There is such a huge difference in the noise from the 550D at different temps. My sensor generally sits at about 10 degrees above ambient during an imaging run - so the last few nights it has been 25-26 degrees - but during summer is more like 37-38 degrees. The noise is much easier to deal with at the lower temp.

I will dig up some darks and post them.

That is a cracker of an image by the way !

Guess who can stack RAWs now . Now you've done it to yourself. Really set the standard. Fantastic shot Nettie. I agree you have handled the noise really well. Excellent detail. What process did you use to sharpen? It looks to have done a nice job.

She didn't give in without a fight though, did she Paul.
My colt didn't give me this much curry when I broke him in.
But stubbornness pays off. Makes the victory all the sweeter I think.

25X5 is a good noise kill ratio. Well done JJJ. I like the way you have refrained from hitting the 'lets go nuts with the saturation here!' button.

Great stuff.

more saturation = more noise
It looks pretty in pastel.

Very nice JJ, you have captured a lot of the bouter nebulosity considering the short subs. Looks like this camera will be OK after all......................... That has to be one less worry.

Keep them coming.

Looks pretty nice JJJ. Colour could be a little more saturated, but not too much of course.

Stars look generally good with good colour and pretty reasonable shape.

I like the image scale of the first image, and am not keen on the second, some minor problem spoil the look of that image. I would like to see another 2 to 3 hours of data on it. Then boosting saturation will prevent noise. Certainly one of your best to date. I am really looking forward to seeing more of your images.
