Adding to my collection of galaxies so far this month , I captured M83 Southern Pinwheel 2 weeks ago on the South Coast NSW at my dark site costal property ( retirement getaway ) on a moonless clear night ( Bortle 3 skies )
NexDome Obs
8” f5 GSO newt
Skywatcher EQ6-R mount
Imaging camera ZWOASI2600MC set to Ascom Highest Dynamic Range cooled to -15C
Guide Scope Orion 60mm with helical focuser , Guide camera ZWOASI120MM-S
45 x 3 minute dithered guided subs
PHD2 Multistar guiding at 0.70 arc sec total
Goto and Nav EQMOD and Ascom Stellarium
Framed focused and captured with APT
Stacked in DSS
Processed in Startools V1.7 OSC Linear data set

Image is probably a bit to heavy with colour saturation ( blue in particular) but I thought it exposed the spirals a tad better

I discarded about 4 subs due to satellites , probably Elon’s Starlink trains

Comments most welcome
Thanks

Looks like the dark skies gives you plenty of detail opportunities, nicely done in the core.

I like it M

I wonder how the OSC could capture the red, it has been done.

Clouds are back...

Well done :thumbsup:

Thanks All,
M83 is a great target to image this time of year and is within the reach of most scopes being quite bright at magnitude 7.5

Being a face on barred spiral galaxy a significant amount of detail can be exposed in your images

I may image it again before Winter is over
Thanks again for your comments
