With essentially two filter mounting options. Drawer or Wheel. The Zwo drawer is a nice choice for OTAs where a low wind profile is desired. <br

This finder shoe is well worth the money. It is very solidly made and should last a lifetime. The shoe has excellent material and looks as great as it works. I highly recommend this for your use,

Purchased this for covering my 12" SCT and new Losmandy G11T mount. Fits perfectly, and is a good value for the price (this is not a 365 all-weather cover, as HP clearly points out, but very effective for what it's intended for.) Appropriate materials and construction. Recommended.

Terrific.

Fits my 10inch DOB just fine

I bought this Groupon filter from Telescopes.us.com and it is working as expected.

I went to take out pictures using this filter on a couple of nights and the filter and reduces the light pollution due to city lights very much. There is a lot of vignetting occurred due to this filter, though nothing that cannot be fixed in post proce

ssing. I recommend this product for medium to high light polluted areas.
