Full Spectrum

[Paulggg]

Im expecting my Nikon D5300 back this week with full spectrum mod for astrophotography.

Can anyone advise me on what filters are best for DSO photography.

Still learning

This is M42 a few weeks ago with unmodified DSLR.

I'm not up on filters for a modded camera. Others here can advise on such.

With this image, I guess it was tracked? I think that maybe double the exposure time
would give you a "cleaner" (more colour saturated and less noisy) image, but it's not
too bad. I would not have gone much higher with the ISO setting (maybe 800 max)
for the same reason.

With visible-light-only images, a bit of post-processing can help, and I have tried a bit
with this one using Photoshop. But a better exposure would be best.

Lastly, what optics did you use? The Exif reports a FL of zero and an f-stop of the same.

Excuse the ignorance but whats a full spectrum mod?

^Basically, you remove the any non-colour-producing filters, such as UV and IR blocking
filters that the camera may have. That way you get all wavelengths that the sensor is able
to record. You can also modify a camera to record more "Hydrogen-alpha" light.

Here is a comprehensive video that talks about both, but you may find shorter ones:

Search on hydrogen-alpha mod camera or on full spectrum mod camera.

Thanks. Another YouTube wormhole coming up...
