350D Mod Gone Wrong - HELP!

[Stephen]

Not my mod, but need some help for a friend as this one has me scratching my head.

The 350 was sound before mod (filter removal, no replacement.)

Post mod the camera takes good (red tint obviously) daytime photos but ...

Astro shots are covered (and I mean all over the image) in what "look" like stuck pixels.

Any pointers or suggestions welcome

How long an exposure was that shot Stephen?

What telescope is it being used with? Open like a 'flector or closed like a 'fractor?

[Digz]

Looks like a very noisey image to me unless I'm looking at the wrong bits? What ISO was used? Is this a stretched image?

[gkec]

I would say noise as well. Possibly a bad connection near the sensor.

What I can answer off the top of my head

127mm Acro

ISO 800

30s sub or less (can't confirm that)

Noise (what it appears to be) is incredibly worse than pre mod

Connection was my first though, he's stripped and rebuilt it this afternoon

Pull it apart again and refit and ensure all foil plug and socket connectors to ensure all are connecting properly.

It took me three strip downs to resuscitate my 1000d after I modded it, those plugs and sockets are fiddly and look like they are connected but more often than not they aint.

Problem resolved, thanks for the advice.

My mate has changed the chip to one from another camera - I'm not sure that's fixed it, but I suspect the ribbon cable from the sensor assembly was loose. Either way he's up and running again
