Hiya Steve, get registax 5. you can load the avi into it, the software then stacks the individual frames into 1 final image.

Some typical settings for the moon are:

Exposure 1/100s, Gain 50%, Saturation 50%, Gamma 25%, Brightness & Contrast around 50%, try to ensure highlights are not overexposed.

A lot will depend on the capabilities of the camera. I tend to try and keep the gain and gamma as low as possible, get over 50% gain and the image starts to get a blue cast and odd lines showing up.

Hi. Thanks for all that .At the top of Astro CApture you

have got ,TYPE -Light-Dark-Bias-& Flat .What does this

mean. The web cam i am using is a moded mono 840k

The scope is the Vixen 102mm .This Astro Capture is

a lot easer to use than K3CCD Tools.

Light - is the image data you're capturing

Dark - is to remove noise and dark current

Bias - is to remove the bias noise of the chip

Flat helps to remove vignetting, dust in the optical train etc.

For the moon, I've only ever used lights, you're running at a high frame rate, and fast shutter, so I don't think the effects that you're compensating for have much bearing on the resulting image (I could be wrong ..) The Dark's, Bias and Flats are used in Long Exposure imaging, which wxAstroCapture is also capable of.

because i cannot find any info on what settings to use

at all .Can you explain to me about the long exposure

Steve, Sorry I can't help on LX settings on wxAstroCapture, I've never done it. I use my SLR for LX captures... However, have a look here for some info (from the DeepSkyStacker help) on the various frame types. That and on here is where I got my info from for the various frame types and how to take them, for my SLR anyway...
