There is another resource here in IIS that does a similar thing. Have a look in the sticky thread:
DSO & Solar System sketches
These are sketches presented by fellow IIS members using scopes from small apertures to large, and from dark sites and light polluted skies. Galaxies, nebulae, open and globular clusters, planets, comets too. You will also get reports going with the sketches where you will also read the prevailing atmospheric conditions which have a great impact on how we get to see things. This is critical to understand as atmospheric conditions will dictate usable magnification regardless of how large your scope is, and how much detail can be pulled out.
