Info about using quick change front filters with the UFC in combination with DSLR-cameras

There are no monochrome DSLR-cameras on the market, so a filter holder (e.g. the Baader-UFC) may seem quite useless for DSLR imaging, but if you take a closer look, there are indeed some interesting usage examples.

Many owners of DSLR-cameras remove the complete UV/IR-blocking filter and use this simple way to improve the sensitivity especially for H-alpha – but because of the costs, they decide not to add a new blocking filter with increased H-alpha-transmission.
But as a result, you have to find another way to block the IR- and UV-parts of the spectrum so that they will not decrease the image quality. You can use the UFC to mount such a UV/IR-cut filter in front of the camera - and to quickly replace it with another filter, without touching the camera.

Narrowband filters are not perfectly suited for a DSLR because of the Bayer-matrix, but especially a 35 nm H-alpha filter will show the emission nebulae better. For faster setups, even a narrower H-alpha filter would work well...

Especially in light-polluted areas a UHC-S or CLS / CLS-CCD filter would be very helpful. You can use the Baader-UFC to switch between several filters fast and easy. This way you can see which filter is the best for your conditions.

A Baader Fringe Killer or other filters which decrease chromatic aberration can also easily be used with great effects on an achromatic refractor telescope with the UFC. Nowadays, you can adjust for slight changes in the colours with the help of the white balance of modern cameras or software.

When a telescope – and the camera with it – faces upwards into the sky, the dust inside the telescope will fall towards the camera sensor. Pure CCD-astro-cameras have got an optical window which would stop the dust, but inside of a DSLR, the dust will come much closer to the sensor, so that it will be visible as dark spots on the image. A filter held by a UFC is an effective protection against dust falling onto the sensor of your DSLR.

As a conclusion, an UFC filter changer gives you many new options also in combination with a DSLR, and as a bonus, it offers additional protection from dust reaching the sensor of the camera.
