i asked one girly friend why she thought it was boring, and not at all fun or interesting. her reply?
she thought that telescopes looked very "phallic" and gadgety, male orientated, and not at all feminine.
i got the impression if she could find a telescope in nice pastel shades with those absolutely awful frangiapani car window stickers, it might be more approachable.
That said, my better half has a very keen interest in it, and loves gazing through the eyepiece.
