      Hello Umair: You may want to see if the Ted Agos focal reducer would be
      compatible with your setup. It works great with my 10" f/10 LX200 SCT/JMI
      Focuser, AO7, CFW8a/ST7e setup. This allows me to image at near f/6.3 with
      a very flat field and this is also a long imaging train. HTH's and CS. Bob
