Prepping for the eclipse. In a perfect world I would like to be able to set the camera to take a 7-shot bracketed series continuously without me fussing with it during the two minutes of totality (I'd like to actually watch it). I'm trying to find remotes or apps that could program such a thing but am surprisingly having trouble. I was curious if anybody was aware of something that would carry this out for me?

If you have an Android phone or tablet, you may be in luck: "DSLR Controller" may have that capability,

Seems to me you could set it for "time lapse" of, say, every 2 seconds and do AEB bracketing on each triggering.

Interval timer shooting can also be combined with AEB, WB bracketing, multiple exposures, and HDR mode.

That 5DMkIV "built-in" intervalometer combined with HDR mode should work to accomplish what you want. I haven't tried this, but it might work.

These are good thoughts. The annoying part is as far as I can see Canon still has a 3 exposure limit for HDR bracketing. I think I know how to do HDR (3 exposures) and how to do multiple exposures (same exposure setting) but don't quite know how to do both together to run through say 7 shots at 2/3rd stop intervals.

I may send an email to the app creators Bear, but I suspect they are just going to control the in-camera settings which is, as far as I can tell, limited to 3 exposures on HDR.

I found it! There is a setting under custom function 1 "number of bracketed shots". I swear I searched all the settings a dozen times. Apparently I was, as my wife says, "looking like a man"...

My thought is rather than figure out and then collect the three appropriate exposures to blend (which may take half the total time of totality), I would shoot over a -3 to +3 range and then later select what is necessary.

hahn, are you planning on shooting? I know it doesn't go right over Colorado, but it isn't too far away. I suspect you'd have to travel a bit Robert...

Yes, I plan to drive to Casper, WY to be in the totality path. 4 h 3 min (263.1 mi) via I-25 N. It's a day trip from here. All hospitality accommodations have been reserved, so it may be an event to remember.

I am thinking to go to Lake Murray Dam Public Park in SC. The place is about 9 hours from house but I know some one over there to probably can stay over night on 20th and then drive to the path.

This is what I will be seeing when i will be at Lake Murray Dam Public Park in SC.

No, I'll be missing the event :-(

But they specify TWO different things; works with AEB (you know you can bracket a bunch that way) and with HDR. Remember, Canon's HDR function delivers you a merged HDR out-of-camera, not the bracketed series.

^^ THAT!
You just want straight exposure bracketing, not the HDR-specific feature.
I'm also going to be in the West, will be keeping my options open as far as locations until a couple days before, and following the clear weather predictions the day before. I probably will wind up in either Idaho or Oregon. For sunshine, Oregon is looking like the smart bet. I know that at least one other DPCer, 31.gif strangeghost, will be out that way.

I'm in the process of assembling equipment (literally building some solar filters) and will be testing those in the next week or so. Also will be testing tracking and exposure at that time. I'll have two cameras working, the 5D IV and the 6D.

I'm trying to decide between going to Madras, OR and camping in someone's field or just driving 40 minutes north from my house and finding a place to set up shop. The traffic predictions rival the apocalypse so I'd rather be in place the night before. Still trying to figure it out.

As far as equipment, I'm going to buy a tracking mount this week. That will help with not having to worry so much about things during totality. Maybe a bit overkill since I'm only going to be shooting 400mm, but I have wanted one for wide field astrophotography anyway.

If you wind up in Oregon Fritz, drop me a line.

Will do, and I almost certainly will be coming through. After the eclipse, I plan on hitting Crater Lake :-)

Which mount are you looking at?

I have a friend who does a fair amount of astrophotography and he potentially turned me on to this one

That oughta do it!
One thing to consider is how to get even a crude alignment in daylight (without having reference to Polaris). If yoiu are in position the night before, then no problema, align at night. If you are aligning in daylight things become, shall we say, more interesting. Don't know if I will be able to set up the night before, so daylight alignment might be necessary. I'm planning on working on this at home, crude alignment goes something like this:
- Set up tripod and level using bubble level
- Mount tracker and adjust the wedge to the (known) longitude. That gets elevation within a degree or two
- Adjust pointing direction of axis on tracker to point to (known) offset of Polaris from magnetic north. This has perhaps the larger error, potentially several degrees

The above is a first cut and will probably get me close enough that any residual motion will not be a concern. Again, I will test at home and refine technique prior to departure.

I will be in Oregon for the eclipse. My son is going to choose the spot, but I will be in Portland for the week. I've never been there and am excited to explore the area.

You're gonna have a blast. It's a great (and quirky) big town. Be SURE to take a day trip up the Columbia River Gorge, either a road trip or, better yet, a day boat.

The reality is our mounts may be overkill. At least for me. 400mm has the sun and corona taking up maybe 1/2 the full frame. Shutter speeds, I'm guessing will be around 1/10th of a second on the slow end. I suppose it would be good to help with stacking shots if that might be helpful.

I saw an absolutely gorgeous shot of the corona and now I am questing to duplicate it. It even has earthshine on the moon. Gah!

Corona

Elaine, you will have fun. So many waterfalls to see up the Gorge. Be sure to go!

They may in fact be overkill for the eclipse... but I've already enjoyed a taste of what I can do in a truly dark sky site, and itching to do some more of it. Hoping I hit some good-weather nights in scenic areas on this trip.

Thanks for the suggestion!
