This is a very interesting camera for Astro... the DIGIC 5 noise level seems to be unbelievably low. Does anyone know what the ?1:1 ISO? is for it?

The built in WI-FI goes further towards the dream of a telescope tether carrying only DC-POWER through it, one less USB connection, which means less traffic on any remaining USB connection, and less chance of a USB cable imparting any noise into the camera.

How does Canon handle the WI-FI? Once you establish the WI-FI link between the 6D and the Canon software, does it appear equivalently as a USB connected camera from the point of view of software like Maxim, or BackYardEOS? Does anything support the 6D for shooting?

I haven't had it under the sky yet, but the attached picture of my bench was taken by a wimpy closet light at freakin' ISO 8000 !!!!

No I wont mod the 6D... it will be my main camera. It does free up my T2i to be modified though.

Looks like Maxim cant control the 6D now. Probably nothing will work with it at this time eh.

Mike,

Canon has to release a new version of their communication library before the third party developers (like me ) can implement 6D support in their products...

So if I want to use it now, I can manually shoot darks, lights, flats no problem, but how would I subtract them before conversion in Canons software?

Yep... sadly.

It usually takes Canon 3 to 6 months to release their SDK after a new camera is released. I have verified last week and it is still not released. As soon as Canon releases it I'm sure developers like myself will rush to recompile our apps with the new SDK to support the 6D.

Mike, I'm not sure I understand your question.

You would take your lights and calibration frames just the same. Download all .cr2 from the camera card and use them as you would normally do with your stacking software.

If my stacking software cannot recognize 6D frames I mean. I could certainly take a bunch of light frames and do the color conversion in Canon DPP to TIFF, but is there any way to calibrate them pre-conversion.

Thx

Hi Mike -

I don't think your stacking software will care what camera captured the .CR2 images. CR2 is a standardized format, so the only thing unique to the 6D about it should be total pixel count and some exif info that identifies the 6D as the capture device. As such, I believe there's no reason you can't take all your lights, darks, flats, bias frames and throw them into your stacking software and come out with calibrated frames and a stacked image.

The issue for software developers is that Canon doesn't have the SDK kit that will provide them the interface to CONTROL the camera (at capture time in other words).

BTW, congrats on the new camera - can't wait to see your images from it!

Great ! I will try that, thanks. I did not know the image format was standardized. I was getting accustomed to software not being able to read anything every time I upgraded cameras.

It sure DOES!!!
Software WILL see a difference between the .CR2 of a 450D, and a .CR2 of a 5D Mark II/III, or 6D, 60D, 7D, T2i, etc, etc, etc...

Not sure WHY! so hopefully someone will chime in.

BUt I know for sure that this is the case. I have had way too many models that were not supported by DSS/Images Plus/Maxim/etc and had to wait for updates to the SW for the images to work in the SW!

YMMV, and this is all AFAIK!

Congrats on the new camera, Mike!!

the 6D's reviews are making me want to grab one as a backup to my D800! (wife would kill me for sure though..lol)

Cant wait to see some images!!

As long as you dont plan on imaging very faint Ha rich regions, the mod should never be an issue...
so galaxies, globs and open clusters, reflection neb, etc are all on the list!!

Oh wow...sorry..dreaming of images of M33/M45/M101/M81-82/M51/M83/a million NGC's, etc, etc with the 6D and TEC200!!!
OH man, doesnt the 6D have 1:1 Crop Video mode?? that means AMAZING planetary imaging with your TEC200 and this camera
(Probably need a barlow, I suggest ***THIS*** ,it will vignette on a FF sensor, but when in 1:1 crop mode, you will never notice!! oh, not to plug my own biz, but remember I am a Baader rep, so can always get you/any CNer GREAT discounts on ANYthing Baader/AlpineAstro carries!!!)

is there a way to subscribe to EVERY post you make, Mike?
I am going to be following your progress with high anxiety!
But no pressure

Clear skies!!

OK, I may stand corrected. According to Mike Unsold's description of IP 5.0 features, "All Canon CR2, CRW, and Nikon NEF DSLR raw formats along with Pentax, Olympus, Kodak, and Adobe DNG raw formats are supported". I'm assuming the 6D falls in the "all Canon CR2" category, but I can't speak from experience.

@Mike_Clemens - If you'd like to post a couple of lights and a dark or two from the 6D, I'd be happy to try a quick calibrate and stack in IP 5.0 so we can see if it works or not. Just shoot me a URL for the CR2 files.

I dont know...you may be right..
Hopefully someone who knows will chime in here

AFAIK, I know I have had to download the latest versions of DSS(for example) when I bought a 60D last year...it would NOT load/work the images at all until I installed the latest Beta version.
Same happened with Nebulousity...IIRC..
The only SW I have ever used that did work with any model was IRIS, and maybe PixInsight..

