Astro physics 0.67 reducer.

Bright emission nebula in the constellation Auriga.

Hubble palette image to bring out the detail. Weak oxygen component and it is mostly hydrogen and sulphur.

Near the bright star Capella that I used to check the focus with a barthinov mask. Good focus is critical for decent deep sky image.

I did try an LRGB image but I getting reflections off the focal reducer with the bright star. No such problems in narrowband.

Data collected on 3 nights. 8th, 21st November & 8th December.

Sii/ha/oiii image with 5 hours 50 minutes of data. 8 x 15min Sii, 11 x 10min Ha, 8 x 15min Oiii 1×1 binning.
