That's a vast improvement, although there is some noise it is acceptable, generally you will beat down the noise with more exposures.

At 1.4 megapixels and a 10 inch rcx that would be a fairly small field of view, and you are showing quite reasonable tracking as stars are fairly round, you may find one or two that have lost a little, you could try using a median combine method on this image when you stack and see if it helps a little bit.... It may not.
What I suggest you do, is find the brightest deep sky object to hone your skills on, this will give you the satisfaction of seeing some clear detail and inspire you then to move on to harder things, you will have to forgive me for my lack of northern hemisphere knowledge.... Down here that would be Eta carinae or M42 , then you would move on to m8 . A wild stab would suspect it to be one of the Messier objects, I will have a look in a planetarium program tonight to see if I can find something suitable.
In the meantime have a try at the median combine method, the last image you put up shows promise and given time and experience you will be right up there. If you want to do faint objects it really is about time in exposures ( hours and hours).
you should have the confidence to know what you have can produce the goods.
