Autoguiding problems...

[E_ri_k]

Hey guys, I have been stuck on this one for a while now, and cant work out what is going on.

In the past autoguiding my G11 has been no problem, until recently I have been getting star trails on my longer 10 minutes subs. I noticed that PHD is making quite large corrections, with values as high as 600-1000.

I thought my polar alignment may be out, but I checked it with PemPro, and visually, and I had no significant drift for 8 minutes with the barlow and crosshair eyepiece.

My mount is well balanced, I am going to try the later version of PHD, or try guiding in Maxim DL when it clears up.

Has anyone had a similar experience?

Thanks, Erik.

not sure what the issue is, but give Guidemaster a try. I never had any issues with this. If you have the same problem again, then at least you know it's not the software.

Hi Guys,

I have a HQY5v, as an autoguider and when I try to calibrate it , it keeps saying (star has not moved) I have changed the calibration settings, the second exposure, but it still comes up with th same answer, and as I'm a novice at this it getting to be annoying, my mount is a HEQ5 upgraded, has anybody else had this problem.

What are you using to calibrate? A finderscope or another scope, such as the ST80?

It could possibly be that you are trying to guide on a hot pixel rather than a real star.
