Between Tulip and Crescent - 202 120 secs unguided subs taken on the 13th of August 2021

This image is the sum of 202 120 secs unguided subs taken on the night of 13th of August 2021 from my home terrace. SEtup was a Canon 70-200 F4 lens (used at 100 FL) an ASI 533, an Optolong L-Extreme filter on top of an Ioptron Smart EQ.

No darks and flat was used. Aquisition done with Astroart. Almost no processing. Only the gradient removal with Astroart and then the JPG optimization.

I think this is a very nice area of Cygnus constellation, with many interesting objects in the middle.

Thanks for looking

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.
