Poor night of transparency and seeing so just got this in the passing. Lots of sky fog that got processed out.

NGC 2264 Christmas Tree Cluster narrowband

After a HOYS-CAPS session added narrowband. Rat’s head in there?
No more MPCC and stars are much sharper at the edges.

M42 for 2019 narrowband

By |2019-01-29T21:36:10+00:0029 January 2019|Categories: M31-60, Nebula, News|

This year in narrowband. Two attempts at colour mapping.
Need to get rid of the MPCC with this telescope as the image is better without. Too much star trailing with.

B33 Horsehead in narrowband

By |2019-01-14T16:26:53+00:0014 January 2019|Categories: Dark nebula, Narrowband, Nebula, News, NGC Winter|

First real narrowband image. Strange reflections of the primary, secondary and spider in Ha and OIII images, as well as flats.
Mappings were OHS and HOS. SII didn’t add much to either image but object is strong in Ha and OIII.
