Here Are Some Stars to Take Our Minds Off Donald Trump

I feel like I need a breather from the “real” world I allegedly inhabit at the moment. So here are some stars:

I have no real excuse for posting this, but it is the result of an experiment and all experimental results should be published, right? Last night I went out to a semi-dark area for one final practice session with my tracking mount before I head off to northern California. I decided to see how well the tracker works with the lens at full zoom, and this is the result. The lens is zoomed out to 220 mm (600 mm equivalent) and the exposure time is about a minute. I have no idea what part of the sky this is. I just pointed the camera upward and took pictures at a few different spots.

Anyway, the tracking is not bad! There’s very little apparent motion even at full zoom. However, one minute is as far as it can go. I tried a frame at two minutes and it was clearly streaky.

Four of the stars have little plumes. Can anyone tell me what these are? Something real, or just artifacts of the camera? They all point in precisely the same direction, which makes me think they’re artifacts of some kind, especially since they don’t show up in an identical picture with a shorter exposure:

This picture has an exposure time of 9 seconds and there are no plumes. The arrow points to the star at the very bottom of the upper picture, which has a noticeable plume there. Any ideas what this is?

UDPATE: A reader suggests the plumes are vibrations from bumping the camera at the beginning or end of the exposure. That’s entirely plausible given my general ham-handedness around delicate equipment.

AN IMPORTANT UPDATE ON MOTHER JONES' FINANCES

We need to start being more upfront about how hard it is keeping a newsroom like Mother Jones afloat these days.

Because it is, and because we're fresh off finishing a fiscal year, on June 30, that came up a bit short of where we needed to be. And this next one simply has to be a year of growth—particularly for donations from online readers to help counter the brutal economics of journalism right now.

Straight up: We need this pitch, what you're reading right now, to start earning significantly more donations than normal. We need people who care enough about Mother Jones’ journalism to be reading a blurb like this to decide to pitch in and support it if you can right now.

Urgent, for sure. But it's not all doom and gloom!

Because over the challenging last year, and thanks to feedback from readers, we've started to see a better way to go about asking you to support our work: Level-headedly communicating the urgency of hitting our fundraising goals, being transparent about our finances, challenges, and opportunities, and explaining how being funded primarily by donations big and small, from ordinary (and extraordinary!) people like you, is the thing that lets us do the type of journalism you look to Mother Jones for—that is so very much needed right now.

And it's really been resonating with folks! Thankfully. Because corporations, powerful people with deep pockets, and market forces will never sustain the type of journalism Mother Jones exists to do. Only people like you will.

There's more about our finances in "News Never Pays," or "It's Not a Crisis. This Is the New Normal," and we'll have details about the year ahead for you soon. But we already know this: The fundraising for our next deadline, $350,000 by the time September 30 rolls around, has to start now, and it has to be stronger than normal so that we don't fall behind and risk coming up short again.

Please consider pitching in before moving on to whatever it is you're about to do next. We really need to see if we'll be able to raise more with this real estate on a daily basis than we have been, so we're hoping to see a promising start.
