The iconic Aricebo radio telescope is to be decommissioned. Arecibo Heartbreak: Iconic SETI Dish Will Be Demolished Due to Risk of ‘Catastrophic’ Collapse

I'm curious what other people think about this whole controversy. Long story short some people want to build a telescope on a site in Hawaii, other people say site is sacred, and the entire discussion has been dipped in the "But America colonized Hawaii" baggage. Me personally "OMG WHITE...

https://phys.org/news/2018-03-nasa-next-generation-space-telescope.html I think we should all march if there is any further delay to the launch. Mankind depends on the results of James Webb and our escape to the stars, because American politicians cannot be relied on to do their duty as...

Saw this while reading an article at phys.org. Slooh allows Members to remotely control professional-grade telescopes in both the Canary Islands and Chile. It's easy to take deep space photos and share them with others! https://www.slooh.com

Over in Zooniverse Talk*, there's a ~3 weeks' old thread "I was wondering if the Santilli telescope can be used in the zooniverse or to classify antimatter stuff and antimatter galaxies?" (link). Yesterday, a quite new someone with the handle sferwnhafs6tggs posted a bit of material on this...

An add for a telescope seen on Ebay http://www.ebay.com/itm/Celestron-C6N-reflector-optical-tube-/200731262697?pt=US_Telescopes&hash=item2ebc83fee9 Unbelievable! You've had me since I left the factory. A couple of years ago, I was the only thing you could think of. You couldn't wait for it to...

My darling wife suprised me with a new telescope. A Nexstar SE8 goto. After some false starts with weather, finally got to put the beast through its paces. The optics are truely outstanding, and everything went together with a minimum of fuss. We went with the goto function because I moved to...

I'm thinking I'd like to buy a telescope, and learn to use it. I'd love to be able to check out the planets. I've had limited experiences with telescopes, but each time I was blown away by the experience. Any suggestions of a telescope in the $300 range? What's the least you (yes you)...

Bill introduced to honor Galileo H.RES.1269 Title: Commemorating the 400th anniversary of the first use of the telescope for astronomical observation by the Italian scientist Galileo Galilei. Sponsor: Rep Tiberi, Patrick J. [OH-12] (introduced 4/15/2010) Referred to the House Committee on...

Today is, apparently, the 400th Anniversary of Galileo's telescope. According to Google, who have a nifty version of their logo to celebrate. Just thought you might like to know. ;)

I don't have any experience with telescopes, and I was wondering if this one was any good. Amazon is giving me $15 off, so it's only $30. It will be mostly used with my kids as they get older.

There must be a few people here who get out their 5 inch at night to play with? Some of you may even be lucky enough to have 6, 8 or even 10 inches! February looks to be another astronomy special, with our solar system putting on some great displays - a penumbral eclipse of the moon, several...

Let's spend tax dollars on something that probably won't end up niggling our consciences: Arecibo Observatory, the world's largest radio telescope and the source for the SETI@home data that your computer analyzes, faces massive budget cuts that will END its ability to continue the search for...

Did you know that we still do not understand the mechanism by which ground glass gets polished? I was an amateur telescope maker back in the 70s, and back then learned that we really had no idea how the final polishing of the glass works. And so today I wondered; Has this been solved...

Anyone else use this service? I bought a SLOOH 500 minute card at Wolf Camera before Xmas. I think it's a wonderful service. Between this and my own telescopes, I'll never get any sleep! :D

For my 30 year giftie from the city, I chose a tabletop telescope, mainly for the alliteration. I've never had one before and I'm quite pumped. Any suggestions for good Web sites (aside from Bad Astronomy) to help me in my heavenly research?

Having recently acquired an interest in looking skyward, I'm giving serious thought to buying a telescope. I mentioned this in an earlier thread, but at the time, I thought maybe a good binocular set would be a more practical choice. Since then, I've decided I don't want to be practical ;) A...

OPTICALLY GENERATED WEATHER PROBABILITIES Per scientific studies performed by amateur astronomers (of course), the duration of the cloud cover/rain/snow is usually a function of the aperture of the objective mirror or lens of newly-purchased optics. The derived formula is as follows: T = D/10...

I'm about to move to a house which backs onto lovely dark fenland, and I'm thinking of replacing my Tasco rubbishy, rickety, okay-for-a-ten-year-old 'my first telescope' telescope with something a little more respectable. But I don't know much about telescopes. So does anyone have any advice...

Astronomers are preparing to build the world's largest telescope that could be 100 times more powerful than the Hubble and will peer back to the very beginning of the universe. The new TMT (Thirty-Meter Telescope) will be the first of a new generation of massive Earth-based telescopes that...

I've got a telescope that has two objective lenses. One of them is labelled K10, and is higher magnification than the one labelled K20. I've figured out (or think I have!) that the K stands for Kellner, but can't figure out the way the numbers are derived. Any ideas?

I'm looking for a hobby. But not one that requires a PhD, or a second career to finance. Building a telescope kind of looks fun. There are different levels of involvement. From throwing together off the shelf parts, to grinding your own mirror for reflective. Anyone ever do this? Is it...

Link Link to the swedish 1m telescope currently showing pictures from the Venus transit.

I'm getting a telescope. What ones would you recommend? I want one that is uncomputerised, can be connected to video and still cameras, will pack-up into a case so it can be taken on trips.

The field is open to those of the backyard stargazer/astronomer/astrophotographer persuasion. SCOPES: If you can pick it up and move it all (even if it takes a couple of trips), you're in. Pier-mounts and the like go in Pro class. Be it scope or just good lenses on the camera, let's see what ya...
