The Iris Nebula / first light Zwo ASI294MC Pro camera

Post by Menno555 »

The Iris Nebula / NGC 7023 / The Netherlands, Bortle 8

This is just a test/work in progress, I have a new camera: Zwo ASI294MC Pro. But with it also a bit bigger FOV, so starting to push my unguided Ioptron CEM25EC.
I did know that 60 sec unguided was no problem but now hitting 120 sec unguided and no problems. I think that 4 minutes unguided is possible and that with an 8” f/10 SCT! The mount keeps on amazing me!

This is also my first reflective nebula capture and the processing the colors is a bit different I noticed, I have to get used to that. So made an B/W version.
This is just made with not that much data but next version will have several hours and color (probably). Still thought to share being it first light of the camera.
