NGC40 Bowtie Nebula

Acquisition type: Lucky imaging

I capture some data on NGC40 back in July to test out my new duoband narrow band filter (OIII+H-alpha and H-beta). I decided to try and combine this with some partially processed RGB (UV/IR Cut filter) color data from back in August of 2020. After several attempts, I got an acceptable result with stars and star colors from the 2020 data and the nebula from a combination of the UV/IR cut and the duoband filter data. I'm still honing my techniques on combining image data from different filters!

Take a look at version B, which is enlarged 200% to make the fine detail in the nebula easier to see.

NGC40 is about 6500 light years away from us and the bright core is roughly 2.2 by 1.5 light years across. It is exceptionally bright in Hydrogen alpha, giving it an intense red color. Because of this, when imaging with an RGB camera, or LRGB filters, it is difficult to show detail in the nebula without a lot of tinkering with the color. I solved this by significantly desaturating the nebula in red only.

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.
