Just tried out my new TIS DMK618 camera on Saturn. Seeing was poor, so image is RRGB with no storm detail showing and R6 rejected most of the frames, so the noise is up a bit. R and G were taken at 60hz, and show no sign of the ringing artefact that spoils the 098 based DMK cameras at this framerate. That was the main reason for doing the imaging - looks like the new camera works really well and the extra quantum efficiency of the 618 chip is really useful. Regards Ray.
Correction, just had problems recording Jupiter at 60Hz, so had another look at this data - although it is reported to be 60Hz, there aren't enough frames in some of the avi's and it looks like this was actually 30Hz. will post again, when I get some sleep/work out what is going on. Verdict is still out at 60hz..
Paul, thanks for your comment - this was a much better result than the seeing suggested
Peter - I would also like to get to the bottom of this - the camera sure is effective, but it is not yet clear exactly what it is doing at high frame rates.
Don't know if this will help; last year I had problems with my DMK recording at a set FPS, I would set it at 30fps, but after 10 seconds capture I did not capture the required 300 frames, but about 150. It wasn't until I started using the almost empty partition of my C drive instead of the 75% filled area that it recorded at the required FPS.
I don't know it this lines up with your issue, if not disregard it.
hi Lester. Thanks very much for the tip, will try it out as soon as I can offload some of the stuff on the drive (it's >80% full). Could explain why the camera is behaving for some users and not others. Regards Ray
