I used an OIII filter on my 80MM refractor. It was overkill. Blocked out so much I couldn't see anything (almost). I tried the Orion Ultra Block, same thing. They are made for larger scopes that gather more light. I also didn't find the color filters any help looking at the planets. Now on my 12" scope it's a different story. The OIII and the Ultra block are a big help. I've seen many object I couldn't see without the filters. I prefer the planets without filters, but if your looking for a specific detail, they can help. The red filter is best on the moon. Way better than the moon filter. Very easy on the eye like the red flash light. I don't think the filters will help on a 60MM. Good luck.
That's it;
