Celestron C11 Sct, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik filters. F6.3 focal reducer.

Large emission nebula in the constellation Monoceros.

Close up shot of the Bok globules in this nebula. These are dark dense areas of dust and gas that are star forming regions.

Data collected on two nights 5th & 6th February.

Ninety five percent moon in the constellation Leo, so worried it was going to wipe out the fine detail. Final image looks good to me.

Hubble palette image to highlight these Bok Globules Oxygen data very strong so had to do a curve adjustment to stop it overpowering the hydrogen and sulphur data.

Used my focal reducer, to get a 30 minute field of view, so I could capture some of the red sulphur data on the edge of the nebula.

Sii Ha Oii image with 8 hours and 24 minutes of data. 28 x Sii 6 min, 39 x Ha 4 min, 30 x Oii 6 minute. 2×2 binning.
