I would suggest getting an f/5 scope instead.
The Morpheus eyepieces are marginal at f/4 without a coma corrector.
With a coma corrector, which typically increases the f/ratio 10-15%, you might be OK.
And an f/5 won't really inhibit your imaging.
Plus, the f/4 scope has a very large secondary, optimized for imaging, not visual.
Just be sure to get an adequate mount for the reflector. It will require a larger and more heavy duty mount than the 100mm refractor.
Even if the weight is similar, the "wind sail" factor means the mount has to be a real rock or needs to be in an observatory that shields the scope from wind.
