        Comments about Baader Planetarium Semi-APO Telescope Filter:

        This is a nice filter and works great for removing the purple halo around bright objects. But it dims the image to much in my 4" refractor. I would say this would be a great filter for 5" and larger achromatic refractors. Another nice feature is the image is not yellow like some filters. If you have a 4" or smaller refractor go for the Fringe Killer instead.

        Comments about Baader Planetarium Semi-APO Telescope Filter:

        This filter eliminates most of the purple fringing in my meade ar-6. You can still see a small amount of purple around jupiter, but it is greatly reduced. It does a excellent job of letting light through with just slightly darker views when it is on. You can leave it on for all your viewing for the most part. I did remove it to view some of the faintest objects and did notice slightly brighter views without the filter.

        An excellent product. If you have a good achromatic refractor, this filter will make it.. 'semi-apo' !

        Why spend $thousands for an apo when you can enjoy your good achromat.. er, semi-apochromat !?? It is THAT GOOD !

        Comments about Baader Planetarium Semi-APO Telescope Filter:

        Dramatic reduction in chromatic aberration in my achro refractor. Yielded crisp well defined images, and increased contrast of the Moon and Jupiter with little or no discernible color tint. Only a very thin color (purple) halo on Lunar limbs.

        Service and delivery comments:

        The service was excellent; the delivery was prompt - just a couple of days as promised.
