Just wonder... the live preview seems a big plus for focusing, just wonder how's the performance, like noise, etc.
Any early samples would be nice.

I picked up a Canon 450D (XSi)from Circuit City (10% off)to modify for astro use. Dark frame testing and a comparison to the Canon 300D has been posted here:

I can't see how the 'Live View' function could help with focusing as the frames would be too fast to pick up on faint starlight.
But I'm only guessing this is the case.

You need to try it. It has no problems focusing on stars of 3rd Mag or better. Many people here are having great success doing it, myself included.

Focusing with Liveview makes focusing no more than a one minute procedure using the built-in Canon software...it is fantastic (on my 40D).

How would the 450D compare with a 40D?
Do you have to use shutter control with the 40D or just the USB.

I just used the 450d for the first time last night with my C11 (have been using 300d for years):
1. awsome
2. live view is fantastic for focus and as-or-more accurate than my AFconfirm ring
3. tight stars across the field
4. HUGE image and exceptional resolution
5. used the EOS utility to control the whole process - one click for live view -> focus -> used timer for a sequence -> super speed on the download of the RAW files (3 secs?). This setup was actually superior to my use of DSLRFocus and the 300d - only caveat is that you have no FWHM indicator in the canon software (oh well)
6. battery life was amazing (i fully expected to see it drop using the live view after a while) - should be able to get a whole night with one battery (no more battery grip!!!)
7. nice and light (much better than the 300d)
8. ONE CABLE!!!!!...yes ONE....usb only, no need for the shutter release
9. CAVEAT - mirror lockup does not happen with the EOS utility, but I dont thing the shake registered any more that guiding and wind
10. NO amp glow at the sides!!!! - again, coming from the 300d that is a major bonus
Overall: absolutely fanstastic - need to play with settings for light enhancement etc to make sure that items used in daylight photos dont interfere with staro work.
Need to get under dark skies for a real test with colour and saturation, but it is already far superior than my 300d even with some dinky 4 minute shots (just tests on M51) and a 7 minute on M3.
Will post photos when I get a chance
Cheers

This is very basic but interesting none the less:
http://www.dpnotes.com/canon-40d-vs-canon-450d-digital-rebel-xsi/
When I was researching my decision (I took the liberty of adding the camera to my sig though it won't arrive till the 17th  ), I recall reading something about the 40D also having an advantage with either chip size, pixel size, noise, or a combination of those. A quick search failed to locate that info and I'm running late for work.
Based on what I found, the 450D should be an excellent AP camera, just not quite as good overall as the 40D. For the price, the 450D seems to be a bargain. Since my camera will also be used for daytime use, I bit the bullet and went for the extra features of the 40D.
From what I understand, the USB and included Canon utilities does it all...you are are not limited to 30 sec exposures in bulb mode when connected to a laptop.
If I find that other info, I'll link it after work.

Well, I still can’t find the source of the information I used for deciding on the 40D over the 450D, but as I recall, the following was the jist of it, and the main reason I chose the 40D for AP, beyond my desire to have a more full-featured daytime camera.
Two quotes from this site…
http://photography-on-the.net/forum/showthread.php?t=475861&page=4
Quote….
“I looked up the sensor size for the 400D, 450D and the 40D...they are all the same size 22.2 x 14.8 mm
jamming more pixels into the same size sensor ie; 12mg.. makes the pixels smaller and less sensitive to light....they did the same thing with the Canon S UZ series cameras...the S2, S3 and S5 all had the same size sensor with each model having 4/6 and 8 mb with the S2 having the best picture of all three of them”.
And….
“the 30D sensor size is 22.5 x 15.0mm Digic II
the 40D sensor size is 22.2 x 14.8mm Digic III
plus more pixels in the same space become smaller which adds to noise which adds to picture quality”.
I admit I have no clue and have based my personal decision on what others have written. That said, the 450D has nice features at an extremely nice price!
Hope that helped answer the comparison question…back to discussing the 450D.

