At the end of 2005 I bought a Canon 350D Digital SLR, partly for astro imaging and also for 'normal' use. Once the warranty had expired, I had it modified to remove the existing infrared filter and replace it with one which passed the important Hydrogen-alpha light. Although this can be a DIY project, I played safe and had the experts do it! In this case a local company Astronomiser who did an excellent job at a reasonable price. |

With a suitable adapter the camera can be fixed to a telescope in the usual manner: |

Early Summer 2014 I replaced the 350D with a 700D. Although not modified, I wanted it for other photography, and the 'live view' tilting screen makes focusing a joy. But in early 2015, I bought the 350D back from the guy I sold it to! I missed the Hydrogen-alpha capabilities, it had come up for sale (at a lower price!) and I didn't want to modify the 700D because there was a chance that the autofocus system would lose accuracy.
In Autumn 2018 I finally took the plunge and had my 700D modified by Andy Ellis of Astronomiser - it was now clear that the filter modification would not affect the autofocus. And I again sold the 350D at the September 2018 Kelling Heath Star Party. So from 2019 on all DSLR images will be taken using the 700D.
