Squid Nebula HOO with RGB stars

First deep sky image for a long time. The reason was, that I had to remove my observatory and completely rebuild it at a remote location. And it took some time to build that. But now I can run automated sequences started from anywhere with an internet connection which is a big advantage as I can make mor use of clear nights ...

This is the first light with this new observatory. Don`t know why I chose this object, but I have to say: "Damn that thing is hard". The OIII line was barely visible at 180s subs with my 11" RASA and a 4nm narrowband filter (and yes I used one which is made for a fast system). After each OIII session I stacked everything and thought: "That`s not enough data!" So I collected a lot of light with the OIII filter and not so much with the Ha filter.
The stars are shot with RGB-filters and much shorter subs. Maybe I should use a lower gain or even shorter subs, because somehow the brighter stars tend to burn out a little bit. However I think, that the stars are a big improvement compared to my last images!

The objects itself is located in the Cepheus constellation next to the famous Elephants Trunk.

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.
