ZWO Color Filter Wheel
This economical manual filter wheel from ZWO is a good match for their ASI astronomy cameras. The wheel has five positions, and as you can see from the photographs, the current position is marked clearly on the wheel itself. Simply rotate the wheel into the position you prefer.You'll need a set of 1.25" filters for this filter wheel. The package comes with adapters for both the camera and the telescope side.

- Works great. Well made.
First off the top of the 1.25 compression ring barrel is threaded for a t-ring which is a great feature not needing a special adapter if I want to hook my camera to it. I purchased this for visual use and it works great. I had to flock the inside since the path is quite shiny and reflective but after two observing sessions I'm very pleased with its performance. It's well made and doesn't have any manufacturing flaws which was a concern of mine wheni purchased it. The compression ring barrel is a nice touch on one of the cheapest filter wheels on the market. The open nature of the selector wheel makes me concerned for long term dust but since its stored in a case I'm not too concerned. I recommend this if you're looking for a filter wheel.

Product QuestionsQuestion by: bill on Feb 25, 2014 1:28:53 PMThere are a couple of ways to approach this answer...
Firstly, relative to the mechanics of the filter-wheel:
- The space between the carousel and inside-wall of the housing will allow for filter-cell heights (not including threads) of 7 MM comfortable
- The filter-wheel's carousel accommodates 2.5 MM in thread-depth
From the filter side of the equation, and not surprisingly, Lumicon's current 1.25" filter-cells conform to the measurements above just fine. The threads also mesh as expected. That being said, if you already have a selection of filters that you will be wanting to use with your new filter-wheel, I would encourage you to measure their cells to be sure.Answer by: Eric_B (Admin) on Feb 25, 2014 3:02:41 PMFor completeness sake, Lumicon filters will not fit this wheel: while the housing allows 7mm of filter cell height comfortably, the nose-piece threads project into the housing by several mm. Tried 2 Lumicon and 2 Celestron filters, only the smallest Celestron fit. Also, the tolerances/mesh of the threads is a bit tight, had to work to get all the filters in, though they did screw in, it was much more difficult than simply threading them into the nose-piece for example.Answer by: bill on Mar 9, 2014 1:23:36 PM
