Being very slow f no , is no big deal , will have very deep depth of field , and you can compensate with modern DSLRs by setting the camera ISO to a higher value to keep the exposures short.
Is it too slow for astroimaging .... no not really , it appears to have big front lens so light gathering will be pretty good , it'll probably be OK but will have quite restricted field of view.
I wonder if they have a telescope conversion, bung on an eyepiece and it's probably a decent refractor.
