  • 60 years ago today, but yesterday in Australia

    Thats a pretty mixed up title for todays post… But you get that over here pretty often……

    Let me explain………

    60 years ago today, Edwin Hubble took the first official photos through the Hale Telescope. Please read about it on Scotts blog. (And dont forget to bookmark his blog and pop back once a week to keep up with whats been going on up on the mountain. Its sort of unofficial required reading for all the Docents. Besides which, Scott is a great writer of all things Palomar!)

    Yesterday in Australia, but here today, it’s Australia day.
    I really wanted to make some Auszi food to bring to work, but we had a pretty busy day yesterday and so by the time we got done with what we had to do it was about 9pm and I really did not want to start cooking at that hour. Perhaps next year.
    Amy is wearing my Bundy Rum t-shirt to school. Not sure what Terry has planed. Probably nothing. I totally bailed on the food and clothing thing. I know, I am letting the team down a bit.
    The only thing that I can say to try and make up for it was that Freddy and I ordered a bunch of food from the Australia shop over here and its due to arrive today. We got milo, custard power, cordial and a bunch of other things. So tonight will be a real Australia celebration in a house in Temecula.
    I will blog the list of all the food we miss from over there, its surprising.
    The list came about because cousin Jo wanted to know what food we missed, it got us thinking. She also asked what food from here we would miss if we went back. It was an interesting exercise to think about. (If I remember I will try and take a photo of our little food purchase before its all ‘et).
    Anyway, its a day of history, both here and there…….
    Well done Hale and Hubble.
    Ozi Ozi Ozi Oi Oi Oi !!!!!


  • Its time……

    Every two years (give or take, depending on the weather), the mirror is removed from the Hale Telescope, striped off and given a new coating.

    This is one of the better YouTube videos I have seen on the process.
    The other place to see the action is the Palomar webcam.
    I am pretty sure that Susan will be taking photos (and video I hope) of the process this time around (Scott is giving a talk in Corning (and looking at their library for information on the pouring of the two blanks) so he cant take photos this year)).
    Look for a link when they get that processed.
    The dome floor is closed to everyone except Palomar staff working on the mirror.
    As a result, there are no docent tours this weekend, there might be one of us in the visitors gallery to answer questions…..


  • Journey to Palomar.

    Wow, what day……. Fantastic. I think the best thing to do it just go over it as it happen…….

    I got up on the mountain at about 9:15. I was a little late because there was a photographer taking photos of the bikes on the way up, I was disappointed that I missed out last time, so this time I stopped and got his business card. I am going to buy the photo and will post it here…….
    So, once I got up there, I went to the gift shop to pick up my nice new docent name badge and then headed up to the dome.
    There were only two people in there, so the lady came over and let me in. Turns out that the two people were Todd and Robin, the husband and wife team that made the film. That was pretty neat to meet them like that.
    Before long, Scott arrived and I started helping him bring chairs out of his car into the freight elevator at the bottom of the dome…… Sounds boring right? Hah! This was the Hale Telescope! It was a cloudy day and there were clouds coming in the open door we were walking in and out of!!!! It was very neat looking. While I am carting chairs I was smiling ear to ear!
    We got a bunch of chairs up, but Todd was wanting to get the screen set up, so Scott let me tackle that one. Phew, it was a pretty big job, but you have to remember I was putting it together right under the telescope. I really did not get distracted, but it was a really neat environment to be ‘working’ in.
    We got the screen up and then hung some curtains on the side, it really looked super. (Link to all photos at the end of the blog).
    By this time a whole bunch of people had showed up, along with the food, so it was a chance to unwind a little. I was standing at the side and a guy walked up and we started chatting….. Turns out that David had worked as an electronics tech at Palomar for about 28 years. He had retired about 8 months ago. Anyway, we got talking, and he has some fantastic stories to tell……. He also took me to look at the ‘phantom telescope’ that used to drive the dome (photo in album)….. Trust me, this was VERY cool and VERY exciting.

    So the movie is introduced, but Scott and Dan (the superintendent) had planed to slew the telescope over every ones head just before the movie started, it got a lot of ooooss and aaaahhhsss.

    The movie was great. I did not take enough clothes and got really cold half way through, but it did not slow me down none. I learn’t so much about George Ellery Hales life, it was just amazing. I never thought I would get into history like this, but I am really drinking in all I can on the topic.
    Todd and Robin have done a great job, and they should be proud of their work, its a great film.

    After the movie something rather rare happen. They opened the shutters and left them open. Even Jean, the telescope operator was taking photos (she made the point that if they do open it in the day, she is asleep, but she also made the point that they do not open it and leave it open very long usually).
    I did what every self respecting telescope nut would do……I went bizerk with the camera. I took over 200 photos. Its not normally that well lit so I wanted to make the most of the occasion. Most of the photos are in my web album, I have a few that I have not put up because they are just slightly different angles of the same thing.
    I even got to go into the operators room and saw where Jean sits and where the astronomers sit. (See the photo link).

    After a while they shut the shutters and it was time to take everything down and go home.
    It only took a moment to pull the screen down, get the chairs out (lots of helpers) and pack things up.
    It was a bit of a cold ride home. (Have I mentioned how much I miss my bike gear?). But I was glowing. It was just the best day. Just amazing. I’m still on a bit of a high from it.

    The photos are here. Just click on the arrows above each image to go forward or back. (Click on ‘Slideshow’ for the best full screen view).

    On a related note, be sure and check out this guys blog entry of a special tour he and two friends were given…. He puts it better than I can in a lot of places.


