Absolutely! Primary mirror coma is a tiny aberration (increasing in a linear fashion from centre to edge) and only a high quality eyepiece will show it in its purest form. In fact the first time I saw pure coma I thought it was quite beautiful. I only use a Paracorr when I try and get my Newtonian views to look similar to my TV-101 but most of the time coma does not bother me even at f4.5.
