Re: APOD: Cathedral, Mountain, Moon (2023 Dec 25)

The photographer states he used a telephoto 500mm lens and has also posted a video clip on his Facebook post showing the camera as it was taking the image. It all appears consistent with the photo.

Re: APOD: ISS from Wallasey (2019 Apr 06)

Re: the last question, yes. The ISS makes one rotation per orbit so the cupola is always aimed at the Earth except for specific reasons when they temporarily change the orientation. There's a number of us amateur astro imagers on Twitter that manually track ISS passes with telescopes then post image...

Re: APOD: Rotating Moon from LRO (2018 Mar 18)

Anything in existence that would show the locations of all objects on that surface ? Ranger, Surveyor, Apollo, etc I like to use the Lunar Quick Map http://target.lroc.asu.edu/q3/ . It's VERY thorough, but you can select your overlay layers... "Anthropogenic Features" will show landers.

Re: APOD: Roadster, Starman, Planet Earth (2018 Feb 10)

But it really does look a little fake. Why the 'halos' around bright objects? Did they use an iPhone to take the photo? These 'halos' are an artefact of the the exposure limits of the camera trying to balance a mostly dark (space!) field of view with very brightly lit planets and spacesuits. Also i...

It was the cubesat market I was mostly thinking of.

I did a search, using 'clearing house' and 'sorting' but was inundated by Harry Potter and the Sorting Hat references.
What was your search?

Just "satellite launch service", a few links down :D

This might be the time for some enterprising person to set up a clearing house, seeking room on launches and offering them to universities and businesses. For a fee, of course.

Re: APOD: A Double Eclipse of the Sun (2015 Mar 22)

I'm having a difficult time proving this alignment happened. Where was ISS Mar 20 2015 9:20 UT? Somewhere other than this photo. Using Stellarium and the location given, these photos were taken at 09:06:13/14 UTC. All three objects were aligned to match Mr. Legault's result. http://www.eaglekepr.co...

As one who's frequently tried (and mostly failed) at airplane window astrophotorgraphy, this is an amazing capture. I've never had a smooth enough flight!

A double congrats to Ben Cooper with back-to-back APODs! Just wish I could have been there myself to see and photograph the event.

Re: APOD: The Umbra of Earth (2011 Dec 15)

Edit: I'm assuming the camera is tracking at a sidereal rate, since we see stars as points. Since the image is a composite of 5 images of the moon, and since there are no stars in the "end" photos of the moon (due to the shorter exposure required to capture the mostly lit moon) I'd expect...

And they would be partially right. The final image used Photoshop Elements 6.0 (it's all in the metadata!)

Re: APOD: Sunrise, Moonrise (2011 Jan 06)

I suspect that the zoom lens shifted (or was misadjusted) slightly between exposures, resulting in the actual Sun images being made at something other than exactly the same focal lengths. Agreed... although I wouldn't try to use an artistic compilation of manipulated images taken with an imprecise ...

Re: APOD: Sunrise, Moonrise (2011 Jan 06)

beautiful. but odd that the clock tower and the smoke from the various smokestacks doen't change in the timelapse... maybe the eclipse images are superimposed over a still image of the town...? The whole of the background image was taken at sunrise (which is why the lighting is warm/orange-ish). Ea...

Re: APOD: Eclipsing the Sun (2011 Jan 05)

A corrolary to this photograph is that occupants of the ISS must have observed the eclipse. What a sight that must be from space! I wonder if the ISS (or any other orbiting humans) have ever witnessed a total eclipse of the sun? :?: It's happened a few times, this is just the first one that came up...
