Cave Nebula Sh2-155 SHO - first time out with 3nm Oiii filter

A couple of firsts for this one.
It was the first full session with a new 3nm Oiii filter and combining with data from the older Ha and Sii filters. Using a 3nm filter with a CCD isn't a recipe for an easy life but I'm game for a challenge.... my mount can manage 900s subs fine if the weather cooperates
Also the first time giving BlurXTerminator a try - I'm impressed to say the least.
This image hasn't had much processing but for some reason I quite like the colour balance even if there is some possible 'splotchiness' in places.
It's rather better than my 2018 Cave Nebula so I can live with it ;-)

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.
