In recent years, dSLR cameras have been used extensively in astrophotography and the D50 and D70 cameras from Nikon have been shown to give impressive results. The only real draw back has been that the fitted filter cuts a large amount of the red light at particular frequencies, giving a very poor response in the crucial Hydrogen Alpha band of emission nebulae.

Astronomiser offer a service to replace the standard IR blocking and antialiasing filter fitted to your Nikon Camera with a Baader filter which still blocks out all of the IR and UV bands but with a much steeper cut-off which allows over 90% transmission across the whole of the visible range.

Also, if you simply wish to have the filter removed, we can do that - this will mean however that your camera's autofocus function will no longer operate. The following paragraphs apply to the filter change only.

Astronomiser has years of experience in modifying dSLR cameras with hundreds of cameras modified successfully. We also supply control cables and other products for use with your dSLR. With us, your camera is in safe hands.

Do not forget - our price includes return postage so all you pay is the price quoted below to benefit from our experience and knowledge in both astro-imaging and modifying all types of dSLR cameras.

After the filter change, if you wish to use the camera normally, you may wish to use an X-Nite CC1 type filter available from http://www.maxmax.com/aXNiteFilters.htm - other filters are available and these may be available from EU based retaillers soon.

It is possible to use a simple levels adjustment in your photo processing software, i.e., PhotoShop.

Software...

To use the Nikon D50 and D70 for Astrophotography you can either just attach it to the back of a scope and use it in manual mode or use software such as DSLR Focus, MaxDSLR (from Diffraction Limited, the makers of MaxIm DL), ImagesPlus and DSLR Control.
