North America NGC7000/ Caldwell 20, and Pelican Nebula IC5070 and IC5067 (Roy Hagen)

North America NGC7000/ Caldwell 20, and Pelican Nebula IC5070 and IC5067

Revision title: Reprocessed with The BlurXterminator and spcc

Both in the constellation Cygnus, the Swan close to the brightest star Deneb in the constellation.
Names stems from resemblence to North America and a Pelican but in my imagination it looks like a Xenomorhp eats a fat Pelican.
Due to the dec axis guiding problems I borrowed the guide camera from the big scope, a ASI290MM and there was actually a significant improvement in the guiding stability, but the strange travels in dec axis was still present, but a lot better.
I decided to do some work on the mount to identify the the source of the problems and I found some inertia in the dec axis , but I had no problems balancing the scope in thedec axis.
I dismantled the dec axis gear from the housing and washed the worm gear with alcohol and gave it some new grease, just ordinary ball bearing grease. The bearings looked just fine so I carefully pulled off the rubber shields and gave them a drop of high performance motor oil and put them back int the housing after a while in the freezer at -20°C.
I tightened the locking nut at the end of the dec shaft very carefully to avoid inertia, put everything back in the right place, and with a lot smoother dec axis, it was absolutely impossible to balance the scope in the dec axis.
The problem is actually the weight of the ASIAIR Pro on one side of the scope which is heavier than the EAF on the other side, and the inertia made it impossible to spot the problem.
I taped a brass ring on the EAF as a counterweight to the ASIAIR Pro and achieved perfect balance in all positions.
Problem solved

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.
