IC1848 Soul Nebula with L-eXtreme dual band

Hi folks,
Thanks to a good friend, I’ve had an opportunity to test the Optolong L-eXtreme filter with my usual rig - Sharpstar 76EDPH and modded Nikon D5500 - back in September 2021.
I went with 5min single exposure and was amazed by the signal I got. Could stack 50 lights for a total of 4h 10min of integration under a descent sky. I ran under some issues while dithering in DEC so I switched off that DEC option and had to deal with huge amount of "walking noise" during post-processing...
Finally, comparing to my first attempt two years ago with a smaller refractor and no filter, I’m very pleased by the final result!
In the mean time, I've recently found a 2'' filter on the second hand market to a fair price...and replaced the DSLR by a dedicated cooled astro-camera

Stay tuned for more image to be revealed soon

Thanks for looking at my new image and stay well!

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.
