First attempt at the moon.

This is my first attempt at shooting the moon with my new 55-250mm. How can I get a clearer image? Everything seems in focus when I zoom in in live view. But they are coming out a bit blurry. Any advise would be appreciated.

Just my 2c:
You might consider registax in which case you'll probably make a movie and stack the best images. There are tutorials on youtube.
The #1 thing in astrophotography is by far the mount. #2 is the telescope & optics and the sensor is usually third, but not by a long way.
A motorized equatorial (fork or GEM) will improve things a lot. A barn door tracker will also work. Good polar alignment are important for both. An equatorial type mount (as opposed to alt-az) is critical for long exposures.
Depending on the "seeing", you'll probably want to use the shortest exposure you can otherwise the atmospheric lensing will make things blurry. Your wet warm eyeball adapts to the seeing, but the camera sensor is not so forgiving.
I also use the clear dark sky website to find the best times and nearby locations to observe.
Try playing with the luminance curve to show more detail in the illuminated area.

its going to be tough to get a good shot of the moon with the 55-250. The exposure is not too far off. Try using the moon exposure rule f11 at the iso. for instance if using iso 800. then manually set the camera f11 @ 1/800 Then just bracket around those setting untill you are happy with the exposure.

Stacking shots can help as well. DSS "deep sky stacker" can be used. it's free. google for it you will find it.
It's my opinion that you should use a tripod. not everyone will agree.
I haven't tried moonshots with my 55-250 yet, only had a week or so. But i did with my 75-300 and got reasonably good shots. the 55-250 should be better.

With a little practice you should be able to get a better shot than the one above
