DMK vs Lumenera

Hello Guys,

Just curious, which is a better camera the DMK firewire or the Lumenera?

Thanks,

Chris

Hi Chris,

In all honesty i think there is very little in it. Both seem excellent (from my own experience the Lumenera is superb.)

Best Wishes

Thanks for the info Eric. I'll await your results. I'm sure the Lumenera will be more sensitive because of it's larger pixel size but I was wondering by how much as one would also have to increase power to compensate for the large pixel of the Lumenera.

Regards,

Chris

Thanks for the very interesting discussion.

The color Lumenera seems like a great camera - unfortunately my current Mac laptop does not have USB 2.0, nor is there a software choice at the moment to drive the camera in Mac OS. Fortunately the excellent webcam operation program Astro IIDC for Mac OS will operate all the DMK cameras. The firewire cameras that I have used do not require a separate power source other than the power supplied through the firewire cable. BTW, Apple makes it's own thin and flexible firewire cable which is a great upgrade from the usual thick rigid cables.

Funny thing - for this apparition of Jupiter the only way i have been able to capture decent images from my location (we kiss the air here when seeing is 6/10) has been with LRGB process, relying mostly on the red filtered images for luminance. I have settled on an exposure of 60ms which requires a download speed of 15fps. Even at this slow shutter and frame rate I have many more usable frames in red than in white light, despite the full spectrum advantage of faster shutter and download speeds.
