Daz Type-R Posted November 6, 2012 Share Posted November 6, 2012 Stunning! How do you know what exposure lenghths to go for, for each RGBL channel? Is it just trial and error over years of experiance? Link to comment Share on other sites More sharing options...

Guest peter shah Posted November 6, 2012 Share Posted November 6, 2012 thanks everyone. daz/sheila, the exposure is basically as long as i can, ive tweaked my polar alignment and have managed to double my exposure lengths....the difference in exposure times in each channel is my g2v exposure weights, which is basically a white balance for my camera, filter and scope combo....the scope is calibrated on a G2V type star that has a similar spectrum to the Sun, which is white light. This type of calibration makes colour balancing much easier. Link to comment Share on other sites More sharing options...
