After a summer break and after moving to a new apartment, I'm back with a new project. Bortle 6 skies here I come

This is the first project with the new Baader 3.5 / 4nm f/2 Ultra-Highspeed Filter set and I must say that I am very impressed with the results. The contrast increase compared to the old highspeed filters is enormous, the stars are much better suppressed and faint nebulae are clearly enhanced. So far I haven't noticed any halos around bright stars, which was a huge problem with the old filters and involved hours of work and processing.

Unfortunately I had to waste almost 10 hours of the HA channel, because without a fixed pier the CEM60 is a bit overloaded with the RASA 11". I have to find a better solution for the mount very soon, as I will not be able to pour concrete in the new apartment.

Nevertheless, over 40 hours have come together with a special focus on the OIII channel.
I hope you enjoy my version of WR 134.

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.
Dismissals 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.
