Space: Secrets and Surprises

In the September 2018 issue of Sky & Telescope, we explore all manner of mysteries in space. What was it like when we first peered through Venus's clouds (and why should we go back)? How did dunes form on Pluto? Where did young stars near our galaxy's central black hole come from? What was that strange object scientists found in Lacerta in 1929? Polar align your scope using a camera and spreadsheet. What diaphanous delights does September's sky have in store? Check out our observing picks for the month, learn about lunar librations, and see what stars Lacerta has in store! Plus, these celestial targets are fun to find with the right telescope under suburban skies. Enjoy these and other stories in the September 2018 issue of Sky & Telescope.

Can't get digital August or September issue. The only option seems to be Zinio, but it doesn't recognize my Email or password, but when I try to set up a link to the digital issues, it says the info I give it is already linked to someone. Help again.

Per my previous message about not finding the digital edition(s) of Sky & Telescope - I found it. In the past, I would receive an email with a link, but haven't received it recently. I couldn't find digital access through the S&T home page. Finally went to Subscriber Services and found a digital access link there. Everything is copasetic now except for the perpetual rain & moonlit cloudy skies at night here in Chesapeake Beach.

And in detail: First you login. Then Subscribe / Subscriber services / Access current digital issue. Click top icon 5 from right (the arrow over the tray) and the latest issue is downloaded as pdf. Much better than the new service through the company Zinio.

I am still awaiting my print copy here in the UK.

I sent S&T and email about this but haven't had anything positive. Please, can you sort this out?
