I bought my son the 70mm Astro-Gazer and the software is designed for PC.. Where can i find in 2 cd-roms for a mac computer

Channel loc will do the job. One twist will do wonders. about 1/2 turn.

Copy the CD Rom files to a large thumb drive. Setup and install the programs from there. If that does not work, contact Verbatim customer support: http://www.verbatim.com/contact-us/

The screws can be found at any hardware store, the eyepieces can be bought at many on-line retailers. Here is one:

The software is nothing but a planetarium program and you can download a better one for free here:

The spreader (tripod) is NOT really needed but will help stabilize the tripod-- you can make one that will work just fine out of wood.

Clear skies!

The general rule is 50 times aperture. Your scope is about 2.5 inches-- so 50 times 2.5 or about 125 power--- MAXIMUM and only when the sky is very stable and transparent.

Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.

The main scope is probably also designed this way, but many amateur scopes now come with an erecting prism or eyepiece attachment that turns the image upright. You may have fitted this and not realise that it is an add-on, and that it is un-natural for an astronomical scope to display upright images.

That little scope will NEVER be able to use the 4mm with the 3xbarlow, just too mmuch magnification. The maximum possible magnification for ANY telescope is about 50 times aperture.

Your scope is about 3 inches so 150 power is the maximum.

No sorry. This is just about the worst telescope you can buy. We get more complaints on that brand than just about any other. You might find something at a well stocks hardware store that you can use to fix it???

But why even try to fix it. Buy your son this telescope instead.
