Doesnt look like blooming to me, more like optical?


The sound of the fan fighting a breeze changes the sound note, I think this is more like a musical instrument effect than a failed fan..

Taken with 2 tube. First one is SkyWatcher 80ED, second one is TMB Optical 130.

Found the same problem...blooming with 2x2 RGB attempts. Look here:

Seems like if you want to do LRGB images they all have to be 1x1.

As i said in your post, it's not an issue for RGB.
