Rosete with Canon EOS 350 D from Europe

[astropintr]

Dear south guys,
I took picture of Roseta nebulae last week. This is my first picture of this year (because cloudy on winter sky). Picture has defects, but I am happy, that this is my first picture for this year. There is signal noise and small artefacts on stars, but result is for me acceptable.

Wow, nice work. Loads of detail in the structure of the nebula, the ED80 plus modded 350D perform like champs on this DSO. Interesting that you used ISO1600, the 350D usually doesn't do so well with noise control at that level. However, if the temp is sub zero (like you had during the image run) it can help.. a lot

Hallo,
thank you for your reply. Basicly I am using ISO: 800. But if temperature is going down under zero, I am using also ISO:1600. But you need more light frames for elimination of noise.
