Patrick Moore has been recorded as saying that the minimum aperture which
should be considered for someone taking up serious amateur astronomy is 6" in a
I am sure Sir Patrick has ample experience to justify his statement.
Therefore if you want a newtonian reflector of 6" aperture, I have heard many
good comments regarding Orion Optics Telescopes, the Europa range has a 6"
Again I am no expert but if I were looking a telescope to begin with I think I
would consider something like this, however it is below the £200 budget you
have to play with, unless you can pick up a good second hand one.
I understand that buying second hand telescopes also has pitfalls of which you
must be aware.
Given your budget and the previous advice given by others, I would rather
invest in a good pair of binoculars and put off planetary observations to such
a date when I could afford a telescope which would be suited to this purpose.
Hope this helps.
