It's not so much the stationary foreground as the stationary camera. As the stars have moved (the Earth rotated), their relative geometry has changed in the image. This is down to the way a rectilinear wideangle lens projects onto the sensor. The only way around it is to put the camera on a driven mount, or at least use a narrower field of view.

Not really, I've had them stack before (30 x 25" exposures) and this shouldn't be any different, the warping on the edges is beyond me - original exposures were sharp as anything.

Any ideas why I cant get RBG or anything to raise colours when I stack?

Like a lot of astrophotographers, I get repeated questions on how to do things that although may seem simple, I have to remind myself that they were once beyond me...

So last night, I sat up all night and stacked some images in Deep Sky Stacker, taking screenshots all the way and writing down what I did as I went.

Hopefully this can answer a lot of questions and get the new blood in the game well on their way to adding to the richness of images proliferating amateur astronomy.

Have a crack, enjoy and let's see what you new folks can do!!! YEEEHHARRR!

P.S. There have been a number of enquiries on this thread about star-trail software and problems. This article is written about DEEP SKY STACKER. If you are having issues with startrails.de, StarStax and other programs, please start another thread where others may be able to help you. Please keep your queries in this thread on topic.

Baz.:cool:

I just tried clicking on the link in the first post of this thread... I found it not working. Is that what Gutterscum was reporting back on May 16, 2013?

It's really old mate and honestly, I've been out of the game for so long that you might be better off letting this one die. I've moved on to bigger and better projects...

Lots of better tutorials out there now.

That is a very good question, one I wish I had thought of now since I asked a question last July.

I just now checked, and this thread HAS been "un-stickied" which I am assuming was done because of your question here!

Thank you!
