NGC 6888

This nebula is about 5000 light years away from us. It was discovered by William Herschel in 1792. It is formed by the stellar wind of the Wolf Rayet star WR136.

I decided to come back to this iconic target with my C6. Of course this picture is far behind from those of the masters in AB but nevertheless it was fun to process it.
4h59 of exposure time, I am quite sure that 5h would have spoiled it

.

Anyway it is done at f/8, so photon flux on the sensor is not great. The Starizona reducer of 0.63 actually provides f/8 on the C6, this is the nominal value when combined with a C6 SCT.

I tried not to overprocess it. I find that often the nebula looks a bit "pasted" on the background with the OIII pushed to a critical level and Ha zones burnt out. Actually the dynamics of this target is quite difficult to handle.
Hope you can like it.

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.
