Blog Post 2 – Due Friday, September 7th

I’ve linked the text we read and discussed in class yesterday – The Power of Light. Choose one of the prompts below to respond to from that text
1. Choose a technological advance from the text. What does that technology teach you about light? What questions does it raise for you? How is the technology significant?
2. What characteristic of light that you read about was most striking or interesting to you? Why? What is its significance? What questions does it raise for you?

Also respond to the questions below:
3. What is your understanding of how starlight is produced? What forces are at play? What is happening inside the star?
4. What do you find most fascinating about light and why?

5. Post an image of both sides of the Number Sense Problem set.
6. Post your plan for astronomy over the coming few weeks. Who will you be working with? When will you go out? What object(s) do you hope to image and why?
7. How is the semester going for you? What are your strengths? What are you struggling with? What are you hoping we get to in the coming weeks?

Find an Object to Image in the Night Sky

Use the neave planetarium site to find an object in the night sky to image.

Cross reference the objects in the night sky with the Messier Catologue or NGC catalog to find something that will be up. The object must be brighter than Magnitude 10 and bigger than 0.5 arcseconds.

You can also look at prominent stars – Magnitude 3 or brighter – to image. Each one of you should have a hit list of stars and deep sky objects that you’re interested in imaging.

Your process should be the following:

  1. Spend some time individually finding objects you have an interest in imaging. Any object larger than 0.5 arcsec and brighter than magnitude 12 will suffice. Find three to four objects.
  2. Convene with your partnership – groups of three to four. Decide on which of the objects you’d like to image. Get that signed off by Brian. You should do a max of four objects. I’d probably recommend two would be better because you’ll be able to collect more data the fewer the objects you plan to image.
  3. With the group, plan out what type of wide field image you’d like to capture. Do some research on wide field imaging. (constellations, milky way, timelapse, star trails)

Good luck!
