Gamma Virginis with rainbows

What was the altitude of the star? If it was low toward the horizon, atmospheric dispersion may have done this. At low angles, the atmosphere does the same thing a prism does - it spreads out the spectrum.

Auto Guiding Question

Posted By Ron Wodaski

There is more to guiding than meets the eye. It's not as simple as attach the guider, find a guide star, and go. To get good guiding, you'll need to:

* Test your mount to see how well it performs in tracking
* Tune your mount for best performance in guiding (backlash being the number one thing here).
* Test your mounts' ability to guide accurately
* Learn the ins and outs of calibrating your mount for guiding (what makes a good guide star; what kinds of error occur, what they mean, what to do about them, etc.)
* Spend some time guiding with your mount to learn about it's quirks and limitations.

Since you have an SBIG camera, you already own a good manual on guiding. I wrote the manual for CCDSoft, and the chapter on guiding goes well beyond the abilities of just CCDSoft, and gets into the subjects described above. For a more thorough treatment (as well as lots of other useful stuff), get yourself a copy of my book, "The New CCD Astronomy."

LX200 mounts vary considerably in their ability to guide effectively, so it's well worth spending some time to see just what your mount can do.

That's a really excellent image. Really sharp, perfectly guided, and processing is really nice.

Nicely done; a dee pimage of a dim customer. The only issue is the gradients; mastering that will come with experience.

NIce shot - it's got lots of detail, and you've gone long enough to capture the many dimmer stars in the cluster.
