Images from modded dslr are saturated with red, is this normal?

[Rudeviewer]

Modified my dslr and now every exposure and ISO that I shoot the image is overly saturated with red.  Seems l can process it out in Pixinsight however I was just wondering if this was normal for a modded dslr.

[Chris]

Yep its normal, like you say just balance the channels in post processing

[Knight of Clear Skies]

Yes, completely normal as the camera is receiving more red light than it expects due to the removal of the filter so its normal colour balance is off. You could use a custom white balance to even it out but I find it useful as it is, it makes framing shots of nebulae easier as the Ha regions stand out more.

Ok just wanted to make sure I wasn't doing something wrong, lol.  My images are so redwashed its hard to find the object I am imaging after I take the first sub of whatever I am pointing at.

I tried a 2:00 exposure of the rosette last night, and I couldn't even make out the nebula in the image. 

[Chris]

It does take a bit of getting used to, I think I got a bit of a shock when I first modded a camera. Have you full spectrum modded your camera? if so you might benefit from a cls ccd filter. these actually swing the colour balance into the blue, but they cut out the correct region of IR and LP to reduce starbloat and light polution gradient.

I could do with one myself

[Rudeviewer]

It is not the full spectrum.  I replaced the original glass filter closest to the sensor, with a astrodon ad40d glass and left the second filter in place.

[Chris]

ooh? I don't know about that filter, I only know about the Baader replacement. I take it its a less harsh Ir cut filter like the Baader?

Looks good, thanks for the link. similar sort of thing to the Baader then

I thought I would post a single 12 minute sub that way someone else who mods their camera will know what to expect

This was taken with an Orion 2" skyglow filter

Oh dear, looks like you need to go shorter or drop the gain it's badly blown out there.

I expect the nebulosity will show nicely once the background is processed though.

I took short exposures as well to blend in that way the core isn't blown out.  This length was to get the whispy clouds surrounding the nebula.

Get an AStronomik EOS clip in LP filter, that will restore almost perfect colour balance aswell as removing light pollution, this is what they are designed for, a modded camera, I was the same as you when my camera was modded, but after getting one of those filter the colour balance is pretty much perfect. Infact now with the filter fitted I can take daytime pictures and they come out pretty acceptable, this would be impossible without the filter.

I would assume you would need a LP filter where ever you are in the UK, although I may be corrected there...

This is all stated on the Astronmik site

Hope that helps

Here's a recent test I did. A 10 minute ISO 800 exposure with my Baader modded Canon 1100D and an Astronomik UHC Clip Filter. I live in a heavily light polluted area and the UHC filter allowed the 10 minute exposure to be only slightly brighter than a 5 minute exposure without the filter.

[Rudeviewer]

Thanks for showing that single image.  Lets me know im not too far off then.

[Rudeviewer]

I use a skyglow filter that is about all that I have to use for light pollution.
