Hi, looking to expand my filter inventory for using on my Celestron CGX 1100 HD. Currently I only have a basic set (Celestron – 2” Eyepiece and Filter Accessory Kit – 12 Piece), but want to pick up more. Especially for deep sky observation. Any of the below categories of **used** filters would work. I'd also be interested in a color wheel - separately or with filters in place. All filters must be 2 inches. Thanks.

• Light Pollution Filters
• Narrowband Filters
• Line Emission Filters