  • Daylight saving ends… tomorrow Im excited.

    Just a heads up that day light savings ends this weekend in SoCal.
    If you have a clock set to our time zone, it ‘Falls’ back an hour at 2am tonight.
    It means that there will only be 5 hours difference between Oz and USA.
    In the past, this has been a good thing as it meant that I could get help from the tech support group at Opto 22 longer each day.
    Now that I am here, and the time difference is more about catching up with friends and family, I am not sure its going to work out as well.
    For example, one thing that is going to not work out any more is my Thursday morning hook up with my electronic peer group in Ballarat.
    It used to be that when I got up at 4:30am here, it was 9:30pm there, perfect. But now its going to be 11:30pm there, far too late for them, and there is no way I am getting up at 2:30am (although I am often awake at that hour, I find it best to still stay in bed!).
    Im not sure how it will affect my other ‘phone home’ schedules, most of the people I call are pretty flexible and I can catch them at home or work, so we will just have to see how it goes.

    Tomorrow I am heading up to Palomar for a very special event.
    I will ride the bike up, because its not a tour, Freddy will stay at home (with the kids).
    Its going to be pretty amazing to see a movie about the telescope under the telescope…… You can rest assured that there will be a blog entry about the day as soon as I come back to earth!


  • pod’ie training.

    As most of you know, with in the first few weeks of arriving in Temecula, I attended a meeting of the Temecula Valley Astronomers. It was there that I met Susan, who would have thought that meeting her would lead to such an amazing opportunity……. When we first met, she told me about the Friends of Palomar. I joined up pronto, and Susan got me on the list for a tour and regular readers of my blog (all 3 of you) may recall that first tour.
    Back then, I honestly thought that would be as good as it gets……
    But, no, on my second tour we saw the Hale Telescope slew and the shutters open!
    Wow, so, surley, THAT was as good as it gets???…..Well, no, apparently Susan was conspiring all this time, and last week I got an email ‘formally’ inviting me to sign up to become a ‘Palomar Observatory Docent’ (pod).

    First things first. Whats this docent thing? I had never heard the word in Australia…… Well, according to the free dictionary.com, docent means ‘a teacher or lecturer at some universities who is not a regular faculty member or a lecturer or tour guide in a museum or cathedral’.
    Clearly it is the latter of the two meanings that applies to us here.
    So, a Docent is a tour guide………….
    Did that sink in? I took me a moment…… I was being asked to become a tour guide for Palomar Obervatory….. !!!!!!!!!!!!!!!!!!!!!

    Woooo whhhhhooooo!!!!!!

    So, I filled out the paper work, and last Sunday was the first time ever that two tours were offered on Sunday’s. (Clearly a big part of my acceptance). Freddy decided that she would come up with me.
    Sunday, mid morning, we headed up the mountain. We decided to drive, but we will try taking the bike a few times as Freddy gets a little queasy in the car, but I suspect she will be fine on the bike.
    We met up with Mike (tour leader for the day) and Susan, who was working in the gift shop.
    The idea was that we just tagged along and saw the tour from ‘Joe Public’ point of view. I wanted to get a feel of what it was about…. So Freddy and I were tail end Charlie to Mikes two tours.
    It was not long and we had about 15 people for the first tour. ($5 adults, $2.50 seniors and $2kids). We set of on time, and here is a little taste of what happens……..
    The first place we stop is just up the walk way from the visitors center. Its the first time you see the 200” dome.
    The group pauses and we talk about who ‘owns’ and runs the observatory, the size of the dome and a little of the other telescopes on the site.
    We then walk up to the Palomar Testbed Interferometer and we talk a little of how it works and what a light year is.
    Next is George Ellery Hales bust just inside the entrance to the 200 inch dome. We talk about his life and achievements.
    Up the stairs, note at the top the cut away section of the dome wheels.
    This is where you enter the public viewing gallery. Usually there are some people there that are not part of the tour, but they quickly stop talking and start listening (and hopefully are so impressed they go to the visitors center and sign up for the next tour!).
    Here you talk about the pouring of the mirror, the grinding of said mirror, the light path of the telescope and what it was like to use the telescope when it was first commissioned.
    You then open the door to the dome floor and collect every ones tickets. (Hey, sorry, no freeloaders!)
    (Sub note, I love hearing the oooo’s and aaarrhhhhs’ when people walk into the floor, its so much more spectacular to see the telescope right there, rather then through the glass of the gallery. (Worth the price of the tour right there)).
    Once on the floor you talk about the weight and ballance of the ‘scope. We have a small model that we get someone to drive and it makes it clear how the telescope moves around the sky.
    Next its up to dome platform. You can really see the scope now.
    We talk about the different parts of the scope and dome, the walkways, elevators and so on.
    Next, its out onto to the dome catwalk for a stroll around the outside of the dome, we point out the different domes, markings and mountains.
    Lastly its back into the dome to talk about the Friends of Palomar and answer any last questions.
    Then, you lead everyone back down to the floor and out to the gallery.
    Tour over.
    Mike has set me a nice high bar, hes a great Docent, I look forward to working with him and the other docents.
    The exciting thing is that Freddy has decided that its not the worst thing I have taken up and she wants to join me as a Docent and be the crowd control on my tours. So we will be ‘working’ together when we do it, that was unexpected (I honestly thought it would be too geeky for her, but she sees how excited I get. Also she saw how beautiful it was up there, and secretly, I think she has been smitten by the beauty of the 200” is as well).

    So, the burning question is……. Would take a tour if this guy was the docent of the day??
