Canon EOS 350D dismantling for astro modifications

[Gina]

Since Gary Honis doesn't list this camera model on his website I though I'd post how I'm dismantling it for filter removal and removing the CFA Bayer layer to convert to mono. Hopefully this will be a help to anyone contemplating filter removal with this camera.

The screws are the same as for the 1100D so the screwdriver I used for that fitted nicely.

Before removing any screws I took a sheet of paper and stuck some strips of double sided adhesive tape onto it. This will hold the screws and enable putting the screws back in the right order - right length screws etc. I also removed the battery and CF card before commencing.

Firstly, I went all over the outside of the camera removing the screws. Some were under the viewfinder eye shield and some inside access flaps.

A couple of photos showing the screw tidy and view of the camera after carefully prising the back off.

Been given a link to a dismantling tutorial (thanks Luis) which is much better than mine so I'll point our readers to that and continue from where that leaves off when I get there

Can't understand why they've took the front cover off ?Another tut here that doesn't involve taking the front cover off

Hi there,

It's much easier to work with the front cover off, this will allow to lift the upper sction (where the shutter / viewfinder is) slightly and remove / reinsert some of the ribbon cables that are on the upper side of the main board.

Just be very carefull with electrocution, if you touch the flash capacitor it's one hell of a ride...been there, done that 340 V is no fun...

Cheers,

Interesting But in that tutorial they cut away a piece of the case to get to a screw. I presume taking the front off avoided that - I didn't have to cut any of the case away and now have the sensor assembly out.

Further dismantling including removing the filter complete with it's plastic box.

I then put it all back together (except for the case screws) put a lens on and took a couple of photos out of the window at different zoom factors. These were "adjusted" for brightness and contrast only in Photoshop.

Sensor back out again ready for cover glass removal - job for tomorrow

This debayering is all very exciting and I wish you lots of luck with this Gina I'm seriously considering following in Luis and your foot steps with this one again using a 350D.

I've just limbered up by modding my canon 1100D, finished the whole of 15 minutes ago, I won't try debayering this one though

[Gina]

Thank you

I'm using the 350D as a practice working sensor as tthe 350D only cost £65 whereas 1100D bodies cost about £200 second hand Hopefully I won't destroy the 350D, I shall certainly try hard not to. After the 350D I shall be attacking the 1100D
