Filter Reccomendations

[Colinhunter]

Please can I Have your recommendations for a good filter for red nebula. I live in a bortle 4 area which has the led street lighting using a skywatcher 130pds with an one shot colour Asi294mc uncooled camera. With a skywatcher coma corrector which reduces by 0.90 

thank you

Quite expensive but I've had altair quadband filter for few months and it does what it says on the tin.

Ok I've got a different ota but camera is osc and here's last nights result from very light polluted carlisle.

Youll notice however it takes the yellowness out of the flame.

I'm sure u can put it back in photoshop but I've not figured that out yet.

The IDAS D2 is a pretty broad band filter designed for LED lighting in mind, I have one and took the below from my B6 sky

I like it and it did make a difference...didn't work (obviously) for nights with a fullish moon so I got an L-extreme as well which is much more narrowband and took the following last week under an almost full moon 

Obviously that isn't going to be so great for broadband targets such as galaxies etc so I'll use the two depending on the targets I'm looking at.
