Will the cannon 400d take good pics?
What is the method of attaching this to my 114mm tasco luminova telescope?
Anyone with any help let me know,it would be appreciated.

The Canon 400D is very capable of taking Astrophotographs. I use one all the time. Some of my images are here >> http://southcelestialpole.org.au/blogs/astroman.php

Really must update it with some latest images, such as..

and...

http://southcelestialpole.org.au/for...ach=8342;image

and...

http://southcelestialpole.org.au/for...ach=8344;image


These were taken with various equipment from a 18,,055mm kit lens to an 8" f6 Newtonian.

What focuser does the Scope have? Does it have tracking ect... I know someone with an old Tasco from what I have seen of his it only had a .975" focuser which is inadequate for hooking uquipment ep to a DSLR. You also may find that you will not have enough in focus, so the Primary Mirror needs to be bought forward slightly... Some things to think about. Astrophotography is really enjoyable but without the right equipment can be very frustrating. Also it take alot of work to get many of the images you see around the place.

Go for the 350D. It's a lot cheaper and the same, or better than the 400D.

Ingo, he never stated that he was thinking of buying one, it was a general question if it could be done. "Will the cannon 400d take good pics?"

I think you can come to a conclusion that he's looking at buying one. Otherwise he could care less about how to attach it to his scope.

Without finding out from him, I wouldn't come to that conclusion at all, I know many people with cameras that are asking me how to attach them to a telescope. That doesn't mean they are looking at buying one...

Will await to see what he says.... But yes with the inclusion of the 400D and 40D into Canon's line up of cameras, the 350D is a cheaper option if you are looking for a good cheap DSLR for Astrophotography.

The Canon will take very good pics but its the photographer(you!) that will make it all happen. Go for it.

Ingo you keep saying the 350D is better than the 400D. What facts are you basing this on? Any personal experience?

I'm a 350D owner that would go for a 400D in a heartbeat if I could afford it.

It's from reviews & other professional photographers I've know for some time. All upgraded to the 400D and don't like it. It's a horrible sensor for one, you're paying for the low pass cleaning and it doesn't work. Why not buy a 350D with a more sensitive sensor that takes in more light with less noise? It's so much cheaper also. The only thing the 400D has on the 350D really is a bigger screen some small new settings.

Can you give me a link to the sensors in both the 350D and the 400D? I thought they were the same.

The 400D has an extra 2 MP. Nothing to sneeze at.

I don't know many/any professional photographers who use a 400D, or who would upgrade from a 350D. They're more likely to have the pro-series not the consumer ones.

Hi,

I'll go with a comparision by somebody that knows what he is doing, i.e reknown astronomer/astrophotographer Christian Buil at:

http://astrosurf.com/buil/400d/400d.htm

To save translating and reading through the graphs, it basically states that although the 400D sensor has smaller pixels, this is partly offset by better efficiency converting light (i.e the 400D has higher Quantum efficiency). The AA-IR Filter seems to stop a little more red light unfortunately. There is a little more dark noise (i.e long exposure noise) in the 400D but no electroluminence glow. Overall the 350D is the prefered camera for astrophotography, but the difference is fairly SMALL.

So Shane the 400D is still a very good choice and keep in mind you have a better camera body design in the 400D as well.

Terry

See...350D was better. What I said all along. The sensor is less sensitive to light on the 400D also.

lol I wouldn't be claiming that victory, Ingo. Terry's information is what I was after, not 3rd hand heresay from "professionals" who use a 350D.

And where does this statement come from?

For the very minor differences as stated by Terry, I'd still prefer the 400D (for me) because of the greater resolution.

As far as I can see and I apologise to Shane for hijacking his thread.. Is that the differences between the 350D and 400D are so small its hardly worth the debate it generates. Good on anyone who buys these Cameras, they are both great cameras and the people that know how to use them properly can produce wonderful results. I personally got my 400D for more than Astrophotography, if I could have afforded it at the time I would have gone the 5D, but this wasn't to be. I like the 2.5" screen for normal use, it gives you a big enough screen to see how your image turned out. There are some things that could be better, for night time use, but thats not exactly what this camera was designed for.
