How to make a telescope’s automatic alignment more precise?
I have just purchased a new Meade Etx 90 telescope, and I’m loving it. However, it seems that whenever I do an “automatic align” and then use the computer go to a target such a planet or galaxy, the puts me in the vicinity of the target, but not directly on it. I have to do a few minutes of searching before I actually find the target. Is this because I am not properly aligning the telescope? Or is the computer just not precise enough to land right smack in the middle of a target? Im trying my best to follow the directions in the manual/dvd that came with the telescope as closely as I can, but it doesn’t seem to do the trick. Any ideas?
Three things will help. Make sure that the tripod is level. Make sure that you have the correct date/time/location/time zone entered into the computer.
Also, get to know how to identify the brightest stars, so that you have the option of NOT using “automatic align” but can instead align on particular stars manually. I suspect that a complete automatic alignment is not going to be bug-free. If you can initialize your alignment manually, I think you will have better results with the GOTO as long as you use a low power eyepiece when going to an object, as this is more likely to have it in the field of view.
The freeware Stellarium will help in learning the sky.
