Saturn 15-04-07

Hi all

Saturn from yesterday evening in okay seeing, but very poor transparency.

Quite happy with this apart from the ring artifacts. I've left them for now, but I'll probably end up smoothing them out.

Hi Chub

I normally put the details on the pic. This was a RRGB image taken with a mono Lumenera Infinity 2-1 camera and a C11 at f27, which is about 7.5 metres focal length. The Infinity is not really a specialist planets cam as it has a large array of smallish pixels. It is ideally suited for lunar/solar, but is pretty versatile and also does okay on DSOs, especially if the pixels are binned 2x2. I took this M13 last Autumn shortly after I got the camera (I think it was with an Orion ED80).

And I am a real novice at deep sky. I'm sure someone who new what they were doing could get some great results with this camera.

For a real novice that's a mighty impressive Glob. image Nick. I don't think that you are a million miles from some great DSO snaps based on the evidence so far.

Great images Nick. ....er, anyone, what does "binned 2x2" mean? :?

[Kaptain Klevtsov]

Binned 2X2 means that four pixels are grouped together to form a bigger pixel. This reduces the image size (but not the FOV) by 2 in each direction, hence 2X2. The gain is that each superpixel gets a signal from four normal pixels which are added together. This makes the binned camera four times more sensitive so the sub-exposures only need to be 1/4 of the time required for an unbinned sub-exposure.
