  • Star Party 2/18/2017- Oak Canyon Astronomy Group


    Update: 2/17/17 - We regret to say that due to the expected storm this Star Party has been canceled. Please stay tuned for information on Oak Canyon's March star party. 

    The Oak Canyon Astronomy Group has returned!   Sponsored in part by SkyWatcher and Software Bisque (many thanks for donating equipment!) and FOCUS Astronomy Outreach and run by the generous volunteers that have kept the club going.   Join OCAG for the Joe Napolitano Memorial Astronomy Outreach star parties each month.  Due to inclement weather the January star party was canceled. The first star party will be February 18th, 2017.   Here are the details:

    • The subject of conversation on the 18th will be Observing the Night Sky with focus on general observing tips, orienting yourself with the sky and finding key objects.
    • Set up is from at 4pm-5pm.    Please be respectful of this setup time.  It has been allocated to get set up done before dusk when the need for flashlights is minimal.
    • Starting at 5pm outreach telescopes will be available to the public.
    • Event ends at 9pm.  Because the star party is held on Oak Canyon Park property, we ask that you be prepared to depart in a timely manner.

    Oak Canyon star parties are held at 5600 Hollytree Dr. in Oak Park, CA 91377 at the Oak Canyon Community Park.   Outreach telescopes will be set up on the upper parking lot on the northwest end.     Oak Canyon Community Park is in a suburban setting and while the skies are dark, these monthly star parties are designed to offer an opportunity to the community to get up close and personal with the night sky.    Children with supervision are absolutely welcome and seeing the moon, planets or a star cluster through a telescope for the first time can be an awe-inspiring experience.   Outreach volunteers have kindly lent their equipment and are happy to answer any questions you might have.  Don't forget, running lights only as you approach the lot if you're arriving after dark.

    We'll see you out there!

  • Coronado Personal Solar Telescope - VIDEO

    The Coronado Personal Solar Telescope or PST was an innovation at it's introduction.  A small, self-contained h-alpha telescope that didn't break the bank.  Perfect for outreach and travel the PST is a 1 angstrom 40mm dedicated h-alpha solar telescope that will bring out the incredible detail of the Sun's surface.   This small but mighty telescope is also available in a double stacked 0.5 angstrom version that will further refine surface details and bring out solar flares as well.

    An h-alpha filter produces a false color image of the Sun in a brilliant orange-yellow color that we typically associate as being the Sun's 'color'.   H-alpha filters and telescopes are an eye-opening and thrilling way to observe, image or video our nearest star and an up-close way of watching live solar events like the upcoming 2017 Total Solar Eclipse.

  • Nexdome Q&A

    How well does the Nexdome withstand wind? 

    Per our tests, the dome resists up to 50 miles wind WITHOUT the wind lock and so far we had a report of 80miles wind WITH wind locks. Photo attached. About sand storms, I am sure that fine sand can get into the dome through the gap between the dome and walls.

    Does the Nexdome withstand high temperatures and prolonged exposure to
    the Sun (UV)?

    The NexDome has been tested for extreme temperatures of - 40 to + 55 degrees
    celsius. Compared to the same class observatories NexDome is has the
    coolest inside due to the gaps between the dome and walls which air can
    travel through. Also, NexDome has the best UV coating in the market called

    Can the Nexdome be locked and secure from entry?

    Yes the NexDome door can be lock from outside and shutter from the inside.

    How does the Nexdome rotator motor work and can it be controlled by software? 

    Yes, we debuted the dome rotation motor during NEAF 2016 and the shutter
    motor is now available. Yes, they can be controlled

    Do you have interior images of the observatory with pods installed?

    Yes! Check out our friends at Ostahowski Optics.

    Here is an image of the Soul Nebula, taken with the Prima Luce DSLR camera and 300mm Sigma APO camera lens at f/2.8.  An IDAS light pollution filter was used.
