Rosette Nebula (Cyrill Durrer)

Rosette Nebula

After tweaking and modifying my equipment, I decided the capture again the Rosette Nebula. So I was able to compare afterwards with my previous version I already did. I changed the following:
- Telescope the same TS-APO 140/910, but now with William Optics Flat6AIII Redcuer, gives me 728mm and F/5.2
- Optimized Backfocus (Took me lot of time because the reducer is by manufacturer not designed for kind of this scope, but sharpness is incredible)
- Optimized Backlash of my ZWO EAF focuser
- Optimized guiding, now with a WO Zenithstar 81, gives me constant guiding below 0.6 over 600s with my CEM70G
- Changed the camera and using ASI294MM with Bin1 for most details possible
- Took additional time to capture RGB for the stars

I'm really happy with the result, I think more is not possible with my equipment. Any next step into details etc.. needs new mount and scope

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
