I would like to present you the first test I did with my new Canon 200mm F2.8 USM L lens.
- 12 Lights @ F3.2, 400 ISO, 300s
- 10 Darks
- 20 Flats
Well, first of all, I have to say you that my location is really critical in terms of LP (I am in the centre of Belo Horizonte). I was barely able to see Al Niyat at naked eye.
Moreover, the weather this year is quite bad for astro imaging; there are lots of clouds every night.
This is the main reason why I just integrated one hour.
I used IRIS for processing, aligning and stacking.
Fits Liberator to stretch.
PS and NeatImage for refining.
