If it might interest you, I've picked it up again with my Celestron C9.25 from Milan :) . In these sweltering days the air is very calm even if NOT very transparent. But in the observation of planets, atmospheric calm matters more than transparency. Days with a lot of wind are ABSOLUTELY not good for taking photos of this type. They would be extremely blurry.

Yes, a single shot with a Canon with 50x optical zoom, 50x digital zoom that doesn't pixelate, and 100x that pixelates a bit.

It's a friend's camera and we never expected a result like this

You know, we wanted to buy a telescope near my house that sells used items, to see the sky XD. Can you give us some advice?

Hi Sisyphus,

certamente. It depends on what your initial budget is.

I can only tell you that today, with about 100 euros, you can find really well-made used instruments.

To keep it light and simple, you could look for an 80/400 refractor, meaning an 80mm lens diameter and a 400mm focal length.

You have no idea how many things can be seen with 8 cm under a truly dark sky.

While even from the city, with 8 cm you can see a lot of details on the moon and on the planets.

Now, if you want, you have until September to take a look at Saturn. It's in the early evening.

The largest Telescope in the World.

I just learned that the summit of Cerro Armazones, a 3,000-meter high mountain, was blown up with an explosion in Chile. A million tons of rock fell to allow for the construction of the largest infrared lens in the world, part of the European Extremely Large Telescope (EELT).
The lens has a primary mirror 42 meters in diameter. In this area where the sky is always clear, it will be possible to catalog images more defined than those of the Hubble space telescope in orbit.

I don't know whether to be excited about the telescope or scandalized by having blown up the top of a mountain... moreover, I doubt that the Hubble exists

Thank you so much for the advice, as soon as I am a little free I will go for a spin and let you know

On October 7th, instead, Uranus will be in opposition, so the planet will be illuminated by the Sun... but the distance from Earth is so great that it will only be possible to see a small blue/green dot; but even that would be something, wouldn't it?

I also found the news about the mountain top blowing up "strange"... All that's left is to see the results, although I imagine it will take years.

Hi Lapuska,

si, it is a small billiard ball if observed visually with a medium/large telescope.

Today, however, several details can be distinguished in photography. Using cameras that work primarily in the infrared.

Here is an example obtained with an excellent amateur telescope with a 35cm diameter.

...but there are more details than I imagined, actually, for an amateur telescope! beautiful and interesting

Thank you, foster12
