Hi Katerina, the etx 90 is a good scope and has handled the test of time well. Me personally I havn't owned one but I know a lot of people that have over the years and most would not sell them , so that says something.?
Any way whats your favorites in the night sky ?
The etx90 only has 90mm of apateure so will show only the bright deep sky stuff, but there is plenty in reach of a 90mm scope.
What I like and have seen many times is real good views of the planets and especially the moon, these scopes are awsome for this.
Also the goto on these is now bullet proof and easily upgradeable via
Meads web site . so go for it .
Thats my 5c worth so go ahead and enjoy,
Brian.
