Double-stack your Coronado PST with this 40mm double stacking filter and see more! No need to send it into Coronado for matching...just screw the doublestack filter onto the end of your Personal Solar Telescope. Adding a second filter lowers the bandpass to <0.5A, which will yield views showing dramatic increases in surface detail.
Are you looking to see significantly more surface detail, but are not yet ready to take the plunge into the larger Coronado Solarmax solar telescopes? By adding the PSM40 double stacking filter to your PST, you will dramatically increase the amount of surface detail visible on the sun. There are certainly limitations on the Coronado PST due to its size and optical resolving power, yet you will be impressed by how much surface detail you can resolve with the 40mm solar filter added.
Cannot be used without a secondary interference filter. For PST Telescope only
