Primer on Filters in general

[AstroTiger]

Hi all

I have just read with great interested, indeed i have copied the thread for reference which GazOC wrote on planetary filters.

Is there anyone here who might be able to do an overall primer on these things.

Use of L filters for example, UHC, OIII.

These things seem to be coming down in price now, and i think it would be of great help if someone might be able to expand on all the different types of filter there are and what they are for?

Many thanks in advance

No volunteers then lol

Nevermind, the way i am going i think i might be able to write something here soon :-)

Thanks anyway

Al, I've only just noticed this. I haven't got the knowledge to do this myself, but I think it would be really helpful if someone could, if they have the time. Think you might go ahead with it? It'd be useful to know what kind of colour filters are for observing what objects, UHC OIII (I had to google these when I first started on SGL!). Perhaps not just for visual astronomy, but also for astrophotography too... be a great thread to point beginners towards.

Gaz's primer is excellent for planetary observing, btw

Thanks Amanda,

However given the lack of response, i think it will be written but i doubt i will publish it here.

Little point if no one see's it :-)

Thanks again

I found this Article on filter comparisons as I was searching SGL just now, as I was sent an Baader 0111 filter as an early birthday gift from a relative.

Thanks for the link, looks like a lot of work has gone into producing that article.

I could knock somethign up...

I have my own opinions on filters but I'll do my best to be as objective as possible:D

In the meantime that link just posted is an excellent resource and should be used as a guide to what filters work best for what targets

Just a note to say that I would love to read such an article AstroTiger.

Thanks guys

That primer will be done at some point.

At the moment i am mastering LRGB image processing with some success using the tutorial which was posted (where i forget off hand, but it was very good)

Just an FYI, i am recording another, but with a few extra bits which i feel its predecessor did not cover.

Will let you know when its available (next week sometime poss)

Cheers

I have written a primer on using visual filters. If you have anything to say about it, please let me know in this thread!

Synchronicity - I just did a review on O-III and UHC filters.
