IC2944 in Narrowband

[tim.anderson]

My first attempt at narrowband imaging. This is the Running Chicken Nebula (IC 2944) imaged in Hydrogen alpha, Oxygen III and Sulphur II emission wavelengths. The resulting images were combined in Photoshop and colours assigned according to the "Hubble Palette" (SII assigned to red, Ha to green and OIII to blue).

The Bok Globules (dense, opaque areas of gas embedded in the nebula) are clearly visible.

Technicals
126mm refracting telescope
ASI1600MM-C monochrome camera
EQ8 mount guided with PHD2
30 60-second frames each of Ha, OIII and SII
Stacked in Nebulosity
Post-processed in Photoshop

A good result for a first time, Tim!

What settings did you use for the camera (gain and offset)? It's hard to tell from the attached image, but you might need to take a lot more frames for each channel to reduce the noise.

However, for a first NB image, that's a good effort.

Nice result for your first foray into narrowband imaging :)
