Tri colour Imaging

 

Well after what appears to have been an eternity I have finally managed to start Tri colour imaging. The techniques uses a monochrome CCD camera, in this case an SBIG ST-10E, and a series of filters in a True Technology Fiter Wheel.

Images are taken through a clear, ( the luminance channel), and then corresponding Red, Green, and Blue chaneels. All images taken with the Takahashi FS128 at f8. Images taken using CCD soft, aligned combined wityh MaximDL, and tweaked in Photoshop.

 

These images below are my first attempts at imaging this way, and whilst I am pleased with them, they need more exposure, and better processing. The compression for the web also seems to have degraded the image quite a lot.
I hope over the winter period to develop this technique of LRGB, and in particular using the new 12.5" RC due soon.
