North America Nebula (H-alpha RGB)

For this image of the North America Nebula, I combined H alpha I acquired with a cooled monocrhome camera with some older RGB data from my DSLR. I wasn't quite sure what to expect, but the result turned out better than anticipated. My original intent was to obtain OIII and SII data as well, but unfortunately the weather here has not been cooperating. In addition, re-assembling all of the color data in this way always gives the image an artificial look. This combination seems a bit truer to the actual appearance of this nebula.

In each case, the camera was paired with the Samyang 135 mm lens set at f/2.8. For the DSLR data, I had the camera / lens mounted to my C8 telescope and used a 50 mm guider. This data was taken from a dark site (rural skies, with the Milky Way visible to the horizon.) As for the more recently acquired H-alpha data, this was acquired from my back yard in the Bay Area. I used my 80 mm refractor for guiding. The image was processed in PixInsight. I used the Automatic Backgroud Extraction, Color Calibration, and Background Neutralization to get the color reasonably accurate.

Wishing everyone clear skies for the summer!

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.
