NGC 6188 Nebula

NGC 6188 Nebula (in SHO)

Description:
- This image is part of the NGC 6188 nebula which is also known as the Fighting Dragons of Ara. You cannot really see the claws in this subset.
- The full nebula is nearly 22 light years across and is a mixture of young stars and emission nebula. It is 3,800 light years away from Earth.
- This version is based on narrowband data. It is a combination of captured frames using the narrow bandwidths of Hydrogen (Alpha), Oxygen and Sulphur which have been merged to form the image. It can be considered to be artifical colour. This approach captures more structure in the nebula.

Details:
- Captured on 18-Jun-22.
- Celestron Edge 11 (280mm aperture, focal length 2800mm, f/10).
- ZWO ASI1600MM Pro monochrome camera (cooled to -10 DegC).
- EQ8Rh Pro mount, ASIair.
- 8x 300sec captures of each of S, H and O images, using Astrodon 5nm filters (2 hours).
- 10x 300sec each of Dark frames, then calibration frames of Flats, Flat Darks and Bias.
- Processed in PixInsight and Topaz Sharpen AI.
- Image size and resolution reduced for Facebook.

Location:
- APT Building, Siding Spring Observatory, Coonabarabran, NSW, Australia.

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.
