Narrowband filter recommendations
Hi everyone,
I'm researching filters for my newly acquired atik 314l+ mono. Having established that 1.25" filters should suit, I am now looking into which narrowband filters I should look for.
The reason I'm a bit confused is with the varying bandwidth of say 12nm down to 3nm for the Ha filters. Is the 12nm Ha filter less suitable for imaging during times when the moon is out and in areas of moderate light pollution or do I have to go for something with a narrower bandpass?
Also, if I could ask whether the 3nm astrodons are available locally because I only seem to be able to find the 12nm astronimik and the 7nm Baader.
Thanks.
