Camera Problem

[Russell.D71]

:hello2:Could anyone tell me what they mean by canon camera modified/unmodified?

Basically the camera as you buy it has a filter that cuts off wavelengths that would be useful for astrophotography but which are not needed for 'normal' day to day photography.

A modifed camera has had the filter removed or at least replaced with something more appropriate for astrophotography.

Hi, Modified means that the internal infra-red filter has been removed.

If you are a DIY sort of guy, the modification is explained in a guide here. You must take care though, if the camera has been bought new, the warranty will become void once you open it up.

"No" not a DIY guy where camera's are concerned but thanks Ron. The camera will best be left as it is unless l get brave!

Welcome to SGL Russell, it's not an absolute necessity to get a DSLR modified for astro use as there are quite a few targets you can pick that will be ok. The newer Canon models seem to be more sensitive to the Ha light frequency than the older models like the 300/350D.

Hi Russell. You can definitely get excellent results without modifying the camera. I would suggest you get the hang of imaging first, then consider modding it later. My camera is unmodded, mainly as I use it for terrestrial stuff too, and can't justify the expense of two cameras.

Hello Russell, a very warm welcome to SGL, have a look at "Astronomiser" their web site will give you an insight into camera conversion and what can be achieved, enjoy the forum.

What colour is the extra infrared light displayed in an image obtained with a modified camera? Presumably it adds predominantly to the red channel? Does that give a red cast to an astro-image before it's tweaked?

Secondly, is light pollution more trouble for a modified camera?

Hi Russell, welcome to the Lounge.

Hi Russell and welcome to SGL

A lot of nebulas emit light in the red end of the spectrum, from the dust clouds around them. Have a look at pictures of the rossette nebula as a good example. The red colours in the dust clouds are considerably reduced in unmodified cameras.
