Never noticed this one before. Very close to the pole so easy guiding as nothing moves very much round there.

Rosette Ha mosaic 6 sessions

Still a work in progress. APP is great for doing these sorts of mosaics.
5000 pixel size reduced to 2000 for this.

Object ID NGC2244/2237

Baader 7nm Ha filter
Exposure(s) Nominally 6 x 15 x 300s
but probably fewer since some will be discarded

IC349 Barnard’s Merope Nebula

By |2020-01-07T17:25:55+00:007 January 2020|Categories: Nebula, News, NGC Winter|

Thought I’d try and get the Merope Nebula as the whole Pleiades don’t fit in my FOV. But saw a flaw beneath Merope which turned out to be another nebula.

NGC 2024 Flame Nebula RGB

By |2019-12-05T16:10:37+00:005 December 2019|Categories: Nebula, News, NGC Winter|

Wasn’t expecting it to be clear so this is a bonus. Only managed 5 of each colour though so quite noisy and Alnitak overpowers eveything.

IC410 Tadpoles in Hydrogen Alpha

The two tadpoles are about 10 light years long and places of star formation.

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

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.
