thanks for your feedback i appreciate. After doing my 372 pics, i went to sleep, letting the camera working for the darks, that s why i have lots of them. sometime i read it s necessary to have same amount of dark than light. And i wonder something about offset. Offset are included in the darks anyway then why doing them

first try on orion nebula with my new astrodon body, 700d
not a lot of differences with standard camera on orion
i used to shoot astro with my regular 1dx.I just notice the gap in dynamic. Never had any problem on orion with the 1dx. With the crop sensor, the center of nebula is quickly overexposed.

Nice work, good color and detail.

Regarding DR, depending on the image scale yes, it's possible the smaller pixels will saturate faster than a 1D X would.

My latest image, second of 2016, the Witch Head Nebula. This is an integration of 84x300s (7 hours) subs from a dark site (~21mag/sq", yellow zone...my dark site has lost over a stop of it's original darkness, about .6-.7 mag/sq", in the last 13 months :thumbsdown: ). Image acquisition with Canon 5D III (unmodded), Canon EF 600mm f/4 L II @ f/4.5, ISO 800 (~1/4 histogram subs, with the exception of a handful of early evening subs, which were around 1/3rd histogram).

Processed entirely in PixInsight, using a synthetic luminance process where the L channel is extracted from the RGB and processed separately with deconvolution and additional detail-enhancing steps, and the RGB is processed with more heavy noise reduction.

insane work jrista, i love that witch head nebula. I already tried to target it but i see nothing on my picture lol. Maybe one day if i m lucky enough to have a perfect clear sky , almost impossible in my cloudy country

Here is a new version of my flaming star nebula, with better colors i think
same picture same previous one, just different editing and framing
