Hi, I've recenty purchased the above camera and need some help using it! I tried it on Mars last night. The only way I can get colour out of it is by using the yuy2 setting. I tried the y800 with the y800 codec and got B&W, also when I used this setting at 60 frames the avi has a fine grid over it. Can anyone help me with these problems?

Hi I've got the DBK41 and went through a similar process. The grid you can see is the Bayer matrix in the camera. From memory the y800 is a B&W format, but you can apply the Bayer matrix colouring to it in Registax to restore the colour (I'm not sure how to do this in avistack). I do it this way to get the fastest frame rate from my camera, otherwise the DBK41 only gives me 8 fps. The other trick is to make sure you are writing out RGB32 or yuy2 to get colour.
Quite a bit of fiddling involved, but worth digging around the imaging source forums for help as well.

I'd suggest using Firecapture to debayer any SHORT Y800 AVI's (smaller than 1.8 GIG) &/or Autostakkert for big Y800 files. Those 2 programs use the best available algorithms to debayer, where as Registax uses a low quality QUICK algorithm.
YUY2 + unspecified is still my favorite way to capture but 30FPS limited. Use it in good seeing; Y800 for average or less seeing.

Thanks for your replies,
asimov, I have been playing around with Autostakkert and it does a good job. Does it also de-rotate the frames? Also how do you re-align the channels. Registax can do this in the wavelet section?

Good question. I don't know if AS!2 derotates or not. It's certainly not a manual option that I've seen yet. It might do it automatically though. Drop Emil a line to find out. He can be reached here: http://www.astrokraai.nl/contact.php
Yes RGB align can be found under functions on the wavelett page of Registax.
