Sirrius Optics Mars Filter
$32.00 includes shipping
Paypal only please.

Here is some info on the filter:

Sirius Optics Mars Filter. Designed by Al Misiuk to be a interference type that transmits in the red, cuts out the yellow spectrum, and then transmits greens and blues. The increase in contrast and detail is very significant, turning Mars to a vivid red with sharply defined blue/green dark markings. Transmission of this filter is high enough to be used on telescopes as small as 80mm. According to Sirius Optics this filter may do well on other objects, but the concentration of effort has been on Mars.
