Need help with Registax

Hello all:

I got my Toucam and have started fidiling with it. I'm still recording very small images (no barlow) with the camera, and trying to get used to the motions of the object in the viewscreen--a difficult task to say the least at high magnification.

My question: how do i get registax to process one avi composed of multiple frames? I record four or five 20 second avi's, and put them together into one image. However, I do a single point alignment, which works fine until the next clip starts, which Saturn is back across the FOV. The single point alignment has a stroke and I can't get any further. Any suggestions?

Guy,

I generally just use one 60 second AVI (about 1800 frames at 30 frames/second); however. if you are concerned about planet rotation or too much image movement, you can process the 20 second AVIs individually and then combine the four or five resulting images.

Here is an image of Jupiter using a single 60 second or so AVI.

When I do multiple AVIs, I usually get a warning box
that pops up when the next AVI starts. Something
about it not finding the alignment. There are some
options to click in the pop-up box. I think it is
the left option to manually reset the alignment --
you click that option, then click the center of the
planet, and it goes happily on its way.

Do you get the pop-up warning message?

Guy,

There are two other utilities you may want to investigate to help with planetary imaging when the planet is moving from side to side in an AVI. The two utilities are AVI2BMP and PPMCENTRE.

AVI2BMP takes an AVI and extracts the frames into individually numbered BMP files. Once you've done that use PPMCENTRE.

PPMCENTRE reads a series of BMP files and rewrites each BMP whilst centering the planetary object in the middle of each new BMP. The result is a series of BMPS that have the planet essentially motionless in the middle of the each frame. You can align and stack the BMPS directly in Registax very easily since the planet won't drift at all.

Just google PPMCENTRE and AVI2BMP to find the downloads. Both are free.