I had a clear night on Sunday and even though the skies were lit by the Moon at 75% phase, I did some imaging with the 450D and an Orion ED80. Lunar and Deep Sky images along with my initial thoughts on the camera which I will be modifying for deep sky have been posted here:

Gary,
Very nice photos!! I particularly like the first moon shot...looks like you're looking out the window on the way to a lunar landing. Nice detail on the galaxy to the lower left of M13. Very impressive (to me anyway).
My camera arrives tomorrow and forecast is clear. Looks like I will get my first shot at AP, though it will have to be unguided

What about long exposure? you still need another cable for this? or with the software of the canon you can already put more than 30 sec?? (i have the 400D and it only gives 30 sec) ???

Hey Alex DJ
Long exposures - one cable - and al with the software that comes with the camera - no need for 3rd party suff - I did a run of 4 minute shots and a couple of 7 minutes using EOS utility (see note above) - cruddy skies and my tracking was a little off but the star spread and pixelation are great -> nice small stars and small pixels for smooth roundness - I have already decided to sell off my 300d after one night of playing with 450d.....to give a good opinion on noise levels, I need a night of clear during new moon (been hazy with 1/4 + mooon since I got the camera - light gradients galore)
More as I get it...cheers J

Dragon Man,
I had a chance to play with the Live View feature and found that focusing on stars was quite easy. Sometimes stars in the standard Live View display were barely visible but when I switched to zoom mode, they became brighter and easier to focus on. I posted some screen shots of the Remote Capture and Live View (450D) camera functions here:

Hi!
I'm about to pick up a 450D myself. I don't intend to control it via pc - I prefer to use a remote shutter release. Let me get this straight, I won't get more than 30sec bulb exposure with this setup??? I'll need a laptop to get longer exposure???

Joel,
No, you won't need a computer to do long bulb exposures. I tried the Canon remote switch RS-80N3 that I use with the 10D and 300D for long bulb exposures and it works also for the 450D.

Gary,
That's a relief because I just sold my Nikon D40 to get the Canon 450D! Now which Canon remote will allow me to preprogram a series of timed long exposures? I'm trying to do away with a laptop.

I wonder how is its H-alpha sensitivity? Actually, it's the low pass filter passband.

Hello,
1- You need to find a fairly bright star
2- Center it in the zoom window
3- Play with your focusing, be it by hand focus or mechanical focus motor.
4- Then I still put my difraction mask on the scope.
5- take a 10-15 sec exposure at 1600 iso.
6- Look for those big long and narrow difraction spikes.
7- Tweak the focus a little in and out, until you find the best focus.
This whole procedure can take less than 5 minutes. Don't rush, take your time, critical focus is the difference between a good picture and a great picture. Have you ever seen the difference between a FWHM 2 and a FWHM 5. I remember seeing a video on focusing, the difference is amazing. bottom line get the live focus, it will eliminate some wasted time. It can also help you collimate your scope. It will also help you center bright stars for calibration, the finderscope is almost not needed. I hope this helps,  Andy

Hi,
I just got my Canon 450D and discover some issue with the 14-bit CR2 RAW image when open using both my astro image processing software (AIP4Win V2.2.0 & IRIS 5.53):
1) There is a black border at the left and top of the image.
2) There are bands of distorted colour around the edge of the image.
3) Both AIP4WIN and IRIS report resolution of 4312 x 2876 instead of the Canon specification of 4272 x 2848.
Anyone had the above issue and do you think it'll affect the operation of the image processing?? Any sugesstion??
Thanks and have a nice day.

Until updates are available for those programs to handle the 450D RAW files, you could use Canon's Digital Photo Professional to batch covert the RAW files to TIF files that the programs will recognize. I use an older version of Images Plus that doesn't support the new RAW files and that is what I have been doing.

Hi,
But the problem is that calibration had to be done in bayer array format.
Anyway, I do a test on AIP4WIN and IRIS again, but this time I took an slightly overexpose the image. I found that although the IRIS got the black border and bands of distorted colour around the edge of the image, the data seem to be correct and the details are preserve even in the brighter area. But the AIP4WIN clip the data at 12-bit (max. 4095) and all details in the brighter area are lost. 
Seem like I still can use IRIS to calibrate my image. Hope AIP4WIN can come out with an updated version to support Canon 450D soon.
Have a nice day.

