Is a Orion SkyGlow Imaging Filter worthwhile

[batema]

Hi,
I live on the sunshine coast and image from my back yard mostly. Even at new moon stage the sky suffers from light pollution. Do you think that this filter (Orion SkyGlow Imaging Filter) for astrophotography would be worthwhile. To give an example tonight if I shot the horsehead through W/O Flt 110 I could probably go for 8 minutes before the image washes out badly.

A question back at you - what camera are you imaging with and do you need a filter that cuts light pollution whilst preserving colour fidelity?

If you use a camera with a bayer matrix (e.g. a DSLR versus a mono CCD) maybe consider the Hutech filters. They let more light through but seem to preserve colour balances very well. Other filters can trap more light pollution - but they can really wreck your colour balances (by shifting light or letting uneven amounts of red, green and blue through) - which makes it rather hard, if not impossible to process your image back to true colour fidelity.

I find a Hutech allows me to go for 2 to 3 times as long before things wash out.

the curve of the orion skyglow imaging filter is very close to the idas lps filter so it should be pretty much identical regarding colour balance etc.

Thanks for the replies. I am using a Canon 400d unmodified. Will read through the information but to shoot for 2 -3 times longer does sound attractive.
