HELLO! I am the proud owner of the f15, 2250mm focal length, "Perseus" refractor telescope. I have it on top of a LOSMANDY G-11, which sits upon an Astro Physics Pier . I have 2 inch Ethos eyepieces with a 2" Takahashi diagonal.
But my stock focuser is a problem....gets loose...please suggest one. |

But my stock focuser is a problem....gets loose...please suggest one. The rear plate on your iStar scope should have M150 x 1.5mm metric thread size. MoonLite is producing their 2.5” large format focuser with iStar thread. All you need to do is to tell Ron of MoonLite to produce one with iStar thread size. Focuser will then fit directly without any reduction ring in between. I have one brand new focuser in stock in red color. I can offer it to you with 10% discount. Simply write directly to my email ales@istar-optical.com |

Hello, please contact Ron at MoonLite and tell him that you need a new large format 2.5" focuser with ISTAR thread size M100 x 1.5mm. He will produce a new focuser for you that will fit directly into your scope's rear plate. This would be the easiest and fastest fix. Let us know once you have your new focuser installed. |
