I did things a little backwards earlier. I'm going to submit 4 straight out of camera images. I'm seeing various issues, It's not really blur. To me it looks like light issues. Exposure needs to be longer/shorter, light leak. I didn't replace the eyepiece. The lens could have hot spots. I had the same issues yesterday though. This could be the reason people do the conversion instead of the filter. The exposure time isn't an issue it's the other things. Most of the said issues can be managed during post processing.
