Please note: Antares sources the filters in this set from different suppliers. As a result, the cardboard packaging and the plastic storage case are of two different types within the same filter set. And while most Antares filters are sourced from China, this filter set does contain some from Japan.
Fine planetary detail is almost always enhanced with the use of color filters. Since different planets exhibit different colors on their surfaces, it only makes sense that if a filter restricts a neutral color and transmits a feature color, contrast will be improved and more detail will be seen. Observers often ask which filter should be used for which planet, and for this question, while there are rules of thumb, there are no firm answers. For one thing, the colors of the details on some planets are continually changing. Also, everyone's eye response is slightly different, we're talking about very subtle detail, and the best results have to be achieved by trial and error. And since the filters can be stacked by threading them together, there are a lot of combinations to try.
We offer Antares filters in a set of 7 filters of the most popular hues for 2" barrels. Color filters are specified by their Wratten numbers. This set of 7 filters includes:
#11 (Yellow-Green)
#12 (Yellow)
#15 (Amber)
#21 (Orange)
#23A (Light Red)
#56 (Green) and
#80A (Blue)
These filters fit standard 2" threading on eyepieces and diagonals and each filter comes in a twist-type plastic case for storage.
