Options Available
Filter Size: 1.25" H-Alpha Narrowband 7nm Filter, 2" H-Alpha Narrowband 7nm Filter
CCD imagers will find the Baader Planetarium Narrowband H-Alpha Filter 7nm to deliver the absolute highest contrast deep sky images of H-II regions, with the shortest exposures possible. Its narrow 7nm FWHM bandwidth has a transmission at H-Alpha of over 90%, while completely rejecting light pollution.
The high optical quality of the Baader 7nm H-Alpha filter 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. Coatings are professionally applied by the most sophisticated equipment available, ensuring high consistency for bandpass centering and transmission. The ultra-hard ionbeam deposition ensures the coatings will never degrade from use or normal cleaning.
This filter is available in two sizes, standard 1.25" and a 50.8mm diameter bare substrate (unmounted) for use in SBIG STL cameras.

How long will it take for my order to arrive? The Total Delivery Time for your order is calculated from the moment your order is placed until the time you receive it. The diagram below shows how your Total Delivery Time is broken down into two parts, pre-ship processing time and shipping time:
Pre-Ship Processing Time is measured from when you submit your order to when it leaves our warehouse. This time is needed for products that are shipped directly from the manufacturers to our distribution facilities. Manufacturers need this time to fulfil your order and in some cases, custom build the product.
Shipping Time is measured from when your order leaves the warehouse to when it arrives at your home or office. Your order will usually be delivered by either Australia Post eParcel or Australian Air Express courier services depending on your location. These services provide a fast and secure delivery method for your order.
*Estimated Shipping Times are based on estimated service standards promised by our couriers and are not a service level guarantee. Due to certain unforseen circumstances, shipping times could be less or more than the estimated shipping times above.
