Making a mosaic

If you want to image a larger object with a small chip CCD it inevitably leaves to one thing: Mosaics. My first attempt turned out fairly well (I made a 6 panel mosaic of the Rosette Nebula), but did take a good bit of figuring out, aligning, and minute stretching adjustments to balance the panels once they were processed and aligned. I tried various ways to create the mosaic and found that Photoshop was the easiest way out of the programs I currently have.

I was going to specify all the steps to make a mosaic, but instead I created actions for my new action set to do this for both a 6 panel and a 4 panel mosaic (I might expand to a 9 panel as well - havent decided). From there its just a matter of rotating and continuous slight stretching with levels and curves around and around until they all merge together seamlessly.

Here is my result:
