Thanks.

That's what I think, that the secondary mirror is not aligned. However does the centering of the secondary mirror depends on having the length of the arms of the spider EXACTLY EQUAL or can the secondary mirror still be aligned by collimation regardless?

When I properly collimate this Celestron Newt would the double/blurry images disappear when I view terrestrial object? IE as a means of testing the collimation prior to using it again at nighttime.

The pricing is very competitive even when compared with Andrews', unless its a fake, which I doubt.

Thanks again.
