I'm still fighitng IN Lunatic and got really close recently. (Hourai Jewel). I need more consistency before that though. So here are my problem areas.
Huh. I just re-cleared this with default lives, so I'll try to help.

Epheremality: There's no re-directing to be done (other than Keine's movement, she follows you), but try to shoot down minimum 2 familiars per wave.
3rd and 4th spells: captured in my replay. Go between the gaps and I guess read and dodge, although the pattern for her last one is static/aimed.
Just bomb Asteroid Belt. It's not worth going for in a 1cc run.
Tewi: Using Border Team, I found a consistent method to bomb her first part only once with no dodging, as seen in the replay.
Stage 6 opening: lower left corner is the easiest place to dodge from, again just bomb it.
Eirin's nonspell is stupid. 2 bombs there.
kaguya's second nonspell can be redirected, as demonstrated in the replay. Just go off to her side and stay focused.
LSI: same as hard mode but with more stars.
Hourai Jewel: SPell practice, spell practce, spell practice. Learn the gaps, or if you have 1 life in stock bomb at the edges of the screen. Here's my only capture of it ever:
