hi again Raj, found this page on cloudy nights, which backs up Scott's suggestions.

you need to have all the factors come together to see the CD. I'm sure last year I saw the division through my 113mm reflector but conditions were perfect, and using my cheap 21mm barlowed. I havnt had the chance to see Saturn this year (only with binos) as the weather has been a pain in se qld.
hopefully that page will help, and most defiently take your scope to an astro night, people will be keen to help you out no doubt with your concerns about the scope etc.
good luck
matt
