Hi all,
Apologies for the long and confusing title, I'm a bit confused with my narrowband data and need a little help.
I have collected data of the Bubble Nebula in two different nights. From the second night I have 15 x 300s Ha, 15 x 300s Oiii and 15 x 300s Sii subs taken with Atik One 6.0 cooled down to -20C.
The first night was a bit more cloudy and I was testing my setup and guiding for the first time properly, but I managed to gather about 10 x 240s Ha and 8 x 240s Oiii, camera cooled down to -10C.
So, is it worth combining the data? Do I gain anything from it since the subs are shorter and the camera sensor is warmer? More data is more data, but are the subs that much more noisy, or does it make any significant difference really? And if so, how should I combine the data? I'm using DSS for stacking and Photoshop for processing Thanks in advance.
Cheers,
J
