    Default 2017 Total Solar Eclipse



    I have begun making preparations for next year's total solar eclipse. I have seen many partial eclipses, but never a total, so I am really excited. I have a question about viewing the eclipse, however. I know that during partial phases, I will need to view it through a filter (I have mylar white-light full-aperture filters for my telescopes), but once totality hits, will the light be too low to see through a solar filter? Is it safe to view it naked-eye? If I want to take a photo, can I safely point the camera at the Sun?

    Sorry for the noob-sounding questions, but since totality only lasts a couple of minutes at best, I want to make sure I make the most of the time I have and do things right.

    Okay I have never enjoyed one either but I do know once you get totality naked eyeball mark I is perfectly fine. I personally would not bother with the scope once totality hits. You will have 2 minutes and 23 seconds to enjoy what many describe as the oddest thing you will ever encounter in nature. Dont waste that time trying to look through an eyepiece

    Tom - the answer to your question is yes, you can look directly at the Sun during totality. There is no need for filters for your eyes, cameras, or scopes. If you intend to capture the event in any manner, I suggest you prepare your script and practice it until you are completely comfortable with it and have worked out any bugs. Automate it as much as possible and let it run, and sit back to enjoy the show.

    Alternatively, you can consider the 2017 eclipse as a dry run for April 8, 2024, which will also cross the States and will have a total phase that lasts over 4 minutes - a relative eternity compared to the 2+ minutes in 2017. Me, I intend to enjoy 2017 fully and hopefully get to the 2024 event as well. The closest I have come was the March 7, 1970 event from Chatham, Cape Cod. We were close enough to see Baileys Beads, but were not allowed onto the wildlife refuge just south of us, which was in the path of totality. Still, the sky turned amazing shades of purple in a 360 degree twilight, the air got noticeably cooler, we could see birds going to roost, in all a spectacular not-to-be-miissed event!

    My wife and I are planning a trip to see the eclipse. My record of eclipses is saw one (Kazakstan, USSR in 1981) and clouded out (Falmouth, Cornwall, UK 1999). We are planning a trip that puts us in the Tetons, near Teton Village, on eclipse day. I thought it would be an ideal opportunity to see tourist attractions that we've wanted to see; Mount Rushmore, Devil's Tower (Since I saw 'Close Encounters of the Third Kind' in 1977), Yellowstone NP, Badlands NP, Carhenge, my wife found a Minuteman missile site that allows tourist, Little Bighorn Monument and Deadwood; to name a few places. I'm an amateurs astronomer, my wife isn't, but loves wildlife. She's 'authorised' me to buy a solar telescope; I'm looking at either a Lunt or Coronado. We live in UK, so this is going to take some planning. I've started putting together a 'Google Earth' itinerary. We've already booked accommodation for the eclipse period and near Yellowstone.

    starlogborg- thanks for asking these questions. i have been searching threads all day looking for one that asked what i was wondering about. but to take your question a bit further: i know leading up to totality i will be using my solar filter and i know how my white light solar pics will turn out. (i have photographed venus and mercury transits). but my real question is- once totality in happening- will anything show up or will it just be blank? i will have my scope set up to track the sun but im curious as i am photographing the eclipse i will have partial- partial-partial-blank- partial. i guess i could remove the filter during totality for "ring of fire" but that goes against all safety logic. lol.

    i appreciate any feedback.
    Happy Hunting!!!

    In looking at the script EO (Eclipse Orchestrator) made, it prompts for filters as follows. It basically is 20s each side of totality.

    PLAY,C2,-,00:00:20.0,Sounds/filters_off.wav,,,,,,,,"Filters off" voice prompt
    PLAY,C3,+,00:00:20.0,Sounds/filters_on.wav,,,,,,,,"Filters on" voice prompt

    During totality, it's doing this:

    I personally plan on letting this thing go auto and looking up with my eyes, but this may help. After camera model, it's: Shutter speed, something, ISO...

    You have to know your aperture ratio for the scope or simply aperture for a camera lens.

    eclipse orchestrator works for the pc.

    there is a free version and you can edit the script or the a bit pricey paid version with more features
