Photo Op: Penumbral Eclipse AKA Shadow on the moon

  • Oct 18, 2013 · 6:45 PM

*** Update Sept 25*** Trying to find a place to meet on a Friday evening where a good number of people could gather in time for this is not easy. Because of that I have changed it to a "Photo Op" so the greatest number of people could participate. This means there will not be a set place to meet. Find a place, grab your camera and tripod and shoot the moon! Once you have some nice images post them here!

For those who have never shot the moon before here is a good starting point: ISO 100, f11, 1/125sec. Using your longest focal length lens mounted on a tripod for maximum stability. If you have a VR lens remember to turn the VR off, it causes vibration that will blur your images when on a tripod. That should get everyone in the ballpark! I look forward to seeing some great moon shots!

*******

What is a Penumbral Eclipse you might ask? Well looking on the inter webs and at the link below it looks to me like a shadow will be on the moon. I sure there is a more technical explanation (ok you can look it up!) but that works for me. Lets just say that part of the full moon wont be as bright as it usually is. 

I'm not shure where to meet for this so I'll be looking for a location. Mark you calendar anyway! Sorry this a Friday night but the earth's shadow waits for no human!

    FYI, there will be a solar eclipse Sunday morning (remember the time change). More here: <http://www.sfgate.com/technology/businessinsider/article/How-To-Watch-Sunday-s-Rare-Hybrid-Solar-Eclipse-4948149.php>; and here: <http://www.timeanddate.com/eclipse/in/usa/washington-dc>;.

    Unfortunately, based on what the timeanddate website says, it looks like our area will only be able to see the tail end of it (partial eclipse), in the south-southeast portion of the sky right at sunrise.

    • Elizabeth W.

      The UMD Observatory will be open 1-5pm TODAY (Sat 2 Nov) to handout solar filter glasses (to safely observe the partial eclipse). The observatory WILL NOT be open for the eclipse as we simply don't have a good enough horizon. However, I will likely be set up near the USMC War Memorial to get some shots. https://listserv.umd.e...­

    I used a Cannon 60D with a[masked]MM lens with a tripod. I do not think my pics came out that great but I will post them anyway.

    I did notice that my hand held photos came out slightly better than when I used the tripod. I had VR off when mounted on the tripod so I must have done something else wrong there....

      Michael, it sounds like live view may be the way to go on that body, from what these folks are saying: <http://www.dpreview.c...

      Great info, camera shake was definitely my problem, as I also forgot my cable release, etc, etc :o(

    Would have been more fun if I was shooting with some fellow meetup members. But is was a beautiful night.

    • Ron C.

      Dana, There will be a group shoot at the Tidal Basin that evening. If you do not have the invitation from MeetUp, EMail me directly, if you do not have it or cannot find it, and I will send it to you. Also, let me know if you wish to join me on a future late night DC photo shoot from other locations.

    I got a few decent photos but yhe moon was in and out of the clouds. I was at the tidal basin next to the MLK monument. The moon was rising closer to the Washington monument side of the basin. I used two different lenses..Sigma[masked] and a Nikon 28-300. I then moved over to the Lincoln memorial and took photos of the reflecting pool and Washington monument. Unfortunately, I did not run into any other photographers.

      I used a very good tripod, Induro CT314 carbon fiber that supports a load of 39 lbs. The Opteka Gimble head supports 30lbs. My camera and lens weighed a little over 6lbs.

      October 20, 2013

    • Jay

      Dana, it sounds like a very nice tripod & head! Balancing the lens sounds like it may well be the missing piece.

      October 20, 2013

  • John C.

     If you use a tripod, check for the following:
    Make sure that it is sturdy and has a solid has a solid head.
    Use a cable release (in a pinch you can use your camera's self-timer, though you will likely be limited to thirty-second exposures).
    Beware of wind vibrating your tripod and softening your image.
    Avoided using the vertical column extension on your tripod. The more extension you use, the less stable your tripod becomes.

  • Jay

    Next time I try to take a photo of the moon, I'm going to try setting the camera to pre-release the mirror and see if that makes things any sharper. (See, e.g., <http://www.kenrockwell.com/canon/5d.htm>;)

    • Andy

      Were you using a tripod and a canle release or self timer ?

      October 19, 2013

    • Jay

      I used a tripod and cable release. Live view is not an option on my camera body. Curious to see what difference, if any, pre-release would make.

    I will be at the DC monuments. I will set up at the basin next to the MLK monument shooting across the basin to the Thomas Jefferson monument.

