ok! I can do that!
Let me elaborate on my blunt/brief/comment..
"when I was a wee lad........." j/jokin'
Seriously though...The 70mm diametre refractor on your list would be ok for terrestrial viewing, but no good for astronomy....too small man. The short focal length your going to get plenty of false colour. Really only a toy for astronomical use! (IMHO)
The 2nd one ....I dont like the 'false advertising' for starters (that's if you copied N pasted that info in here?) 70mm aperture & 90mm diameter?? That's rather confusing for a newbie! If it (IS?) a 90mm diametre scope, at F13....It's gonna be better for astronomical purpose's I guess.. RE: the 675X mag!!??
What can I say? That's rubbish!
I dunno....I think for 400 dollar's, there's better choice's out there.
What about a 4.5" to 6" reflector...with an image inverter for terrestrial viewing?
