Here is one I took a while back with a 60D in the middle of night at Old Faithful.  It is likely a repost, but it brings back great memories of being all alone while Old Faithful went off.

I have been using a Gossamer Gear Mariposa backpack which is an older version of the newer http://gossamergear.com/packs/backpacks/mariposa-ultralight-backpack-all-bundle-dyneema.html that has a removable hip belt.  When bringing photography equipment, I replace the hip belt with a Think tank belt and attach my Think Tank holsters, lens bags and accessory bags as needed to the exposed side portions of the belt.  This gives me an ultralight backpack with the ability to add photo gear as needed and the camera and lenses are readily accessible in the side holsters.

I use the EdMika adaptor on a FD 800mm lens with my 5Diii and my 60D and I am very happy with the results.  I have had better luck on the full frame 5Diii, but this may be due to having more experience with the lens by the time I bought the 5Diii :

These were taken one cloudy morning on a canoe trip below Squaretop Mountain in the Wind River Range of Wyoming between the two Green River Lakes.

I took these using the Tamron 150-600mm at the MotoGP in Austin.  It was the first time I used the lens for such fast action.  When I tried to pan, I didn't have much luck.  However, this may have been due to having the IS on when attempting to do so.  Many of the shots I took using the Tamron at the races can be found at http://www.pbase.com/lebthree/2014_motogp_austin&page=all  I will let you judge the sharpness of these.  Admittedly, the last two shots are a bit soft, but most prefer the subject that way.

Dear friends.
Thousand thanks for all GREAT PHOTOS of the RED MOON.  Sorry. Past two nights were  Thunderstorm and raining night for my home town( Apex, NC., USA.)---No Red Moon in the cloudy sky.
Well, Here are my RED MOON by Post processing/ Photoshop----Ha, Ha, Ha.

I hate it when people try to pass off a photoshop image as an original.  Again Surapon, you don’t fool me.  I found the original photograph that you lifted this image from on the Daily Planet website and posted it below.  It shows not the red moon, but you returning from your home world.  I will not let you keep up this deception through some clever cropping of a lifted photo.  This has to stop.

I was taking the photos on fairly solid, but a little wet, ground.  I had two tripods set up.  One was for the 800mm fd lens and the other was for the Tamron.  Unfortunately, the head I was using for the 800mm was unable to solidly hold the lens at the high angle I needed when the moon was in the full eclipse position.  Therefore, I used only the 150-600 for the red moon shots.  The tripod I used for the Tamron was not as solid as the one for the 800, but I don't think that camera shake was the issue.  I used a remote trigger (the CamRanger) so no vibration from that and was using live view. There was no real wind out at the time.

I have done several star photos before with other lenses (including the 800, a Canon 70-200 2.8 and a variety of wide angle lenses) and have not had had the stars come out in such a squiggly pattern before.  Blurred yes, but consistently squiggly like this no.  I first attributed the moon blur to the duration of the shutter, the length of the lens and the movement of the moon.  However, that does not explain the squiggly stars.  I need to go out again and try some star photos with the better tripod and with VC (IS) on and off to see if I can repeat the effect.

Thanks for help in brain storming this issue.

Kindest Regards, Lloyd

Here are a few photos from the 2014 MotoGP races in Austin at the Circuit of the Americas.  The rest can be found at http://www.pbase.com/lebthree/2014_motogp_austin Some of the photos are easier on the eyes than others.

Thanks for the confirmation that it is likely the IS.  And dcm, thanks for the link to the Tamron manual.  I always wondered why they included these manuals with products. 

And jrista with regard to the composites, now you are just showing off.  Good work.

Kindest Regards, Lloyd

The bad.  Let me know what you think is the cause of this.  It only occurred on the 5diii with the Tamron 150-600.  I don't think the tripod moved this much and I don't think it is from the shutter, but it could be.  Most all of the Tamron ones exhibited this shake when I was taking longer exposures.  The first one is really odd as it duplicated the shaken star all over the frame. The first was a 20 sec exposure and the 2nd was a 3.2 sec exposure.  I had the Tamron version of IS on. I was also using the CamRanger to activate the shutter.  Any thoughts?

Equatorial mounts are a lot easier to use than that. They sound very technical, but they are actually simple and elegant devices. All you would really need to do is use the hand controller, set it to lunar time tracking (vs. sidereal, which is the default used for stars), pick the moon to point, center (there is always a bit of pointing error), and start imaging. Once you set it, you can pretty much forget it. The only extra bit of work is the meridian flip...once the moon passes the meridian (from east to west crossing the imaginary "12 o'clock line" overhead), you need to tell the mount to goto the moon again, and it will flip the mount to the inverse orientation...then you can image for the rest of the night.

Jrista, you have failed to convince me that an attempt by me to mount the equator would in any way be seen as elegant.  Plus, I live in Texas and such an act is probably illegal.  I am also concerned that if I tried one of those meridian flips, I would end up in the hospital.  Take care, thanks for the tips and keep posting those great photos.

Some great shots by Jrista and Slyham.

I have not had time to fully sort through the photos I took last night with my 800mm and the 150-600, but most of the ones taken during the full eclipse had too much motion blur.  As the moon got darker, I just increased exposure time.  This was a mistake.  The moon moves rather quickly across the sky and the longer exposure introduced blur.  On the small screen of the camera they looked deceptively okay, but when I downloaded them to the computer you could tell the moon had moved a good bit even during a one second exposure.

I just now did a little research on the issue and saw a web site which recommended that for lunar photography you should take 250 and divide it by the mm of your lens to get the maximum exposure time to avoid blur.  See http://www.amlunsoc.org/photography.htm   For my 800mm lens, that would be no more than a 30th of a second and about a 40th of a second for the 600mm.  (this seems to be similar to the 500 or 600 rule applied to star photography) Or I could do it right like jrista and get an equatorial tracking mount.  Unfortunately, I would also need Mr. Spock to help me operate it.

It is a good thing there may be a few more of these events coming up.  Time to crank up the ISO and open up the lens if I am going to use the long lenses to photo the next one.
