Great closeups with the C11, Alfred: love the detail and contrast.

Roughly stitched 2 proms images. Unfortunately the clouds disrupted the proms session.



Enjoy it.

Very nice images Alfred, would you mind sharing some imaging details like fps, exposures, gain?

Hi Dennis,

Camera: Basler acA1920-155um
For disk images, I captured 2000frames at mean frame rate of 141 FPS, exposure of 7mSec and Gain 22105. Stacked 300frames.

For Proms, captured 900 frames at mean frame rate of 19.99FPS, exposure 50mSec and gain of 16,421, stacked 150frames. I am not really sure if I should use longer exposure time for Prom capture. Any suggestion?

Imaging session: 7:45 am to 8:15am.
Location: Singapore, slightly above the equator
Cheers.

Thx for the infos.
The proms i would image with the same exposure as the surface details.
With 50ms i would be worried about completely losing the resolution of the c11. At least in my varying seeing conditions.
