Hello everyone.
Currently in a general lockdown I try to think about something else.
Then, I shot deep sky. For this image, I used a Canon 100D where the original filter has been removed and replaced by another one with higher cutoff and dedicated to astronomy. I’ve also added a narrowband filter, called Halpha.
This is why my result is monochrome.
But thanks to this filter, the contrast is really enhanced for all hydrogen clouds that emit light in the same wavelength that the filter.
All the process has been done with the current dev branch of Siril.
This is an addition of 48 images of 120s.
Hello. That is fun, thanks :).
However I should try to add true RGB channels (with no filters). The problem is that the Moon is here now. In consequence there are a lot of light pollution.
No I use a small mount that compensate the earth rotation
I love these Ha shots!
Just out of curiosity, which bandwidth for the filter? The really thin like 6nm or a broader 12nm? Contemplating getting one myself for nights when the moon is out. Just wondering if focusing isn’t just too difficult with the 6nm.
Anyway, thanks for sharing!

Evening everyone.
So I tried to add rgb layers tonight. Sadly, my mount battery was low, I did not know that. So I only shot 42 images of 60sec. That is not a lot.
