Can't see any detail on planets with my new Celestron NexStar 130 SLT Computerized Telescope Mars looks like a small white blob/circle and the same with all other planets. This is very frustrating. I've looked all over for a solution jumping from site to site and nothing. Please be different on this site.

Edit: Many people have marked this post as duplicate. Yes, I know, but the other post did not answer my question.
Mars is a small planet and currently far from Earth (just over 1 Astronomical Unit). Therefore, it currently appears to be very small -- smaller than 9 arcseconds. At that size, it will look like a small disk. 

Based on this one observation, I think that no conclusion can be made about any possible problem.

Also, a 130 mm f/5 scope is rather short for planetary observing where you want high magnification. This scope is better for wide fields of view, such as the Pleiades or Double Cluster.
