This is astrophoto number 4 for me so still at the bottom of a very steep learning curve. NGC253 taken Friday night with roughly 40% moon. Imaging with 130mm refractor and 1.6 extender. Nikon DSLR D700 unmodified, 18x5 min images with darks and flats stacked using ImagesPlus. I am pretty sure I got the ISO too low shooting at ISO400. The 5min exposure proved to be as long as I could go without starting to get too much noise.
Upside was this was the first time I managed to get camera control and guiding working
.
How do I smooth out the edges of the galaxy where it is rather granular. Will more signal fix this?
Other suggestions very welcome.
