IR/UV Filters - which do you use?

[kev]

Im just wondering to myself...

Ive been using a Toucam 740 with a TTL IR/UV block filter. Works nicely, and Ive now got a SPC900.

What filters do folk out there use with their webcam? There are so many out there, has anyone ever treid a side by side comparison?

a) witha barlowed configuration (on a newtonian or similar) - which would therefore introdice some (very small) anmount of chromic ... which may affect IR focus.

With a standard achro refractor?

What do folk you and how do you find it?

PS With my Vixen ref I find adding a "Contrast boaster" to the IR/UK helps no end, but makes no difference to the barlowed config.

I tend to use the Baader Planetarium one.. but also use the Baader Neodymium as welll.

I have the version with the "cut" - the earlier ones didnt...
