Adventures in narrowband
Veil Nebula (East)
This image of the Eastern Veil is a collaboration between myself and Allan and is our first attempt at combining narrowband filter data with an RGB image. Image details: Canon 1000D at prime focus of Celestron 80 EDR piggybacked on the BLAS LX200, guided using a Toucam pro and Metaguide. Total exposure time: 109mins RGB: 6 x 4 mins H-alpha: 10 x 5 mins OIII: 7 x 5 mins Images were calibrated, registered and stacked in IRIS, channels combined in photoshop by splitting the RGB into separate components and adding the H-alpha data to the red channel and OIII data to the blue.
