M31, M42, NGC 2024 ja IC 434 - 9.12.2016 at 22.00 Iitti Observation number 58909

Visibility III / V

Ari Ollikainen, Konut tählet, Jaala

After a long "dry" period, I was forced to get to shoot, even though the Moon made the conditions moderately challenging. So I stayed at the traditional sites to recall all the things I learned through trial and error. Well, always include a few blobs to fit. When shooting the M42, I tried a Hoyan Red Intensifier filter for Tamron 70-300 mm I bought from the Yankees. Focus was a bit wrong. In the moonlit sky, the difference to images without a filter in the past was by no means shocking. The experiment will continue as long as you can fire into the dark sky. Canon 7D MKii camera.
