Comment:
For my my first test stack trying my Milar 6.5cm/4.5 I used a very small ForgetMeNot that has been kept reasonably fresh in my fridge for several weeks.
The flowers are very tiny, only a bit more than 1mm in diameter.
The stack is made from 24 images with a UV-pass filter stack: S8612, 2mm + U-360, 2mm.
The magnification is 2.4x on the sensor.

A closer crop with no additional sharpening.
