Deep Sky Images taken with a Sky Watcher 80 Esprit triplet refractor fitted with a field flattener using an ASI 533MM Pro camera and EFW:
Crab nebula (M1): Just an hour of SHO data taken on the morning of the 17th November of this most famous of supernovae.
Sculptor Galaxy (NGC 253): This is also known as the Silver Coin galaxy and its easy to see why! 90 minutes of RGB & Ha data taken on the evening of the 17th November as this southern hemisphere galaxy made its brief appearance in our skies at this time of year.
Witch Head nebula (IC 2118): A two pane LRGB mosaic taken over the nights of the 16th, 20th and 24th November of this reflection nebula which is illuminated by the star Rigel in Orion. Approximately 2 hours integration on each panel.
Flying Bat and Squid nebula (SH2 -129): Some additional SHO data was able to be taken over the nights of the 17th and 20th November to combine with 2.25 hrs data taken in September giving a total of 7.5 hrs integration on this most interesting nebula.
Comet R2 Swan: An hour's RGB integration of this recently discovered comet taken as it passed through the circlet of Pisces on its way back into the outer reaches of our solar system.
Rosette nebula (Caldwell 49 & open star cluster NGC 2244): Three hours of SHO data were taken on the nights of the 20th & 24th November which I integrated with an additional 2.5 hours of RGB stars data taken last January. I also processed the RGB data separately. This nebula and adjacent star cluster located in Monoceros lie just 5,000 LY from Earth and being ~ 130 LY in diameter comprise a large and bright target for amateur astronomers. On the 20th I was only able to acquire 25 minutes of HO data which I integrated to show how easy it is to get good results form just a small amount of data.

The Wizard nebula (NGC 7380): On the evening of the 25th November I took some 5 hours of SHO data on this most beautiful nebula that lies in Cepheus at a distance of 8,500 LY from Earth. The centre of the nebula is best seen with the stars removed in the cropped starless version.
The Sun in Ha light: At noon on the 24th November I used a PST piggy back on my SW 80 scope to image the Sun in Ha light using a Player One Apollo-M-Mini camera. Some 21% of a 1,000 frame SER were stacked in Autostakkeet4!, wavelet processed in Registax and further processed in Pixinsight's solar toolbox.
