QHY5L-II Pixel problem??

[johnnyt123]

Hi Everyone.

I had a go at planetary imaging using my Celestron C8 and QHY5L-II colour camera.

i encountered 2 problems:

first i couldnt adjust the green saturation bar and it was always stuck at about 50% and the subsequent image was purple in colour.
Secondly i could actually see the black lines that separate the pixels in the final image after stacking in registax and applying some wavelets.

Has anyone come across this before and does any one know how to overcome these issues?

I am at work at the moment and will post up a photo of saturn and mars showing these problems later on.

Thanks.

John

here are the shots i took of Saturn and of Mars last night

saturn has been colour balanced but looks very dull
Mars colour has not been adjusted

if anyone knows why the pisels are so visually obvious and how to correct this i would greatly appreciatenit also the colour issue too

thanks

I'm no expert, but it looks like you're not debayering. Check you have debayer enabled and that it is using colour type GR (iirc).

You may have over done the smaller wavelet sliders causing the pixel problem?

Hey guys.
Raymond I only get these pixels like this when I use this camera no matter how much I overdo the wavelets.

Dunk I will try to see if debayering is possible and I will try your suggestion the next time the weather permits. Sydney has been horrible weather wise lately.

Thanks.

John, debayering is something you do in post processing, assuming you were capturing in colour. Look for the debayer option.
