My Canon 350D (Rebel XT) doesn't work with my last version of BackyarEOS, therefore I work with EOS Utility from Canon and I use ZoomBrowser - old version 1.3 that has the ressource to zoom the image up to 800 x.

I use the spikes to check the focus. If it is ok, the spikes are equal and thin. Nevertheless, some times this procedure doesn't work well, because there aren't a star with spike near the object target. Or it is binary. Or I have only a bright star near. The focus with bright star is a little different of the faint stars. Faint stars needs better focus.

And now, a repro with better work with HDR. As I found another galaxy, IC 4828, I increased the field to show it.

I rotate the canvas vertical and horizontal to be at the same position of the previous post, that has good resolution.

Because of large amount of lights I had problem with vignetting, and I haven't flat files for sensor without IR filter, yet. I haven't, also, a good custom white balance to reduce the redish appearance of photo. This was problem in processing the 20 lights.
