Quote:It is also worth checking that your Questar telescope declination dial is aligned correctly with the axis of the optical tube assembly. On a perfectly level table point the optical tube upward in a vertical position and put a bubble level on top. You can double check this with bubble levels that also work in vertically. The declination should read 90 degrees. In my case it does not. I was surprised that it was about one degree out (checked with two different levels). There is no way to adjust this that I know of. It does not really matter, as long as you pick it up. When you dial in the declination coordinates, just offset the reading by the degree of error.
Quote:Accuracy is a wonderful thing, but not a preoccupation with me.
