Very noisy 224mc

wargrafix

Hi all, I find that my planetary recording using the camera to be very noisy. my camera has the 1.3 board. Saturn will normally use 350 gain

and jupiter I try to use less, but there is a fair amount of noise.

OTA is 9.25 sct

saturn is very dim and you need high gain such like 300 or 350

so just capture more data and stacking then you have less noise

Once I heard the voice of a famous imager who said that a big amount of data (several minutes of captures) is mandatory for a good image of Saturn. And he talked about a telescope bigger than a 9.25.

Besides, in my operating conditions, the average seeing forces to push the processing so that the noise rises up easily. When this happens, it means I need much more data than those I captured.

So, keep on.

Good luck

Yes, Saturn is not like Jupiter, Jupiter is bright, and you can using lower gain and lower explosure, but Saturn need longer explosure and higher gain. the cost is got more noise, and need more frames to reduce the noise.

In most circles, that's still a dang good image of Saturn.
