Yesterday we held our second Hubble Hangout on Comet ISON, specifically on how to get Hubble data of the comet. Max Mutchler and Zolt Levay were onhand to discuss some of the processing issues and locations people can go to on the web to obtain the files. Dr. Bonnie Meinke was available to talk about the science behind the comet.
Now, I can't imagine that this would be true, but if you're one of the people out there who -- amazingly -- doesn't have time to watch the hangout in its entirety, I've gone to the trouble of highlighting some of the more salient points.
So while I'm trying hard not to be upset that you can't watch the whole thing, here are the bits you won't want to miss:
- Bonnie caught us up on the latest news of ISON with an amateur image taken by Bruce Gary from an 11-inch telescope in Arizona.
- Max makes a good point about the difference between an image and data.
- Max on why Hubble isn't a point-and-shoot camera
- Scott gets a post on Sky & Telescope about ISON and how it's already disappointing
- We want to make sure we point you to the RIGHT data products that make understanding the data as easy as possible.
- What's wrong with getting the raw data?
- What are data pipelines?
- Is it more work to produce these images from Comet ISON than for, say, the Hubble Deep Field?
- What is DS9? A viewer for FITS images.
- Where can you go to get the data?
- Zolt talks about how to combine images to make color composites
As always, we had a great time doing the Hangout. I would encourage you to check our Hubble Hangout page, where future events will appear as they are scheduled, or follow the Hubble Space Telescope Google+ page to receive notifications.
Below are all the links we discussed in the Hangout:
For non-professionals interested in playing with cool Hubble FITS images in general, Max has also been maintaining a broader HLSP collection of Heritage FITS images.
And many more HLSPs (mostly NOT moving targets) are linked here.
