I replaced the standard focuser on my
Orion ED80 refractor with a
Moonlite Dual Speed CF Focuser. I am able to get much better clarity especially when imaging. As a newbie, I have been experimenting with post processing (i.e. Deep Sky Stacker, Registax, and Photoshop) to better my images. The results of some of this is below.
Addendum (2018)
Reprocessing some images to even out the background for a Messier Poster!
M3 - Globular Cluster with about 500,000 stars and 33,000 light-years from Earth located in the constellation of Canes Venatici. The bright orange star Arcturus located in Bootes can be used to locate this cluster which very difficult to view with the naked eye.

The following shots of the moon were probably the most focused shots I ever took. Even when magnified, they are still clear.
