The Crescent Nebula HOO

Working on ASI1600mmPro Bader 6.5nm Ha and Oiii filters each stack 25x180sec Doing an exercise to compare aquisition methods between traditional Mono Camera and NB filters and an OSC camera with the Optolong LeXtreme Duo ND filter.

The OSC NB image can be viewed at https://www.astrobin.com/spcz2s/

The cameras have a 3.8 and 3.75 micron pixels so image scale is very close. Both images suffer from smoke particles in air from the Western US wildfires.

The OSC image was during a full moon and this was a new moon. Everything else I tried to keep similar.

Description: Redo from Stack. Used Ha and Oiii. Same channel mixing as OSC_NB image to try for a direct comparison between to two acquisition methods.

Description: It has been awhile since I used this camera and had to combine channels from separate images. Way out of practice!!!

Description: Final version of a exercise comparing acquisition methods between traditional NB imaging with a Mono camera and the Optolong LeXtreme Duo NB Filter for OSC's. I tried to keep overall integration time similar between to two images. The OSC NB image can be found at https://www.astrobin.com/spcz2s/B/

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.
