    I would never discourage anyone from at least having a try , providing you have the correct filters...but I suspect the angular diameter of the object is too small to be seen with the set up you describe.
    
    Having said that.....give it a go .... if nothing else it will be good practice for a transit of ISS , which on a good transit has an angular diameter of over 40" !
