Astrophoto: NGC 2237 Rosette Nebula, Clear Skies 8+9

Two important evenings for me. I had a lot of time for exposures and collected a lot of data, but the result shows where to focus on in the next months.

Clear Sky Evenings

Astrophoto NGC 2237 Rosette Nebula Clear Skies 8+9.
I had two really nice evenings working on the Rosette Nebula. No real problems and in the end i was quite happe with the final result.

On this astrophoto the used EOS camera was not yet astromodified. I really like the version of this nebula much more with the OWB filter installed than the pictures without. Here is the high resolution version on Flickr:

Lessons Learned

I collected a lot of light and stacked and processed it afterwards. I was quite happy with the results and the response on social networks were awesome. Now, with a look back there are a lot of problems to work on in the next months.

  • A lot of noise!
  • So i need even more photons.
  • longer exposures
  • dithering – something i started reading at.

I still was struggling with the bad support of my CANON M100 in the astrophoto tools.
