Jupiter 13/11/11 - 2nd attempt at planetary 2 years on

[troypiggo (Troy)]

Just realised it's been over 2 years since I first attempted planetary imaging. Been tinkering around with my gear and had a crack at Jupiter again the other night.

The colour may be a little off on this, but not worth me spending too much time on it. Anyone know what has caused the square pixelation, looks like the Bayer matrix showing up? Camera is DBK21 and was using a 2.5x powermate on 10" Newtonian. I have a 5x on order for better image scale.

Shot using the Y800 codec, so it appears B&W on screen and pixelated. Had some fun and games trying to get colour balance right. Tweaked the channels so that none were saturating and all approximately similar levels during capture. Still, K3CCDTools was dropping a lot of frames.

Processed in Registax 6, but followed this v5 tutorial as closely as I could: http://stargazerslounge.com/primers-...-tutorial.html

The resulting image was far from correct colour balance, so adjusted as best I could.

hi Troy. never used a DBK, but it sure looks like a Debayer problem. Otherwise, good detail. Regards Ray

Thanks for that. Just read the other thread about the DBK21618 and noticed ponders posted some links that I'll go through now. I did capture as Y800 then debayered with R6 in that prefilter window.

One thing I wasn't aware of and not sure if that caused the issue, is the limit of 1/60 That Clayton mentioned. Reckon that could cause the above?

Rather than go through it all again Troy, there is a thread on this problem on CN http://www.cloudynights.com/ubbthrea...fpart/all/vc/1
Which may help

Thanks mate. Bit more reading for me.

Hi Troy - one other thing that may be worth trying is to run a low pass prefilter to stop R6 from aligning on fixed pattern noise as well as the image features - have found a blur of 3 or 4 in R6 is best for my system when trying to stack noisy data. Regards Ray
