Northern Pintail making a final course change prior to landing.

Beautiful shot of a good looking bird.

Here is a good example of a "reach limited situation" its not as sharp as I would like but the bird was halfway across the Wisconsin river so seeing conditions are an issue. Its a 100% crop with the 7dii and the 600ii. A higher res sensor or a tc may have given better results on this shot but a tc on that setup is a bit much for bif. I really like how gritty the bird looks with one inner eyelid closed.

Post Processing / Re: How to effectively prune your wildlife shots?

Dpp is pretty good for sorting and deleting. I just use it for that and find ver 3 to be much quicker than ver 4. It opens fast, use quick check, there is no lag between images. One finger on the arrow key one on the x (reject). Make one pass to x out the ones that look bad in normal view but don't get rid of clipped wing images etc. They may look good with a tight crop. Select reject images/delete. Make another pass at 50%, x out and delete the unsharp ones. Make.a third pass and try to pick out the ones you really like and star them by hitting #1 or #2 and delete the ones that are almost identical or close. You can whittle down 500-600 shots to 10 or 12 in about 15 minutes. I never go back and use those almost as good shots for anything.

Landscape / Re: Deep Sky Astrophotography

Astronomy has been a interest of mine since I was 10 years old. Now, some 30 years later, an Astrotrac (tripod mounted star tracker (non-guided)), a DSLR and a few lenses have given me a chance of actually taking photos of the objects I saw in astronomy books, magazines, etc - and I am really stoked! Here's a few astro shots taken recently:

The Great Orion Nebula (M42 + M43 + Running Man)
Full spectrum modded 6D + 70-200 f2.8L II lens with x2 TC @ 400mm. Tracked using an Astrotrac.
4x120s, 8x60s, 4x20s, 4x8s and 4x3s at f5.6 on ISO3200. Dark frame subtraction on the 120s and 60s shots.
Aligned with PT Gui and processed with Fitswork.

Lagoon Nebula and the Trifid Nebula
Full spectrum modded 6D + 70-200 f2.8L II lens with x2 TC @ 400mm. Tracked using an Astrotrac.
4x120s, 4x30s, 4x8s at ISO800 + 10x120s at ISO3200. All at f5.6. Dark frame subtraction on the 120s shots.
Aligned with PT Gui and processed with Fitswork.

Eta Carina
Full spectrum modded Canon 6D, 200mm, ISO3200, 4x120s, 4x30s, 4x8s and 4x3s. AstroTrac. Hutech LPS-D1 lens mounted filter

Eta Carina - Wide field
Full spectrum modded Canon 6D, 200mm, ISO3200, 4x120s, 4x30s, 4x8s and 4x3s. AstroTrac. Astronomic CLS-CCD XL-Clip filter

Comet Lovejoy (C/2014 Q2)
Canon 6D
70-200 f2.8L II + 2x TC @ 400mm, f5.6
20x120s exposures at ISO3200
Astrotrac used for tracking the stars

Heart of the Milky Way Widefield
Mosaic using a Sigma 35mm @ f2.2 on a full spectrum Canon 6D. An Astronomic 'L' clip in filter was used. Astrotrac used for tracking.

Hope you enjoy.

great images, jrista recommended that mount so that is what i am thinking of getting. they make what's called the "travel system" it seems to be everything i would need to get started except for a dovetail adaptor.

judging from your images i would expect you also recommend it.

would you suggest getting the whole "travel system" or just specific components?

Lenses / Re: Canon EF 11-24mm f/4L Accepts Rear Gelatin Filter
« on: February 27, 2015, 05:01:38 PM »
the trusty 15mm fisheye also has that feature but i have never used it. maybe there is some light pollution filter for astrophotography that would be useful?

I don't know if this article spured this thread or not.

that is a wildlife sanctuary not a game farm so the bears are wild but acclimated to humans.

I think Neuro mentioned hanging his 600/4 on a BR strap.

Here's what I've thought about getting for this type of situation (but haven't bought, yet):
http://www.kirkphoto.com/Kirk_Security_Strap.html

I have Blackrapid straps as well as the Kirk security strap.  The Kirk strap works well if the lens is the only thing you're carrying.  Frequently, I am carrying the lens and wearing a backpack, and that does not allow the Kirk strap freedom to slide, meaning you cannot just raise the camera to your eye.  I think the design intent of the Kirk strap was to carry a second large lens for swapping. 

I usually use a Blackrapid Sport-L with the 600 II.  When they came out with a left-handed strap, I didn't really get the point (except to make Ned Flanders happy), since you need your right hand on the camera to press the shutter button.  However, a left-handed strap is perfect for use with a supertele, since I lift it and continue supporting it with my left hand while using my right hand to control the camera.


i wouldn't trust an arca swiss clamp in that application.

What are you going to do, get some boat anchor chain and weld it directly to the lens?   ;)  The standard Arca-Swiss clamps (RRS, Kirk, etc.) can hold far more weight than a supertele lens.

i don't think boat anchors and welding are necessary. just screw the br strap into the threaded hole in the foot. arca swiss clamps can hold a lot but they can loosen and slip, i have had it happen. i would not trust an arca swiss clamp for a lens hanging upside down from the foot where it could slip out.

8k video is the exciting thing for still shooters I think. That's 33mpx stills at 30fps.

No it isn't, 8k video has a rendered output (essentially jpeg) of 6GB's per second, therefore filling up an $800 CFast card in just over 20 seconds.

Thinking of it as a video stream it's excessive and major storage problems for sure. The 7dii takes 20mpx shots and about 1500 raws fit on a 64gb card so with 30mpx shots you should get about 1000? If you set the frame rate to say 15fps and shoot short bursts then it would be useful to a bif shooter. The cost of the storage cards is a problem. If it gets to be a widely used format then that cost will drop. I remember when a 512mb cf card was $100

If you are going to be wearing a backpack then you want the br backpack strap. It has the functionality of the regular br strap but it attaches to your d rings. Attach it to the tripod foot and you are all set.

I read through the article and watched the video which is about 20 minutes. I have to give credit for figuring out and explaining this technique, it is sound but cumbersome and not suited for a scene with motion. If you are willing to spend the time shooting multiple images and processing then this is a good method but for me a high resolution sensor is a better way to capture high resolution images.
