cinematography Siemens Star Chart

[BlueSapphire]

Does anyone know where i can get a Siemens Star Chart for Back Focus Adjustment?

I am putting a lens on my new camera for the first time.

How big does the chart need to be?

Thanks

Heh, I had to look up what that was.

B&H sell several:

(Ignore the obvious "star maps" for star-gazing)

Thanks! boy those are pricey.. but i guess if you change lenses alot it might be worth the investment.
