A recent purchase left me with some duplicates. Each filter includes a padded plastic box. I will sell them all for $30 including shipping in the US. Here is what I have:


Celestron #23A Light Red (25% transmission) Boosts contrast on Mars, Jupiter, and Saturn. Improves daylight observations of Mercury and Venus by increasing the contrast between the planets and the bright blue sky.

Celestron #25A Red (14% transmission) Boosts contrast on Mars, Jupiter, and Saturn. Improves daylight observations of Mercury and Venus by increasing the contrast between the planets and the bright blue sky. More pronounced effect than #23A due to lower transmission. Best for 8-inch or larger scopes.

Orion #47 Violet (3% transmission) Strongly rejects red, yellow, and green wavelengths, excellent on the Martian polar ice caps. Absolute best filter for Venus. Helps with Saturn's rings, as well.

Thanks,

Paul McCarl

P.S. I will only consider single filter offers for $12 each if no one takes the set. Thanks.
