Vin,

<b>Just a further thought:</b> If you get a Moon filter you can use it on Jupiter. As Laurie said "too much of a good thing" is right. I find that my 12" can, at times, collect too much light and Jupiter is one of those times. Jupiters bands stand out beautifully with a Moon filter as it cuts the glare. A Neutral Density filter also works but is practically a Moon filter anyway.

12" on Saturn is perfect and does not need filtering. I tried the Moon filter on Saturn and it lost too much light! It was a dark sphere with very, very faint rings. But for the Moon and Jupiter I recommend a Moon filter (or an ND) for a 12" dob.

Just another addition or alternative to making a mask.

p.s. Don't forget to unscrew the filter when you are finished using it. I often forget and wonder why some objects are too dark and hard to see. lol
