How to make a "warp nebula" using one Riccardi-Honders f/3 astrograph and +0.6m star (USS Discovery edition=)

1h of integral Ha and OIII exposure of surroundings of Beta Cen intentionally shifted from the center of the frame to direct some of the scattered light from this star to the side of the frame, in order to increase contrast on the "Ghost of Hadar" nebula located next to the Beta Cen - captured remotely using Telescope #5 (OfficinaStellare Riccardi-Honders RH200 D = 200mm f/3, FLI Microline 16200) system of ChileScope observatory on Apr 16, 2023. The color mapping on the non-B/W revisions is Ha, OIII, Ha, Ha to LRGB.

This exercise (combined with dithering between the individual frames and integration procedure using Winsorised sigma clipping) resulted in creation of a "warp nebula" in the lower side of the frame. Also, the aperture effects created a double circle around Beta Cen that made it looks very much like a scene from [1]

and the whole image - like a capture of short warp jump across the frame as annotated on revisions B. This is continuation of the Trek series started under [2]

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.
