Trying to get a workable solution out of this image was quite a challenge. I had not used my ASI6200 for about 8-10 months because I like to pair cameras with scopes and keep it on there. However I knew the Askar FRA400 could easily support full frame. My previous image with the Askar FRA400 was the propeller nebula, and I used the reducer for that. Unhappy with the stars produced by that combination, I decided I could match the field of view with the 6200 and get rid of the reducer. This did produce much better results, like way better. 

The first night I set it up for 30 HA and 30 OIII frames, and about 2/3 of the way through OIII dew formed on the sensor window. This really bummed me out and I lost a bunch of OIII frames to that. With another clear night ahead, I figured I would mess with the cooling settings to cool down the camera more slowly. After spending an hour on this, I had dew on every frame no matter the temp. I shined a flashlight down the barrel of the scope and noticed that the dew looked like "resi-dew" on the sensor, and sure enough it was. After the dew had dissipated it left a smudge right in the middle of the window. I decided rather than waste a night, I would take the whole assembly apart (since everything bolts together), clean the window and put it all back together again. I lost about two hours to this mess, then got the imaging going the same night.

The next morning I woke up and my imaging had stop short of the total number of frames I asked it to make. Turns out the guide camera disconnected part way through OIII. Well much to my dismay, after looking deeper into the problem, the ASI174MM-Mini guide camera is dead, and I can't get it to connect to any computer or the AIR. I've even tried other cables. As a fallback I have a second ASI174 that does work with all the cables and computers, so I'm positive its twin is dead. Really bummed by that, as these are not cheap guide cameras. I'm still within the two year warranty from ZWO, so I've contacted them to see if I can send it back to be fixed.

Anyhow, clouds rolled in, and my impatient side made me process the image as is and publish it. I'm done with the problems for now.
