    Macastronomer started the topic T Cor Bor in the forum Meetings 1 year, 6 months ago

    After Randy’s talk I decided to start shooting T Cor Bor. Can you pick it out in this photograph? Here’s a hint: the brightest start in this image is Epsilon Cor Bor.

    Love it! We should start a new thread to share images. Seeing what everybody is doing is wonderful—and inspiring! Keep ’em comin’!

    Nice pics. How many subs and how long? What’d you use to process?

    Keep’em coming. I’m jumping into the game astrophoto game soon and it’s great to see what others are doing.

    Until I save up and get a scope and astro-camera, I’m planning on putting my Canon R50 (not an ideal astro-camera but it will do) on my EQ6-R Pro and see what it can do.…[Read more]

    Nice. Thanks.

    For clarity:

    NELM = Naked Eye Limiting Magnitude
    MPSAS = Magnitude per square Arc-Second

    I think I’ll make a chart using the info on that link and see if I can look at the sky and get the same result.

    <p style=”text-align: left;”>I’d like to get set up before dark (9:00-ish), but I don’t always get out when I think I will. Regardless, it won’t be long after.</p>

    Can’t make the public outreach, but I am planning on hitting Root River to do some observing.

    If anybody wants to join me, I’d be happy to have the company.

    Macastronomer started the topic What's your astronomy story at the moment? in the forum General Discussion 1 year, 7 months ago

    This forum is a bit cold and dark… it doesn’t have to be. Or maybe it does… If we don’t communicate here, maybe we should jettison it from the website, like two droids escaping a compromised Corvette class starship towards Tatooine, or Spock’s casket shot into deep space. The RAC page could be strictly informational… an internet billboard.…[Read more]

    Macastronomer replied to the topic It was a Glorious Night for Astronomy! in the forum Star Parties 1 year, 7 months ago

    Thanks for sharing about the dark sky meter. I’m eager to see what we get out of it over the year.

    Macastronomer started the topic How do Photos get submitted? in the forum General Discussion 1 year, 7 months ago

    How do photos get submitted to the club’s web page, to the Facebook page? How do articles get submitted for the newsletter?

    Thanks.

    Here’s a pic of Randy setting up his giant scope. 🙂

    A friend of mine liked this photo better, and I have to agree—so I’m posting it as well.
