Guiding woes


Recommended Posts

I've been trying to figure out what's up with my guiding , the 1st night was hideous , the 2nd time wasn't better and the 3rd time was killing me. I checked the level , balance and adjusted my sidereal track rate from .5 to 2 per another fellow astronomer . It's starts out real nice but, then it turns ugly and I just can't put my finger on it. Help me loungers?P1020182.thumb.JPG.e304dbbbc294638ba3431fa5a312477b.JPGP1020183.thumb.JPG.31ac6280f687fe89fc2fca8fede81fe0.JPGP1020191.thumb.JPG.3253c283f864d36b9a2321103ad6e0e8.JPG

Would be useful if you post your guide logs. But my first observation is that you are guiding at close to 5'"/pixel. Achieving an RMS of better than 0.2 pixels is not easy. But there's probably mechanical issues involved as well.

And as others have said, if your images are ok then why worry?
