Filter choice / confusion for full spectrum Canon 6D

[stevebb]

Hi,
I am about to take delivery of a full spectrum modified Canon 6D and know it will require a UV/IR cut filter.

I had considered the XL size clip filter but think I will go with the 2" screw in filter instead but I am stuck between 3 filters at varying prices !

IDAS LPS D1
Altair Astro Premium CLS-CCD UV/IR
Astronomik CLS-CCD

I will be imaging both emission nebulas and galaxies and because of the latter I have ruled out both Duo and Tri band filters. I will probably save up for a set of narrowband filters at a later stage ... once the bruises have healed over after the "bank of wife" found out I require a filter in addition !

The cheaper Altair Astro (half the cost) immediately springs to mind but I do not know if this works with a full spectrum modified DSLR (full frame). I do want to avoid vignetting if possible.

Many thanks in advance,

Steve

Which filter did you decide on? I’m thinking about those exact filters too.. more so between the  d1 and the altair cls-ccd.. curious to know your experience.
