    I wouldn't worry about grit on the mirror. It would be affecting all of your targets and not just Saturn. It seems that everyone is complaining about Saturn lately and I can add no helpful insight to what has been already offered. I have a 8" reflector and I still haven't been able to tease out the Cassini division either but we can still keep trying.

    I plugged your telescope specifics into my little handy dandy calculator and it says that 54X (9mm) should produce your best seeing.

    What scope or you using? the Meade 114 EQ?

    The Zhumell 8-24 zoom EP was mentioned as a option to buying several EPs. I have it an am very happy with it. Most nights it is the only EP that I use. You can get it here Telescope Eyepiece Accessories - Shop at Telescopes.com for $55.00.

    Good luck and clear skies

    This is an Image I captured of Saturn Saturday night 5/14/2011.

    This is with Celestron 8SE and Celestron NexImage.

    But I am not sure what the magnification works out to???

    When conditions are less than perfect (in other words always) and I'm stubbornly pushing the scope to higher than optimal magnification (in other words always) then I find that patience will usually yield some positive results. You will have to keep looking for a while, maybe several minutes but if conditions are not excessively poor there will be moments of clarity when the image will suddenly become crisp for a second or two. Resist the temptation to be constantly fidgeting with the focus, set it as best you can and then wait.

    I have a 12" and I couldn't see the division at first but I eventually got a pretty good look at it.

    Something you might check that could cause your "streak of light" is the diagonal. Make sure it don't have a booger or something on it. Something on your diagonal could cause this streak. It would be more likely to show up on a bright object like Saturn than it would other stars ect.

    Just something you can check thats easy.

    I can more often than not see the Cassini division from my back yard (often seeing is better in the city), but I typically use 300X magnification or more with my 12 inch Dob when looking at planets or the Moon.

    I have to respectfully disagree with folks who say you can see better planetary detail at lower magnification. This is why: given a well-focused image, it is easier to see larger things than smaller things. This is why they make large print books. I agree that at some point more magnification makes the image so blurry you can't see the detail, but to see the most detail possible you want to magnify as much as you can, right up to the point just below where the image no longer goes through moments of clarity.

    Like Steve (Procreator) and others have said, it helps to be patient and wait for moments of clarity when the image becomes clear for a second or two.

    my telescope has a focal length of 1000mm. a 9mm eyepiece makes a magnification of 111x or something can i see it at 54x? infact i think its the size. i guess i should upgrade from a 4.5 to 16"

    You are correct, It would have helped if I looked in the correct cell. An 18.5mmEP will provide 54X. I apologize for the confusion. (reminder to self.. double check your figures)

    Seeing has been attrocious here in NW PA for over a month now. We had record rainfall in April, and unsettled skies on the few clear nights. Last clear night was May 9. It was a perfect example of excellent transparency, but poor seeing. Picked up some rather faint galaxies; NGC 3389 for one. However, just seeing the gap between Saturn's rings and the planet's surface was a challenge. Even the moon looked like it was at the bottom of a pot of simmering water at times. Frustrating, but the calmer days of summer are on the way. (along with the skeeters)
