Astronomik eos clip in filter - which one?

[rustigsmed]

Hi,

I have a reflecting telescope and a canon dslr. I modified the canon to full spectrum recently which has resulted in good deep space results. However when I photograph the planets I use a powermate or a powermate and Barlow.

As I've introduced a refractive element it affects the image. I believe to counteract this I need a filter with an IR cut off.

Does anyone know which is best to use in this circumstance?

It looks like the L filter and the OWB filter will do the trick?

I assume the cls ccd won't be effective for planetary.

This I think it a processing issue and sky clarity. The RGB requires alignment and Registax has an auto or manual RGB layer adjustment I used to use a lot in the past.

Hi Malcolm
Thanks for the response.
The planet was originally 'pink' and I used the auto align rgb function in registax 6 (and also tried in astra image). Hmmm ...

Usually an Unmodded EOS already has an IR Filter so there is usually no need for a filter and some of the images I have taken are with EOS with no filter. Sometime I notice in poor seeing it is very hard to get good images.
