Filters

Recommended Posts

Different filters are used for different task. There are no such thing as all round filter. Obviously, the moon filter is for the moon, light pollution filter is for reducing sky glow, and IR filter is for removing IR when you do CCD imaging. In other words asking which is the best all round filter is like comparing apple and oranges.

What filters do you have?

Here are some SGL primer for filters

You'll probably end up like the rest of us and leave them in the box...once in a blue moon (excuse the pun) you'll ask the same question, get them out dust them off....and put them back again.

maybe, just maybe the Moon ND filter will get used...if you remember.

Yeah, the moon is just about the only thing that the beginner really needs to use a filter on, and only then to protect night vision. (Apart from the Sun which requires specialist devices).

When you have built up a couple of years observing experience, you will learn how to predict which filters will make certain features a bit easier to see. They do not make a huge amount of difference & are certainly not a "magic bullet" which will transform a rubbish scope into a great one, avoid the need for proper cooling or collimation or do much to work around the common issue of atmospheric turbulence ("bad seeing").

Orange or pale red usually helps a bit on Mars. It's worth trying a light green on Jupiter, and a light yellow on Saturn (but only if you have lots of aperture). When conditions are abnormally good, a violet filter may show cloud shadings on Venus.
