Lion Nebula Sh2-132 HSO

Rich Ha region in the constellation Cepheus with two massive Wolf-Rayet stars with Ha and OIII radiation. Dark nebulae and dusty spaces block the last starlight. Located at 10,000 AL, with a diameter of 270 AL.

With 200 images at 7 min in HSO (23h) I reach on this image the intrinsic limits of my Takahashi FSQ telecopes as regards the resolution and the representation of the details of the relief of the nebula.Interesting to have pushed to this extreme limit where an increase in the exposure time cannot bring more details, invisible for an optic with too small a diameter.
The Takahashi FSQ 106 and 85 are characterized by a perfectly flat representation of stars on a large sensor, but lacking in detail - what are your opinions?

Thanks to Ioan Popa for his valuable advices.

ZWO 6200 – 2600 – 10deg, Tak EM-11 – EM-200, Astrodon 5nm filters, stacked in Pixinsight.

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.
