Jellyfish in the Ocean Of Space

The Supernova Remnant IC443 otherwise known as the Jellyfish Nebula and Sharpless 248, lying at a distance of approximately 5000 light years from us in the constellation Gemini, visible towards the top left in this image is the Jellyfish, the remains of a supernova that occurred between 3000-30000 years ago, lower right in this image is the diffuse and reflection Nebula IC444 otherwise known as Sharpless 249.

Captured using data from Grand Mesa Observatory's system 1 the Takahashi FSQ 130 (available on our subscriptions) using the new QHY367 Pro C full frame One Shot Color CMOS camera with Chroma Narrowband Filters.

In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. Then I used the naturally colored stars from the broadband image, while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.

Captured over 5 nights in January and February 2020 for a total acquisition time of 16.5 hours.

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.
