Using Canon dSLRs for AstroImaging...
A basic introduction to choosing and using a Canon dSLR for AstroImaging offering a couple of options for setting up your canon camera and the kit you will need.

In recent years, dSLR cameras have been used extensively in astrophotography with Canon dSLR cameras leading the way and giving some very impressive results.

The only real draw back with 'out-of-the-box' Canon cameras has been that the fitted filter can cut around 80% of the red light giving a very poor response in the crucial Hydrogen Alpha band of emission nebulae. Astronomiser offers a solution to this problem by offerring a filter replacement service for Canon and Nikon cameras.

Astronomiser's pages now include some essential advice and information on using a dSLR camera for astrophotography.

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. Buying with us means you are buying from an established business with a good track record in supplying top quality equipment for use in astroimaging which we also use ourselves - our advice will always be impartial and come from years of experience.

Canon EOS Camera Modification...

Astronomiser offers a service to modify your Canon camera to increase it's sensitivity to include the Hydrogen alpha band. This is done by replacing the original IR blocking and antialiasing filter with a Baader IR and UV blocking filter. This filter has a much sharper transition between passing visible light frequencies and blocking UV and IR giving a optimised response for Astro Imaging.

Canon Power and Pro Power DC Converters...

Converters that changes a DC 13.8v supply to suit a Canon dSLR camera. Power your camera from a power station, bench power supply or car/ leisure battery. Do away with the need for frequent battery changes and constant re-charging or the annoyance of returning to your scope only to find that your camera's battery died 20 minutes before.

New Pro Power Converters can provide a higher amperage supply with better cooling than the standard version to give a more reliable feed for cameras with higher power requirements.

These will power your camera from a power station for many hours or indefinitely when using a bench power supply. A suitable supply for use with this is available from Maplins - see the XM20 power supply unit.

astronomiser stocks adapter cables for use with this supply when using power sources without cigar socket power outlets - please see the adapter cables listed at the top of the Power and Handbox cables page.

Canon Camera Control...

Astronomiser make serial control cables can be used to operate your Canon Camera from your PC using software such as DSLR Focus.

We also offer a modification service to N3 remote controllers which allow them to be used with the 300D/ 350D and 400D models or alternatively, to allow the N3 connector to be used in conjunction with the standard serial control cables to control 10D, 20D, 30D and 40D cameras.

In all of the cables I use lightweight 2 core shielded cable to reduce the drag and weight on the back of the camera.
