
