My philosophy is :"it will be much easier to find objects that are well within the reach of a big scope,as opposed to straining to see objects at the limit of a small scope".
For most objects in the NGC list in a 12", you should be able to spot them if they are in the field of view. From personal experience, if you can't find it, it's because you're looking at the wrong place.
How large does your relector have to be to....

The non-existent ones I've expunged from my viewing list.
I observe, typically, at high altitude, under NELM 6.8+ skies, and occasionally at sites with even darker skies. "Challenge" objects I try to observe only when on/near the meridian. There are some of magnitude 15-16 in my log.
I've had a little more trouble with some UGC, PGC, and MCG galaxies, with quite a few NF (Not Found) markings.
When a catalog lists the magnitude as fainter than 15, look at the size. I find that if it's under 1' in size, it's often a lot easier than the 2-3' size at magnitude 14.
Note that there is a difference between "detect" and "observe". Some of the NGC objects are quite faint. And some of the UGC, PGC, MCG and ESO galaxies are easy enough you wonder why they aren't in the NGC.
For a list of the brighter 23,000 galaxies, see the 3rd Reference Catalogue (RC3) of Vaucouleurs, list downloadable from the web. That'll keep you busy for a few weeks.

under dark sky conditions
I was careful to report that my observations were from my back yard and I live in Central Austin.
I encouraged the OP to seek dark skies if he wanted to be successful.
Sounds like we were in general agreement.

I have an implant lens in my left eye. I can see into the ultraviolet a bit with it. If there's a UV filter coating on it, it still allows some UV through. And it was done here, in the US.