I could be wrong and my experiences were just coincidences

Adding another data point... It's common to need an updated version of Adobe Camera RAW to support CR2 files from new models.

Adobe and Apple have released new versions of their RAW converters in mid-December to support the 6D for Photoshop/Lightroom and iPhoto/Aperture respectively. The new versions are required. There are both calibration and pixel count differences between camera variations of .CR2 files.

Great camera!!!

Interesting feature, but it takes away sky time, and... only 1 dark frame? I have had really good luck shooting my darks at the end of a session and using 20 or 30+

I've been conducting some experiments with a 550D using the internal versus external darks with excellent results. Pairing a light with an immediate dark is a very powerful technique. It would be neat if you could pair the dark with the light taken immediately before and immediately after the dark was taken, however, a single dark several frames removed from the light would be of limited value. The biggest benefit is nearly perfect temperature matching between the dark and light. The BIG misconception about using internal darks is that the time taking them is wasted when it could have been spent taking a light. Keep in mind that the whole purpose of stacking images is to reduce noise and this method of taking and applying darks preserves the noise information that would have been taken if the frame had happend to be a light instead of a dark. So far my experiments suggest that the method of using internal darks becomes roughly equivalent to external darks after about 10 frames (10 light/dark pairs versus 10 lights and 16 external darks). I haven't taken a stand-alone dark in over a year.

Food for thought, but of course use whatever gives you acceptable results.

First off, every time I upgrade my Canon camera, I need to update the RAW Codec. So there is a difference in RAW files between cameras. Personally, I think Canon needs to address and improve this.

And a question...
Does live view work over the WiFi?

Interesting stuff. I can't imagine any better use for clear stable skies though than collecting photons from the target subject. My dark management has never gone perfectly and I get varying results. I think the in-camera darks would be more consistent but I would be unwilling to sacrifice the sky time.

That is interesting, but I'm curious as to how you are matching the temps of the darks and lights. When I began using the sensor temp, and not the ambient temp; my darks got much better at removing the noise.

You said temp matching is the most important thing. How do you control for improper temp matching?

And theoretically, why would a cameras internal dark calibration be any different then external once the temp is controlled?

Let me ask again...(without getting into the old debate/lecture of losing sky time)...where exactly is the setting to match one dark with multiple lights in the manuals of 5D (and 6D if it has that feature)? Has anyone tested that feature on 5D?

All I see in the 6D manual that sounds even remotely related is --

(when long exposure noise reduction is enabled) "the noise reduction process after the picture is taken may take the same amount of time as that for the exposure. During noise reduction, shooting is still possible as long as the maximum burst indicator in the viewfinder shows 1 or higher."

Does this mean the camera can work on the noise reduction for the previous frame while shooting the next light frame?

No not for CS3, "I think" the only thing you can do to get it into CS3 is with the digital negative converter?

NO, I was referring to a very different thing (plus burst mode may not be applicable to long exposures in AP, if I understand it correctly?).

Those with 5DMkIIs, can you folks confirm if there is such a thing as buffering up to five images in the camera and then taking a single dark frame to apply to all of 'em.

Unless there is residual image left in your darks, then each dark is a statistical sampling of the noise expected to be present at a particular temperature. It's random. If you apply only a single dark to a single image (or even multiple images) then you are doing nothing about address the variance of that noise (or the read noise from the dark).

I don't believe Adobe is updating CS3 with newer camera's RAW files. I had the same problem with CS3 not being able to read my Canon 60D CR2 files.

I've been using Digital Photo Professional to convert my RAW files to TIFF and then load them into Photoshop. The batch mode makes this fairly painless.

P.S.

Patrick; I was pretty busy last night with my T2i. I went through 4 batteries (I rotated 3 through my charger), 5 deepsky targets, and ended at about 4 this morning with the moon. I love how versatile this camera is and how Backyard EOS helps to pull it all together.

Now for a nap!

Just curious, would it be then beneficial to use the AC adapter in that case (I guess thermal noise would not pose a problem in the winter months)?

I would think so. I use an AC adapter.

When it's below 10F, I can only get 30m or so out of a battery. And every time you switch it, you risk bumping your imaging train and messing up and flat calibration.

I previously used an AC adpater with my XTi and I really liked not having to worry about the batteries. With my T2i I may end up getting one and if I do I'll spring for the Canon adapter. I have AC out at the scope so powering the adapter is no problem. However, to be honest since I image from home and control everything from inside my house swapping out the batteries has not been a problem. In warm weather they last about 3-1/2 hours, in the cold that sneaks down to 2-1/2 (so far), and I've heard as short as an hour when it gets really cold. I have run them completely empty before (one gave out on my last night as I was imaging the moon), but just to be safe I'll swap them about every 2 hours or between targets. It takes about an hour to recharge a fully drained battery, so I've never run out (yet).

I may go for the Canon DC adapter for the T2i. I've been using one on the 40D for years.

