Deep Sky with ASI120MM

Post by chripell » Thu Feb 27, 2014 8:07 am

Finally some decent weather here in Italy and I did some testing with my new setup and the ASI120MM. All the pics are with a GSO 150mm f/4 newton and are unguided on an NEQ6. All subs are 640x480 bin2

M81 exp: 30" gain: 70 subs: 31 darks: 17
NGC2403 exp: 30" gain: 70 subs: 33 darks: 17
NGC2683: exp: 30" gain: 70 subs: 46 darks: 17
M82: exp: 5" gain: 70 subs: 44 darks: 35

exactly, that night Jupiter in high resolution was dancing wildly :-(

Thanks, I must say than I'm fully satisfied with the AS120MM, now banding is really gone. I have to work on the EQ6 guiding, the stars are not pinpoint as I would like. Here is a shot without binning. I think I will do binning in post-processing only if needed.

yes, Chris.
pinpoint star is hard to get though a big newtonian

Whirlpool with ASI120MM

Post by jon » Sun May 18, 2014 2:46 pm

Here is a try at whirpool galaxy with asi120mc

Skywatcher 80ED, NEQ3-2, Autoguided
Temperature about 13 celsius, clear sky.
3 images of 300 secs
1 dark
Firecapture Gain 30, Gama 50
Debayer bilinear grbg
All processing in Pixinsight

Dear Sam, I wonder how I could achieve less overall blurriness, get some more detail on spirals as well on nebulosities that surround the two galaxies, and also some more color nuances.

Thanks,
Stevan

Thanks (Gracias) Horizontedeaton,

Ha quedado genial !
Great rework !

Was that on Pixinsight ? I don't see this process, and never used Photoshop, just 2 months into astro imaging. I started right on with Pixinsight....

Actually I was trying to know how to capture more information into the raw pictures by finding the optimal exposition lenght, number of images to be stacked, gain and gamma settings.

Saludos
