NGC 7538 Bicolor

This little nebula is perhaps bigger than it looks. It lies 9,100 lightyears away and contains the argest known protostar--300 times the size of the solar system. I think that includes the Oort Cloud, so that is BIG. This is a bicolor HaOIII that started as a wim. I needed an Ha target to shoot during a bright Moon. I hope to collect the SII for this image, but I do like the red tint from this HaOIII composition. I typially do not have much success with bicolor images. Even when I do OK with one, I am never sorry I collected the SII afetr I decide to do it.

This image was complicated by the fact that I rotated my camera, using the CAA for the first time, so I could frame the Witches Broom. I forgot that I had collected the Ha for this target and realized that I would lose a lot of the FOV. It seems to have worked out OK as I planned on cropping anyway to better reveal the details of this smallish target.

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.
