My Mewlon 250CRS is my main scope. Whilst it may be light, it still does require a decent mount. I use the Vixen AXD.
I use it for DS such as galaxies, globular clusters, and planetary nebula. For nebula, it's got kinda of a long focal lengh at 2500mm so NGC 6888 Crescent Nebula would fit in.
Being an F10 scope though somewhat longer exposures would be beneficial. I do use a cooled Sony A7S and have gone as long as 30 min subs (with a nebula filter).
