Considering the mount has not been aligned with the RH200 and thus polar alignment is not quite right and no guiding and no flats and rushed rough and ready processing with a paucity of data drawing any conclusions would be premature evaluation. Even focus was just by eye and not by any definitive objective method, Cloud interrupted anything more substantial.
Conversely considering the conditions this system is a real goer. It just needs some dedicated tweaking. I have not even started collimating and aligning the optical axis with the imaging train. It has all just been bolted together without any fine adjusting.
Here is the OC data cleaned up with GradientXterminator 15MB

And a quick NGC 6357 20 min HA. ie 10x2 min. Remember this is 3nm NB at F3 with NO flat correction!
