About this product
The new Baader Solar Continuum filter is designed to enhance the visibility of solar granulation and sunspot details. By transmitting a specific spectral region around 540nm, free of emission and absorption lines, the Solar Continuum filter is able to boost contrast and reduce the effects of atmospheric turbulence. With the Solar Continuum filter in place, images snap to focus, and granulation becomes regularly visible. Details at the limit of visibility become easier to hold, and image motion reduced.
The Solar Continuum filter works well in all types of telescopes, for both visual and imaging. Users of SCTs and achromatic refractors will find it particularly beneficial, as it completely excludes the red and blue wavelengths, and centers on the peak visual wavelengths where the telescope optics are sharpest and free from chromatic aberrations. For digital imaging, we also recommend the Continuum filter be combined with the UV-IR Cut filter (to completely cut the defocused far infrared wavelengths).
Important The Solar Continuum Filter MUST only be used in conjunction with the recommended SOLAR FILTER for your telescope. Failure to do so will result in serious eye damage or blindness.

So I will admit straight up I am pretty much a solar-only observer and have been observing the Sun for more than 25 years in one way or another. So you might think this was an obvious purchase for me. In reality I pondered over this one for a long time as all the reviews and feedback I had read / heard were that the improvements bought about by this filter were subtle at best. Eventually I bit the bullet and went for it and I am very glad that I did. For the casual observer the benefits of this filter may be more difficult to spot but for me the improvement bought about over the #58 green filter I was using previously are marked and at times quite stark. It does take a few sessions to get used to the very green colour of the filter but eventually this just becomes normal. The view through my Lunt 1.25" Wedge / ES 11mm eyepiece and this filter is full of detail. Even now when the sun is so quiet there is evidence of granulation across the whole diameter of the disk. I haven' had much opportunity to image with it yet but what I have done has demonstrated to me that this was a good value purchase.
In summary, if you are a discerning solar observer then this filter should be on your shopping list. If you are an occasional / casual solar observer you might want to stick with a #58 / #56 or similar unless you are desperate to spend the cash!

It gives nice juicy green views of the Sun (with the solar filter on the scope). However it's good not only on the Sun. It's also good for Moon viewing (if you don't like red filters, or ND/polarising). It will also improve contrast at dusk or dawn or on brighter planets like Jupiter quite nicely.
