Problem with Vivitar (1607225) Telescope

eyepiece for telescope

Hello, I have a cheap Vivitar telescope. I was wondering if I could increase magnification from 100X to as much as possible by replacing 6mm eyepiece with another one for example 4 or 3 mm. OD of the scope's eyepiece is .965. I know that most eyepieces are 1.25OD. I can buy .965 to 1.25 converter, but I have a hard time finding innexpensive <4mm eyepeace. Could you help me locate such an eyepiece?
Thank you in advance,
Tony G.

However-- it is very doubtful if your scope can exceed 100 power without the image degrading. I normally use 100-150 power MAXIMUM in my 8" LX90 ---usually I use 50-100 power.

    • Hate to break it to you but that little telescope will never reach 500x--- under perfect sky conditions and perfect OPTICS the rule is no more than 50 times aperture-- your aperture is about 3 inches-- or less-- so 150x is the maximum possible magnification under PERFECT sky and PERFECT scope conditions--

      Once you exceed the maximum optics the image just gets BIGGER and FUZZIER AND DIMMER! --
