Using AstroTortilla to Plate Solve Objects

AstroTortilla

I recently downloaded a plate solving program called AstroTortilla, which is a program that corrects GoTo alignment and centers objects you are trying to shoot.  Before using this program, my GoTo alignment would vary from night to night and if I am shooting the same object, I would have to crop out a portion of the object since the mount did not slew exactly to the position I had the night before.  After I successfully installed and set up the program, thanks to this amazing tutorial, I tried it out on the Pelican Nebula (IC 5070).  After plate solving the nebula, it was a clear night so I decided to image for a couple hours until the clouds rolled in.  Under the full moon, I can only image through the Hydrogen Alpha (Ha) filter so I went out the next night and collected more data on the Pelican Nebula.  The AstroTortilla program performed flawlessly each night.  As you can see in the image below, the only cropping will have to do to this image is due to drift, which is an insignificant amount of image loss.
