How do you use filters in a practical way during observation?

[Dave In Vermont]

David Knisely has several articles posted through Prairie Astronomy Club. That's where he hangs his hat. The PAC has quite a few excellent articles and such out. Very worthwhile to pay a visit. David has said it's fine to re-publish his material. He only asks to be given credit for such. He's a nice guy. I've had occasion to speak/type with him before.

I've got my filter-arsenal ready for Mars - if these clouds ever get out of my way that is.....

Have fun!

That's the one. I found it very useful.

Thanks for posting the link so that people can read the correct story and not my recollection of it.

No problem.

Interestingly, David K does not think the Astronomik O-III a great O-III because of it's rather generous band pass width but I disagree with him on that one having lived with the Astronomik for a few years !.

I capitulated around a year back and moved over to his 2 most recommended deep sky filters, the Lumicon O-III and the DGM NBP UHC-type. They are very effective of course

David is without doubt expert in visual filters, I got more info about filter use by reading his posts on CN, also an impression that he disapproves any broad band filters using the word "UHC", other than Lumicon UHC, since Lumicon had once trademarked "UHC".

The most practical way I use filters is leaving them in the house
