I started with a setup like that but my scope was an 5" newt F/5 not an SCT so much easier to image with. If you want to seriously go down the imaging path the first thing to do is get a proper mount.

Definitely not for planetary imaging. You'll fit about one quarter of the moon disc in your fov at prime focus with the 178 and nearly all of it with the 183.

Sounds a little on the cheap side for a reducer. Got a link?

The 183 is 16mm diagonal which is still good for your scope corrected imaging circle. The 178 is only 9mm diagonal. Seems to be a very small sensor. Maybe the 183 is easier to use. Either way it will require some skill to land anything on a sensor that small with that mount.

You'll definitely fit the full moon on the Olympus without a reducer. You can shop for adaptors on eBay. There are stacks of them.