      Hi Dana, I was thinking about going to the Netherlands Carillion (near the Iwo Jima) to shoot, but if the postion of the moon is going to be better from that point, I may come down there. Do you know where the moon is suppose to rise?

      Hi Tonya, I am sorry about missing your comment. I did not check again until today. Next time you plan to shoot at the monuments, let me know, I will be happy to shoot with you. I love shooting there.

      October 19, 2013

  • Dan G.

    Anybody going back out to try tonight, just to practice and see what you can do after trying last night ??

    October 19, 2013

    • Jay

      Weather tonight doesn't look promising where I am, but I may try again Sunday night, very late. From <http://aa.usno.navy.m...;­, it looks like the moon was never above 20 degrees when/where I was shooting last night. It's my understanding that low angles mean a lot of atmospheric disturbances that will degrade image clarity. I may try around midnight Sunday, when the moon is higher in the sky, although I'll be in town instead of the boonies - not sure how the city lights will affect the moon photos.

    I have a Cannon T2i and use the 55 -250 lens but none of my photos came out good. I missed the boat on this one.....guess I need to practice taking photos of the moon. :(

  • Nona

    excellent...

    October 18, 2013

  • Dan G.

    My 200mm Kit zoom lens didn't do all that great of a job on seeing the moon, nor did the amount of moisture in the air help with getting a clear shot. So I found some really dead and creepy looking trees to try a Halloween look. I'll post some pictures later.

    So I am at my house now looking at the moon. What time is this suppose to happen again?

    October 18, 2013

    • Elizabeth W.

      Its already ended... A penumbral eclipse is not noticeable like an umbral eclipse... Please read my previous comments that had more details.

    We're at the Netherlands carillon. Too cloudy right now.

    October 18, 2013

  • Jay

    Hi, I realize there is no set place for this Meetup, but if anyone has a specific time and location in mind, and wouldn't mind some company, please let me know. I've tried once before to photograph the moon and it was quite challenging for me to get any photos that were halfway decent. So, I wouldn't mind an opportunity to do this with someone else there to bounce things off of.

    I have no obligations Friday eve., so I can travel. Let me know the time/place you plan to be, if you're so inclined. Thanks!

    I have arranged with Maryland's Point Lookout State Park to allow me and one student to use the park for photography tomorrow evening. If others want to join us, please EMail me directly at [masked]­t and I will increase the number. Otherwise, the park closes at sundown to all but those fishing.

      Ron are you familiar with the point lookout area ? A friend told me he saw eagles out there regularly. Do have any insight into where and when they are down there. Could this be a separate trip at a later date ?

      Hi Theresa, ISO 200, 1/250 sec f11 is where you should start.

    Hello all. I am a new DSLR owner and new to the group. I have never been to a meet up and wnated to know if a time and meeting place is in the works so I can get the best experience ever on my first outing. Please let me know if a small group would like to meet at a location and what time..thanks.

    October 13, 2013

    • Vincent K.

      Hi Michael, for this Meetup there is no set meeting place. The info above should get you in the ballpark for setting up your camera.

    Haven't seen any new information on a location. Did you get my message a week ago, about trying Observatory Park in Great Falls. It normally closes at dark but will be open that Friday night.

    October 6, 2013

    • Vincent K.

      Hi Dan, There is no formal meeting place. With this being a Friday evening and many people working, it would be very difficult for a majority of people to make it from work to a location on time. Anyone who wants to participate can set up anywhere they want to. Now with the government shutdown, if it continues, Great Falls is closed making it unavailable for a Meetup location.

      October 7, 2013

  • Vincent K.

    If people would like to get together in small groups in different places post suggestions here. Otherwise take a chair into the yard and make some photos!

    Concerning the Maximum Eclipse, what do these different times mean: "Oct 18 at 11:50 PMOct 18 at 7:50 PMYes"? The later hour makes sense...but the earlier one??? And, what does the "Yes" mean.

    September 22, 2013

    • Vincent K.

      Hi Ron, Thanks for pointing this out. I did not edit the information properly. I will have the proper info up in a few minutes.

    This concept is TOTALLY NEW to me. It is a MUST LEARN for me...for my own personal work and to make me a better teacher.

    A penumbral eclipse is the Moon passing through the penumbra of the Earth's shadow. This type of eclipse is not as deep/dark as a regular "umbral" eclipse. In fact, most people won't even notice a change in the moon's brightness.

    http://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2013Oct18N.pdf

    You have the additional problem that the moon will be in eclipse as it rises, so any dimming could also be attributable to atmospheric effects.

    So, the gist is, you probably won't get any deep eclipse shots, but you should get some nice shots of the rising full moon.

    Clear Skies!