Wow! I'm speechless. And the new versions are more expensive than ever. Buy in now and assume they wont update it for future cameras. Sweet deal.

Is there a version of Adobe Camera Raw for Photoshop CS3 that will open images from 6D (or other modern bodies)? Or does Adobe try to force your hand on CS6 etc.





I don't believe Adobe is updating CS3 with newer camera's RAW files. I had the same problem with CS3 not being able to read my Canon 60D CR2 files.

Yep
I was fortunate to use my previous license number to just buy the upgrade rather than the full version, but still pricey. Me thinks Adobe likes its customers to support the shareholders but I guess that keeps them in business and make better products in the long run.

Does this mean the camera can work on the noise reduction for the previous frame while shooting the next light frame?




NO, I was referring to a very different thing (plus burst mode may not be applicable to long exposures in AP, if I understand it correctly?).

Those with 5DMkIIs, can you folks confirm if there is such a thing as buffering up to five images in the camera and then taking a single dark frame to apply to all of 'em.




No. I dont know where this came from, but I found nothing in my 5DII's manual regarding this...sorry.
This is EVERYTHING in the manual on ICNR..

Thanks Brent; I didn't find it either after all the looking around. Not sure why the author of S&T article would mention such a thing? Strange. Thx

I've been using Digital Photo Professional to convert my RAW files to TIFF and then load them into Photoshop. The batch mode makes this fairly painless.




Yes...that's my work around too. DPP does a good job.

Patrick; I was pretty busy last night with my T2i. I went through 4 batteries (I rotated 3 through my charger), 5 deepsky targets, and ended at about 4 this morning with the moon. I love how versatile this camera is and how Backyard EOS helps to pull it all together.





It was a really nice clear night Friday, and I thought there was a chance you'd take advantage of it. I was out for a little while observing, but don't have all the bits and pieces yet to use the EdgeHD to image with. In typical Ohio fashion, last night was cloudy again, now that my T-adapter and mounting bracket arrived.

overcast here... I at least hooked up the 6D to the TEC200 refractor today and saw that it worked. Tried to do an HDR pic in cam but too much wind to keep a tree in the same place.

This tree appeared jet black in DPP at ISO1600, this is lots of Photoshop levels to pull the colors and details out of the left side of the histogram. Data seems much cleaner than my T2i and light years past the EOS 40D.

As far as I understand it, if you set long exposure noise reduction to "on" (setting 2) with your Canon 5D Mark II, you can take several long exposures in a row and the noise reduction is applied at the end of that series of long exposures:

After the first long exposure, take the next right away, and so on. If the break between the long exposures is short enough (1-3 seconds or so), the long exposure noise reduction won't be applied until you stop taking long exposures.

Then, if you give the camera a longer break, the noise reduction will be applied to all previously taken images. I think you can even take 10 long exposures in a row.

I have bought a Canon 5D Mark II a few days ago and haven't had a chance to test it through a telescope, but on my balcony it seemed to work. I took three one minute exposures with short breaks between them and the noise reduction didn't start until I gave the camera a longer break. I have yet to measure how much time is needed for the internal dark frame subtraction after e.g. five different three minute exposures. It appears, the camera needs more than three minutes to do that.

Finally got some (briefly) clear skies and royally screwed up by leaving noise reduction on in the 6D. Here are 5 frames anyway at 5 mins each.

The workflow is horrific. I need all my familiar tools to allow me to select 6D !!!!!! I am mangling my already-noise-reduced-mangled data even further.

I can't even fathom what DSS spit out from it. In the end I used DPP to spit out TIF's which looked processed... I expect nearly black frames but DPP wasn't putting that out.

I need my Maxim...

Decent looking result from 'unmodified' 6D; for comparison, my only 25min integration here.... Thx

Thanks guys. One thing I will say.. coming from the APS-C sensor... this field is HUGE.

Here is a massive scale down of a single image to show the field from the TEC200/9 on a 35mm size sensor:

Field is big enough that extra galaxies are creeping in, that I've never seen on NGC891 shots before. This one from the lower right, presented 1:1 scale from a single frame. It has a tiny little dust lane. Maybe it's like a micro-m65.

Having all of that real estate is wonderful, right??

People think that it is pointless to go full frame just because their scope may not be able to fully illuminate, or provide a perfectly flat field all the way to the edges of the massive chips...but, hands down, you will always end up with a better CROPPED image from a FF camera, than an UNcropped image from an APS-C camera(at least with the current models available...)

Mike, do you have an image of 891 taken with the 40D also??
Would be interesting to compare directly..

Yah http://www.pbase.com/mclemens1969/image/117729846/original

Much more favorable conditions AND SOFTWARE !!!!

~SO~ can't wait to go after M101 with a full frame.

That is still very impressive!
If the 40D was able to do that, this 6D should be downright scary good once you get favorable conditions and your software!!
