Messier 81 & 82 with Optolong L-eXtreme (First test)

I just received my Optolong L-eXtreme filter and wanted to test it with Celestron 9.25 ED equipped with a Hyperstar (f/2.2). I read that this filter does not allow imaging of galaxies. Well... I tried anyway just to see what would happen ... and even though I took only a few 180" subs, I was positively surprised by the result. The integrated image was only lightly post-processed: a bit of saturation adjustment in APP and black point increase in GIMP.

Nikon/Tamron data:
ISO: 1600
Subs: 38x180s and 20x300s
No filter
Date: January 11, 2021

Description: I used some older data [Jan 11, 2021] that I collected with my Nikon 7100 and Tamron 150-600 (@520mm) [ISO 1600, 38x180s, 20x300s] and integrated this with the data obtained with my Celestron 9.25/HyperStar/L-eXtreme. The orientation of the camera was different (about 90°), and the scale was a bit off, but APP handled this really well.

Title: Integration of L-eXtreme and L-Pro subs

Description: a few weeks ago, I took 80x120s subs with my L-Pro filter and combined those with L-eXtreme subs and processed the image in PI. The surrounding dust starts to appear.

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.
