Buying a filter, it pays to learn which brand of filter would be best for the intended purpose: Visual, imaging, video-AP, etc. So do ask about this when you get down to doing so. The 'learning-curve' in words such as 'bandwith' will prove an invaluable asset.

In the meantime, here's another article from Prairie Astronomy Club and the author of the other - David Knisely - who is a "Filter-Nut," as is Yours' Truly!

Enjoy! And don't be afraid to ask me for further information about filters. I have over 40 of them, and know my way around, as do many others in SGL - regarding UHC & OIII-Filters.

As seen through my #25 Red Filter Glasses,
