I don't know why people are not mentioning it.  With a large Dob that is an F-4.5 you need a coma corrector. GSO (in Taiwan) makes a very good 2" coma corrector. They make them for several different brands. I bought one for my 14" Dob.  AgenaAstro sells them. for $115.  I recently bought a 180mm Maksutov.  I'm going to do a side-by-side comparison viewing of the planets when we get some clear sky.

For the small planetary fields I don't think you need a coma corrector. 

A good Barlow would be better to allow longer fl eyepieces to be used.
