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.
