The Moon has a lot of great contrast, unfortunately this makes a single shutter speed and a single exposure non-optimal. You will want to take as many frames as you can...start with around 24, taking a couple of hundred is not unheard of...or crazy talk...more is better. For your shutter speed take some test images at various speeds until you have three speeds: under exposed, just about right and over exposed, think of it as an HDR subject in gray scale. Your going to mix these in post with the under exposed images will provide detail of bright ejecta and crater rims and the over exposed will provide detail for dark or shadowed areas. Add shutter speeds if you have black shadows or blown out ejecta. You might also consider taking some dark frames every 30 minutes or so...lens cap on, shutter speed at 2x the slowest you are using and click...subtracting these from your images will cancel any hot pixel defects (although at fast shutter speeds they may not be necessary).
Now the fun begins... pre-process, stack, post-process...Don't be surprised if you end up doing this more than once. It takes me around 18 hours to process a 24 image galaxy stack...nebulae can take significantly longer.
A bit of blur is hard to avoid, mostly it comes from shooting through the atmosphere and some nights are better than others. This is another advantage of having multiple exposures; you can toss out the worst offenders...like the one where you bumped the scope or caught a contrail. The cool part is that with the right software package and a process called deconvolution you can correct most atmospheric blurring and get a nice sharp image.
Processing astro images is a lot of work...but the finished product can be one of the most spectacular images you will ever see...worth the effort in spades.
Things your going to need/want for a start...
The Handbook of Astronomical Image
Processing. The Bible. Comes with a really great software package for processing images. Noise reduction, stacking, deconvolution, wavelet filters, color mapping, kitchen sink, etc. Excellent.
RegiStax Free image stacking software, very powerful, one of the very best for planetary images. User interface is a bit odd increasing the learning curve...but hey... did I mention it was free ?
PixInsight The Photoshop of astrophotography. Amazing feature set with excellent implementations of the high level functions: wavelet processing, star masks, deconvolution, etc. It is in a league of its own. The package price is very reasonable and the do have a trial.
The images you posted look like a great start...just be careful. If you don't want to get hooked on this hobby (read: obsession). I would advise you: Stop now.
