Modding my Canon

[Anthonyexmouth]

i've seen a lot of posts and videos on modding cameras but not maybe too many. is it possible to mod a canon to full spectrum and still use it for normal photography?

Only with an IR filter, and these days with ZWO\QHY etc. producing very good cameras, unless you really want to, I wouldn't bother....

I'd seen somewhere a baader filter replacement that seemed to make it usable in daytime as well. think it removed the anti aliasing filter too. i've got a 760d which apparently is quite well suited for astro due to being quite sensitive. its the reason i chose it, that and it was within budget. if i was going to buy a dedicated DSO camera i think i would want to see a dramatic improvement to warrant spending more money

The 'stage 1' mode removing the cyan-tinted filter massively increases the  sensitivity to Ha but you can still use white balance.

It stops auto focus working and you may not be able to focus to infinity unless you shim the sensor by 1/3 the thickness of the filter.

I've done it three times with one 'sensor kill' due to breaking the glass a replacement was fairly cheap off ebay.

The actual taking apart is easy enough, done it several times as I fitted a cold finger in my 450D

cold finger?

Copper plate attached to a peltier cooler, gets the sensor well below zero and virtually eliminates sensor thermal noise ?

[Anthonyexmouth]

how did you attach it? have you got a pic?

[Stub Mandrel]

Here are a few:

Internal appearance - note hot melt (not silicon) to seal back of sensor against condensation.

External view, note 3D printed insulation containing shield for back of finger.

Juan can do a baader mod to keep its daytime use too

[Anthonyexmouth]

ah thats the site i saw a while ago. i thought there was a mod that preserved daytime use. guess its better paying the extra to have someone do it.
