There's a continuum of OK, better, and best.
You can image with an SCT on an alt-az mount. You take a very large number of very short exposures, to minimize field rotation.
You can put the mount on a wedge. Now you can take longer subs. But, that inexpensive mount was never designed for astrophotography. And, in particular, the various bits; the fork arms, the bearings, were not designed to work at that angle. They will flex, and that will impact image quality. On a 14 inch, that will be a serious issue (focal length magnifies tracking errors, a lot). You'd not be getting the best the scope has to offer.
Or you can place the OTA on a good (and necessarily expensive) German Equatorial mount. Since the designed is aimed at managing the loads well, it will do the best job, make the best images. The solution favored by experienced imagers.
You can choose where you want to be on that continuum, it's a personal choice. But don't fool yourself. A fork mount that was designed as an alt az mount will not do as good a job as a GEM. The mount is the most important part of a DSO AP setup. People don't put SCTs on GEMs because they like the look. They do it to make better images.
