|☄ Moon Telescope Size Detail ☄|
However like with most things in life, the more expensive the telescope is the more detail you will be able to see. But when it comes to astronomy there is also another factor you should think about. That is the more detail you are after, the size of your telescope will also get larger.
So there is a choice you have to make.
Are you going to go big and limit your mobility?
Or are you going to go smaller and be able to set up your telescope pretty much anywhere you want?
The rule of thumb for a best size of a telescope is set by most astronomers to be a 10 inch telescope. This is because even though a 10 inch telescope is rater big, it is still small enough so you can take it in your car and not being to heavy to set up once on site. The size difference if you think about it 8 inch vs 10 inch is not that big and the weight is almost the same. The new Collapsible truss-tube / flextube design of Dobsonian (DOB for short) telescopes make them very compact and you can fit a 10 inch telescope in the back of your van without taking anything apart.
Now personally, I would really recommend the 130mm or 5.1 inch telescopes that are available too, these are very mobile, not that big, affordable price and easy to setup. You will get a good telescope for your money. But it really depends on what you are going to do with your telescope and what you are looking forward to see.
The moon in the picture have not been taken by any of the telescopes but is a NASA photo. However if you are looking to get similar detail you most likely are looking at a 10 to 12 inch telescope with clear skies and little light pollution. But do keep in mind that what you see in photos are not always the whole story, a camera is only as good as it's ability to capture light and the human eye is still way more sensitive, meaning you will probably see even better detail yourself once you have everything set up and in focus.
