Robert you have two reflectors which should be good for planets and DSO's. If you are keen for a refractor 5" to 6", f5 to f8 then you can think of it as low power wide field instrument. If you use it at lower magnifications around 6x to 10x per inch of aperture then you will find it gives wonderful images. These refractors are not really best at lunar and planets.
I have a 6" f5 Jaegers and a 6" f15 D&G. The Jaegers will show heaps of violet colour if used for lunar or planets at magnifications over 60x. However it is an amazing wide field scope at magnifications of 25x to 45x and is a lot of fun at a dark sky site. It is made for comet sweeping and cruising the milky way. The D&G starts at 60x (40mm eyepiece) and is good up to 200x for all kinds of objects. It does show some minimal false colour but the detail and contrast are so good that the false colour is easily forgotten.
There is a wonderful book called Starlight Nights by Leslie Peltier. Mr Peltier grew up on a farm in the USA and had use of a 6" f8 refractor. He used it for all kinds of visual astronomy but was most famous for observing and recording variable stars over many years.
I suggest you try a refractor, I think you will enjoy it so long as you have reasonable expectations.
