NGC2174 - The Monkey Head

Revision title: Nebula and Stars separated 2nd try

Some clear nights, but with fog in the air and the moon, but I have done my best to get this image from the Monkey Head Nebula in Orion. 4 hours RGB with my Lacerta ED APO 72/432 and the ASI533MC on my iOptron GEM28

I have recognized some black structures on the stacked image, maybe that's dust on the lenses. But I don't know, why the flats haven't elimanted them... I have changed the flat creation to NINA and the Flat Wizard with my Lacerta FBC... Maybe there is still some problem. These flats are now 4sec. Previously with ASIair and Lacerta PWM dimmer created flats have 500ms imagaging time.

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.
