About this product

Model:  baader_filter_36_ha_7nm-2459431
Part Number:  2459431

Baader's new Narrowband CCD Emission Line & H-Alpha 36mm unmounted Filters with 2mm glass deliver the absolute highest contrast deep sky images in H-Alpha, Oxygen III, and Sulfur-II, with the shortest exposures possible.  Their ultra-narrow bandwidths have extremely high transmissions, while completely rejecting light pollution as well as the important blocking of longer wavelengths. 

The high optical quality of Baader narrowband filters guarantees no loss in sharpness or contrast.  Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface.  This special custom polishing operation sets Baader filters apart from the standard commercially precision polished filter substrates used by most other filter manufacturers. 

In addition to their special transmission properties, the Baader coatings were developed with another key goal in mind - to reduce the annoying reflections present in other astro-filters.  To achieve this, along with excellent out of band blocking, required careful design and testing of the coating stacks. 

Coatings are professionally applied in Germany by the most sophisticated equipment available today, ensuring high consistency for bandpass centering, transmission, and out of band blocking.  The anti-reflection coatings are designed to prevent halos and balanced to prevent deformation of the substrates. The ultra-hard ionbeam deposition ensures the coatings will never degrade from use or normal cleaning.

to be perfectly honest I was a little nervous about ordering expensive Baader filters from a shop 3500 miles away from home. I did a lot of research on First Light Optics and found reviews were very positive. Secondly, the price of the filters were almost $300 Canadian dollars less than I could get them in Canada. I went ahead and placed the order with First Light Optics. Within a few days the order was shipped via DHL. Three days later I had the filters in hand. They were extremely well packaged and the filters were unopened and in perfect condition. I am truly impressed with the communications, service, shipping speed and price paid for the filters. While this was the first time I have ordered from First Light Optics, I can say with certainty this will not be the last. I look forward to ordering many more products from your awesome shop! Thank you so much! Greg McKenna, Toronto Canada
