Need help on ghosting. Hi, I am new on 130PDS and I found that when I use this scope with SW coma corrector to do high contrast DSO imaging such as M42, I will get some ghosting. (I use APS-C DSLR) Here is an example with β Orionis. Is it possible to fix it through flocking or some other things without changing my corrector? If not, is Baader MPCC III a good choice? Because I heard that this one cannot correct the coma as good as the SW one PS. I modified the mirror clip to make cleaner diffraction spike and I use L-pro filter. But the ghosting has been there before I modified or imaging without filter
