  1. :

    Can I use this lens for ASI224MC? I wanna make all sky camera.

  2. (verified owner):

    I’d got one for a ASI178MM-Cool and can’t reach focus. I used the T2 To CS or C adapter adapter
    I appears to say it should work with the ASI178MM what am I missing

      this lens is CS lens, cannot be used on our cooled camera whose back focus distance is 17.5mm

  3. :