On Monday night I took first deep sky images with the modified Canon 450D. Targets were M51, M13 and the Virgo Galaxies Core with a new Astro Tech 127mm ED Apo Triplet. Was not able to get the imaging time I wanted for the Virgo Core. Skies here are pretty light polluted so am anxious to get the camera under dark skies. No amp glow on this camera, noise was not an issue in cold temps and the live view focusing was a pleasure to use for framing and focusing. Images posted here:

Will be using the Canon remote software tonite.
Thanks to Costco's 90 day return policy I am able to return my XTi without a problem.

I'm thinking of going with the 450D over the 40D because of the 450D's lighter weight. However, I'm concerned about the size of the files generated by a 12MP camera and whether my laptop can handle the files for processing. Its an HP nc6220 with a Centrino 1.73ghz chip and 1 meg of ram. Any thoughts or experience with the issue? Thanks.

Mike,
I had the same concern. Using an older version of Images Plus (Version 1.72) I was able to do my usual workflow process without problem, except my version of Images Plus can not convert the RAWs to TIFs, so I used Canon's DDP for that. My notebook is a Pentium 4 processor - 2.8 GHz - one meg ram.
I don't know what stacking softear you use, but tonight I tried the free software Deep Sky Stacker Version 3.2.1 because it can work directly with the 450D Raw files. After a few clicks I had a median combined image automatically calibtrated with darks and flats all having been opened in the 450D CR2 file format. The resulting median stack was better than the median stack I got with Images Plus, in shorter time and I will be updating my site with the improved 450D deep sky images.
I think you will hardly notice any increase in processing time between the increased Megapixel size from 10 Megapixel (40D) to 12 Megapixel (450D), but that is just an opinion.

After a bit of a learning curve tonite, I was able to finally focus to my heart's content! I got a few good pics in terrible conditions. Not enough time to do multiple shots to stack, but I got a good M13 shot, a dim but passable shot of the Spindle Galaxy, and a few good pics of Saturn. I tried for M51, but it was too dim for the bad light pollution.
Only problem is now that I need to re-allign my scope, the GOTO, is just a squidge off.
All in all, I am impressed with this camera, the noise levels were much lower than the XTi at 1600ISO and 800ISO, and I was shooting on a fairly warm Phoenix night.

Thanks for the info Gary on the 450D and laptops. I too have been a long-time user of ImagesPlus, but now only use it for image acquisition/focusing and for its very good DDP function. Won't even need it for acquisition/focusing if I replace the XT with a 450D or 40D. I agree with you about the merits of Deep Sky Stacker. Last summer, I switched over to DSS for stacking because of its ease of use and excellent results.

Mike,
If I would have known how much better stacked images are with DeepSkyStacker, I would have been using it for many months. I may have to go back in time and restack some images; it would be simple to do with just a few clicks. I updated my first modified 450D image web page with the improved images (hit refresh):

I couldn't get Deep Sky Stacker to work. On the laptop I got out of memory errors (It has 2 gigs on it) and on the home pc, it flat out doesn't even start..I get errors.
Gonna have to figure this out

Criterion, I am surprised by this. By far DSS has been the least painful free astronomical software. In fact, this is in the category of "pleasure to use"! Maybe you could post your query in the DSS Yahoo group, and see what may be happening.

My home pc is odd, it has issues.
But the laptop is a puzzler, I load in 5 pics, and hit the register and stack, and after a few minutes, I get an out of memory error.
I'll read the manual.

Did you by any chance have the "enable 2x drizzle" or "enable 3x drizzle" checked? If you did the files become huge and so does the memory needed.

Yes, EF lenses will work fine with your XSi.

I turned off the 2x drizzle and had the memory. DSS ran. Question: I stacked 5 pics, but afterwards, the header still said it was one 2 minute exposure, rather than 5 exposures equal to 10 minutes. So I used the DSS Live! and got a stacked picture.
As for my home PC, still no go, I'll have to send the error to the author for help.
A few books for the 450/XSi are coming out soon, check Amazon
