IC342 (Hidden Galaxy) in Ha NIR LRGB

IC 342 is a galaxy that lies behind the milky way dust. This obscures the signal from the galaxy. The shorter the wavelength the more the light form IC342 gets scattered. This makes the galaxy appear reddish.

To boost signal in the image, I made a synthetic luminance layer from the luminance filter (7 hours) and from the data i shot with an Astronomik IR642 Pro planet filter (2,5 hours). This filter is a NIR pass filter, and passe 642 to 840 nm. The data from the NIR filter was much cleaner then the Luminance filter, while being illuminated only 1/3 of the time.

This shows that LRGB objects in the milky way plane can really benefit form IR Pass filters.

Title: NIR-NIR-L representation

Description: This was the RGB image from the NIR 642-840nm, NIR >804 and luminance filter I made. Just to show that NIR penetrates the galactic dust better as the image comes out green

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.
