Astro Photography

Yes I will admit it I am a dummuy when it comes to cameras. I have a Canon EOS 400D and want to know the ins and outs of taking photos with it at night.

Tried this evening to use it on a tripod to take photos of saturn and they all turned out as a ball of light. Tried all the different settings nothing.

Any good sites tht explain it to a dummy

please help.

thanks

There are many much wiser souls than i on this forum but my understanding is that you remove the lens of the SLR and attach it to your focuser (via adaptor) and use the telescope as the lens. If that helps.

Hi Shane,

A bit more info is needed. If you were using say a 18 to 55 mm lens on the Canon then Saturn would appear as a star, it would be so small. To get any decent detail on Saturn people normally use maybe a telescope and barlows to get at least a 4000 mm focal length.

Without a scope and as long as your tripod is stable then your Canon will be great for widefield.

If you were using the Meade in your sig and the canon at prime focus then you would have got something but if all you got was a ball of light then your exposure was too long. I havnt done planetary for ages but if I remember correctly you only need a second or less. Start at around a second and go down until the image is not overexposed.

Try this for a start, basically though google astrophotography and away you go.

also when you are working with long focal lengths i.e: 4000mm + you need a very still clear night
