      Comments about Baader Planetarium Narrowband H-Alpha Telescope Filter 7nm:

      I purchased this primarily for adding Ha to my RGB images that I take with a modified DSLR. I've only imaged NGC 6888, the Crescent Nebula, so far and am extremely pleased with the combined HaRGB image.

        This Ha filter fits perfectly into 2" threaded adapters for astrophotography. It is very high quality and comes in a great case. I can't wait to do some long exposure astrophotography with my modified canon DSLR with this beautiful filter! Great for narrowband imaging.

        An Excellent Narrowband Filter

        By Budboy

        from Derry, NH

        About Me Casual/ Recreational

        Verified Buyer

        Pros

        • Great Optics

        Cons

        • Deep filter cell

        Best Uses

        • Astrophotography

        Comments about Baader Planetarium Narrowband H-Alpha Telescope Filter 7nm:

        This is an excellent filter for narrowband imaging of emission nebulae. The 7nm bandwidth provides high contrast images and allows you to image even with a full moon. Most filter cells average around 7mm in depth. The cell holding the Baader filter is deeper so this filter may not fit in certain filter holders and filter wheels. Make sure you have adequate space in your filter holder or filter wheel to accept this filter. One solution to this problem is to remove the glass filter (very carefully)from its cell and install it in a thinner filter cell. You will loose the advantage of Baader's extra thin cell wall, which provides the most clear aperture of any 2" filter available but at least you will be able to use this excellent filter. Please note you will have absolutely no problem if you are screwing the Baader onto the barrel of a 2" eyepiece or extension tube.
