Description

The moon is out so time for NB imaging. The RASA 8 is an f/2 telescope and Ha was collected with the high-speed Baader Ha filter. While waiting for high-speed filters for Oiii and Sii I used the ordinary 8.5 nm Baader Oiii filter and it seems to work well.

Ha in the red channel and Oiii in the blue channel, and I made a synthetic green channel by 50:50 mixing of the Ha and Oiii data. Then I tweeked the colours towards an RGB look. All done in PS except initial calibration and stacking in PI.

Ha: 54 x 5 min. Oiii: 26 x 5 min. Gain 139, offset 50, -20°C.

Sharpless 2-132, aka the Lion Nebula, is a faint emission nebula on the Cepheus/Lacerta border, estimated to be at a distance of about 10,000 light years.
