Removing dust motes- planetary imaging

[Andy R]

As the title says is there away of removing dust motes from doing planetary imaging ie AVI recordings during the stacking or any other time. I’ve got the 6se out tonight and set up the cam only to find the corrector plate mirror is covered in black specs😭from adding a red dot finder bracket to it a long time ago. 
I suppose the long term solution would be to do a bit of research and see about removing the corrector plate but er well that’s for another day and a scary thought. 
 

Any help or advise very much appreciated.

Any dust that is far away from focal plane - which really means filters or sensor cover window - won't leave any significant shadow for planetary purpose.

I advocate for doing flats for planetary as well - but most people don't bother. Planet often drifts enough during the recording so that any dust shadow due to particles on camera window will simply be swamped with other regular pixels.
