This is my first attempt of the season of the Rosette, which rises just before dawn. It is the first time I have imaged this object with the ASI 1600. Given the time constraints -- I only get about an hour and change to image this before dawn lightens the sky, this is a preliminary image. Taken over two early mornings in mid-September, the image is composed of 10, 360-second subs taken through the Ha filter and 8, 180-second subs taken through the R, G, and B filters (8x180s through each filter).

Over the course of the next four months, I hope to add at least 10 more hours of exposure to this object.

Description: November revision: This image combines 31, 300-second sub-exposures in Ha and 10, 300-second sub-exposures taken in R, G and B. Image was processed in Pixinsight, Star Tools and Photoshop. I used the Ha data for a separate HOO image of the Rosette.

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.
