Finder on Celestron Astromaster 70.
I visited a friend tonight who had asked me to have a look at his Celestron Astromaster 70 refractor (70mm diameter, 900mm focal length), as he was having great difficulty with. The telescope was pretty average , but did yield some beginner views of Jupiter and Saturn that would wow newbies.
But the Star Point finder defeated me. It had two glass reticles about 40mm apart, and when I flicked the switch, the middle of the closest reticle had an illuminated dot on it. I couldn't locate anything with it, regardless of whether I used one eye, or two eyes as the manual states should be done.
The only way I can see this gadget working is if the front reticle was also illuminated, and having both front and back dots lined up with the object one is aiming at.
Could someone please advise whether there should be an extra illuminated dot on the finder, and thus that my friend's unit is not working properly? Or whether just having one dot on it is actually correct, and that I just don't understand how it should be used?
Regards,
Renato
