Not really...for the moon and planets it'd be fine. For DSO's, f12 will give you closer views of small area targets, like most PN's and such, but for large nebs and galaxies you'd have to use a focal reducer, get it down to at least f6. Only problem being with the small aperture, that long FL will cut back on the brightness of the images quite a bit. Alright for the big and bright objects (moon and planets) but not so great for anything else.
