cls ccd filter

[Stephen Greenfield]

Hi ,

having just modded my 1000d and removed the filter , and eventually getting it to work again (dam those ribbons :-) )

should I now invest in the Astronomik CLS CCD filter? I had bought a Hoya Red intensifier filter for widefield work for the lens and have a light pollution filter for the telescope eyepieces , will i notice a big difference if I invest in the astronomik? Does it affect the camera for anything else apart from the Ef-s lens ? The cheapest I could find in the uk was £108 , anyone know of cheaper ?

Thanks

How many of the filters did you remove?

If it was only the rear one then you could get away with the normal CLS ...

Hi Stephen

I've got a modded 1000d and a CLS CCD filter and I'm very pleased with it.

The combination gives a slightly blueish tinge (easily corrected with curves in Photoshop) but dramatically cuts down light pollution.

Hope this helps

Thats great. I know you get more of a red tinge , and certainly there was evidence I used too wide an aperture but I do think the light pollution was playing a huge part in 'redding out' the image.

Anyone know of a price cheaper than £108

Ok stupid question time , whats the difference between the eos cls ccd filter and the cls filter and which do i need :-(

The CCD version has an inbuilt IR filter, it is the one I use on my modded 1000D as I did not replace the canon IR filter only removed it.

For some reason I tend not to get the colour caste, whether this is due to the fact I use a fair few flats when stacking I don't know, I use sky flats BTW.

So for my modded 1000d , where i removed the IR filter i would be best off with the following ?

Astronomik CLS-CCD for Cameras with IR Filter Removed - Canon EOS Clip

explains why you may not need extra IR blocking if you use one of the mentioned Canon cameras.

PS: I bought the non-CCD CLS clip filter but I haven't used it much yet.

A very interesting point, well it just so happens that I also have the plain CLS filter as well, given some clear skies I will try and do a back to back test to see if there is any difference.
