M83 Southern Pinwheel Galaxy

[Startrek (Martin)]

Finally captured some reasonable data on M83 over the past couple of nights although outside ambient temperature was quite warm for this time of the year ( about 19 degrees) Doesn’t help the DSLR though trying to push longer subs to capture more detail , you get swamped with noise in the process

8” f5 Bintel newt on an EQ6-R Mount
Canon 600D stock with a Baader coma corrector and home made cooling fan ( reduced cameras sensor electronics by 5 degC )

ISO 800
50 x 5 minute dithered guided subs
25 x darks
PHD2 guiding at 0.80 to 0.90 arc sec error
Medium dithered each sub
Stacked in DSS
Processed in Startools V1.5

That's a ripper, time to move on; onwards and upwards as the old saying goes.

That’s a cracker of an M83 Martin. Well done.

It's certainly paid off. Lots of detail, great colour and perfectly round stars.
Excellent Pinwheel all-round!
