Ryan, didn’t Martin include those 3mm in the measurements he gave me? I applied exactly what he recommended and landed bang on 55mm.
One thing I have learned with astrophotography is that there are no “get out of jail free” cards. Any mistake will cost you when imaging! Hopefully coma will soon be a thing of the past for me. Also, not sure how the filter imperfections will affect imaging. They look perfectly clean, but when I shine them in the sun at the right angle, I see slight imperfections. Time will tell.
Thanks again,
