I am a complete n00b with filters and figured I would ask away in the experienced section. I am looking at two different type of filters to create the following types of images with my ASI533
Based on the post James recommend the following filters
L-eXtreme Dual Band 7nm HA/OIII Filter $239.99
Astronomik SII 6 nm CCD Filter $199.95
Being forever frugal with my money (not sure it's possible with AP) I wanted to understand the difference in nanometers and how it would effect my images. I was looking at the following filters
ZWO 1.25" Duo-Band Filter which has HA at 15nm and OIII at 35nm $99.00
Astronomik SII 12 nm $129.95
Can some explain to me in layman's terms how these filters are different in terms their capability? I realize the nanometers are different and the only thing I can guess based on that, is the lower the nm number maybe the better quality the filter is in terms of isolating a specific band? Just a guess but sounds reasonable in my head
Any assistance is always appreciated!
